P2583 on 2019-2024 Volvo S60: Front Sensor Fault Causes and Fixes

What's Unique About the 2019-2024 Volvo S60

The 2019-2024 Volvo S60 is built on Volvo's Scalable Product Architecture (SPA) platform, which heavily integrates advanced safety systems. Unlike older systems with separate radar units in the grille, the S60 combines the camera and radar into the single ASDM unit in the windscreen. This design makes the system highly sensitive to windscreen condition and calibration. Even a tiny stone chip in the wrong place can trigger this fault, often requiring a full windscreen replacement and mandatory recalibration, rather than a simple sensor swap. Aftermarket windshields may not calibrate correctly, with many installers recommending only genuine Volvo glass.

Symptoms You May Notice

• "City Safety Service Required" or "Collision Avoidance System Unavailable" message on the dashboard.
• "Windscreen sensor Sensor blocked" message on the dashboard.
• Adaptive Cruise Control (ACC) is unavailable or will not engage.
• Pilot Assist feature is disabled.
• The Lane Keeping Aid system will not function.
• Traffic Sign Recognition may stop working.

Most Likely Causes

1. Obstructed Windscreen Sensor 🔴 High Probability The ASDM sensor is located inside the windscreen, making it susceptible to any external blockage.
   How to confirm: Visually inspect the area of the windscreen in front of the rearview mirror housing. Look for any dirt, mud, snow, ice, bird droppings, or even a poorly placed toll tag or sticker.
   Typical fix: Thoroughly clean the windscreen. Use the vehicle's defroster to melt any ice; do not use a scraper, which could damage the glass or the embedded heater grid. The warning message should clear on its own after cleaning and restarting the car.
   Est. part cost: $0
2. Sensor Misalignment / Requires Calibration 🟡 Medium Probability This is a very common issue after a windscreen replacement, even a minor front-end impact, or hitting a large pothole. The system's accuracy depends on precise alignment.
   How to confirm: This is diagnosed if the code appears after a windscreen replacement or impact, and cleaning the glass does not resolve it. A professional scan tool is needed to confirm a misalignment status code. Some glass shops will refuse to work on the vehicle if it's already showing calibration errors.
   Typical fix: The ASDM must be recalibrated by a Volvo dealership or a qualified auto glass shop that specializes in ADAS. This is not a DIY procedure as it requires specific targets and software. 🎬 Watch: A demonstration of the dynamic ASDM calibration procedure. A dealer may charge around $370 for the calibration service.
   Est. part cost: $0 (Labor cost is significant)
3. Damaged Windscreen or Faulty Heater Grid 🟡 Medium Probability The ASDM is highly sensitive to the optical quality of the glass it looks through. Volvo specifies that a stone chip as small as 0.5 x 3.0 mm in the sensor's line of sight can cause a fault. Owners have reported dealers quoting windscreen replacement for even minor chips in this area.
   How to confirm: Carefully inspect the glass in front of the ASDM for any chips, cracks, or deep scratches. If the fault only appears in cold, damp weather, the integrated windscreen heater grid that defrosts the sensor area may have failed. This can be tested with a multimeter by a technician.
   Typical fix: Volvo recommends against repairing chips in this critical area; the windscreen must be replaced. Following replacement, the ASDM must be recalibrated.
   Est. part cost: $800-$1500 (for OEM windscreen)
4. Software Incompatibility ⚪ Low Probability Affects 2019-2020 models specifically, as identified in a recall. The issue is caused by the ASDM microprocessor being unable to properly interpret temperature status from internal memory.
   How to confirm: A Volvo dealer can check the vehicle's service history against recall R29998 (NHTSA ID 20V-144). If the update has not been performed, this is a likely cause.
   Typical fix: The dealer must perform a software update on the Active Safety Domain Master (ASDM) module. This was a recall item and should be performed free of charge.
   Est. part cost: $0

Rare But Worth Checking

• Internal ASDM Failure: While rare, the camera/radar unit itself can fail electronically. This is usually the diagnosis after all other possibilities (obstruction, alignment, windscreen, software) have been ruled out. An owner of a 2018 XC90 reported a dealer quote of $2300 to replace the ASDM. Replacement and calibration are required.
• Low Battery Voltage: → Shop Vehicle Battery Modern Volvos are sensitive to battery health. A weak or failing 12V battery can cause sporadic and seemingly unrelated electronic faults, including issues with the ADAS modules. If other electronic glitches are present, or if the car is driven for short distances frequently, have the battery and charging system tested.

Diagnosis Steps

1. Read the code with an OBD-II scanner to confirm P2583 is present. For more detail, use a Volvo-specific scanner (VIDA) to check for suffix codes.
2. Thoroughly clean the exterior of the windscreen in front of the rearview mirror housing. Ensure there are no stickers, tags, or debris obstructing the sensor's view.
3. If the weather is cold or frosty, use the defroster for 10-15 minutes to ensure the integrated heater grid has cleared any ice from the sensor area.
4. Restart the vehicle. The code may clear on its own if the issue was a temporary obstruction.
5. Carefully inspect the glass in the sensor area for any chips, cracks, or scratches. Volvo states even very small damage can cause this fault.
6. If the windscreen has been recently replaced, or if the vehicle sustained a minor front-end impact, the cause is almost certainly a need for calibration.
7. Check vehicle history for NHTSA Recall 20V-144 (Volvo Recall R29998) if you have a 2019-2020 model. Ensure the software update has been performed.
8. If the above steps do not resolve the issue, the vehicle must be taken to a Volvo dealer or ADAS specialist for a diagnostic scan with Volvo-specific software (VIDA) to check for detailed fault codes, test the windscreen heater, and perform a sensor calibration.

Related Codes That Often Appear With This One

• ASDM-P2583xx — Volvo's specific diagnostic software (VIDA) will often show a more detailed suffix code along with the generic P2583, pointing to the exact nature of the fault (e.g., misalignment, blockage, internal failure). For example, P2583-73 can indicate an ASDM deactivation due to a fault.

Technical Service Bulletins (TSBs) & Recalls

• While no TSB is directly for P2583, Volvo Recall R29998 addresses a root cause (software) on 2019-2020 models.
• Volvo Technical Journals (TJs) are internal documents that provide repair hints. For example, TJ 34923 discusses issues related to the TCAM unit which can affect connectivity, while TJ 20803 addresses vibrations that could potentially lead to sensor misalignment over time.

Platform-Specific Known Issues

• NHTSA Recall 20V-144 (Volvo Recall R29998) was issued for 2019-2020 S60 models due to a software issue that could prevent the Automatic Emergency Braking system from functioning. The fix is a software update to the ASDM.

Mechanic-Grade Diagnostic Values

• CAN Bus Network Resistance — expected: Approximately 60 Ω (Ohms) when measured between CAN High (Pin 6) and CAN Low (Pin 14) at the OBD-II port with the battery disconnected.. Failure: A reading of ~120 Ω suggests one of the two terminating resistors (one is often in the ASDM) is offline or there's an open circuit. A reading near 0 Ω indicates a short between the CAN High and Low wires.
• CAN High Voltage (Key On, Engine Off) — expected: Approximately 2.6V to 2.7V, measured from CAN High (Pin 6 at OBD-II port) to chassis ground.. Failure: Significant deviation, 0V, or battery voltage points to a short to ground or power on the CAN High line.
• CAN Low Voltage (Key On, Engine Off) — expected: Approximately 2.3V to 2.4V, measured from CAN Low (Pin 14 at OBD-II port) to chassis ground.. Failure: Significant deviation, 0V, or battery voltage points to a short to ground or power on the CAN Low line.

Hidden / Shadow Codes Worth Checking

• P2583-76: Indicates the sensor is misaligned and requires aiming/calibration. This is a common suffix seen on other makes like Honda with the same base code. (see via Volvo VIDA or a professional-grade scanner with manufacturer-specific software.)
• B1A7F - Forward Looking Sensor Alignment: This code specifically indicates that the sensor requires calibration and often appears with P2583 after a windscreen replacement or physical jolt. (see via Volvo VIDA or compatible high-end scanner.)
• U016800 - Lost communication with Active Safety Domain Master: This code, set in other modules, indicates a complete communication breakdown with the ASDM. This points towards a power, ground, or CAN network fault rather than an internal ASDM issue. (see via Volvo VIDA or compatible high-end scanner.)

Scan Tool Commands That Help

• Volvo VIDA / compatible ADAS tool (Snap-on, Autel): ASDM - Radar and camera calibration — This function is mandatory after replacing the ASDM, replacing the windscreen, or if a code for missing calibration (like P2583-76 or B1A7F) is set. The procedure is a dynamic calibration, which requires initiating the function with the scan tool and then driving the vehicle for 5-15 minutes under specific conditions (e.g., on a well-marked road) to allow the system to self-align.

Wiring & Ground Locations

• OBD-II Port CAN Bus Pins — Inside the cabin, typically under the driver's side dashboard.. This is the primary access point for testing the integrity of the high-speed CAN bus network that the ASDM communicates on. Pin 6 is CAN High and Pin 14 is CAN Low.
• Chassis Grounds (e.g., 31/1, 31/2) — Various points in the engine bay (e.g., MacPherson strut towers) and cabin. Specific locations vary slightly by model year and require a wiring diagram to confirm.. A poor ground connection for the ASDM or related control modules can cause intermittent communication faults and trigger P2583. Verifying the integrity of the main chassis grounds is a crucial step in diagnosing network codes.

Real Owner Repair Stories

• OrBit Forums user 'bowditchsmith' (Volvo (model not specified, but SPA platform)) — "City Safety - Reduce functionality Service Required" message, ACC and Pilot Assist disabled.
  ❌ Tried (didn't work) The user had the windshield replaced by Safelite two months prior. The code appeared intermittently. The user attempted to clear the code and initiate calibration with an aftermarket tool (OrBit), which did not resolve the issue immediately.
  ✅ What actually fixed it The problem resolved itself after a drive cycle, suggesting an intermittent connection or a temporary condition that cleared. This highlights the sensitivity and potential for intermittent faults after windscreen service, even when calibration is performed.
• Volvo Owners Club Forum user 'NickRno77' (2019 Volvo S60 T5 R-Design) — After a windscreen replacement with a non-OEM screen, the Pilot Assist feature would not keep the car centered in the lane, always tracking to the right.
  ❌ Tried (didn't work) The windscreen company recalibrated the system twice with no improvement. They then replaced the aftermarket screen with a genuine Volvo screen, but the calibration still failed to fix the tracking issue.
  ✅ What actually fixed it The issue was unresolved in the thread, but the user suspected the windscreen company's calibration equipment was the problem. This story is a critical warning that even with OEM glass, faulty or incompatible calibration tools can prevent a successful repair.

OEM Part Supersession History

• Varies → Varies — Hardware/Software Revisions
  Heads up: When swapping used modules like the ASDM, Volvo's VIDA software may reject the part if the internal 'diagnostic part number' does not match what is expected for the vehicle's configuration, even if the hardware part number is a known supersession. This can prevent software loading and programming, making the used part unusable.

Model Year Variations Within This Range

• 2019-2020: These model years were subject to NHTSA Recall 20V-144 (Volvo Recall R29998) for a software bug in the ASDM that could disable the automatic emergency braking system. The fix is a dealer-installed software update.
• 2019-2024: All vehicles in this range utilize Diagnostics over IP (DoIP) Ethernet protocols for module communication. This requires a modern scan tool compatible with DoIP; older professional scan tools may not be able to communicate with modules like the ASDM.

Other Known Issues on This Vehicle

Issues unrelated to this code that are worth knowing about as an owner of this generation:

• Sensus Infotainment System Glitches 🟠 Medium — Commonly reported issue involving screen freezing, black screens, or Bluetooth connectivity problems. Often resolved with a system reset (holding the home button) or a software update from the dealer.
• Premature Brake Wear 🟠 Medium — Owners on forums frequently report faster-than-expected wear on brake pads and rotors, sometimes accompanied by brake judder.
• 12V Battery Drain / Charging Faults 🟠 Medium → Shop Vehicle Battery — Particularly on mild-hybrid models, owners report '12V battery critical charging fault' warnings. This can be caused by software issues (especially on 2022 models), frequent short trips, or the car not entering 'sleep' mode correctly.
• Plug-In Hybrid (PHEV) High-Voltage Battery Issues 🔴 High → Shop Vehicle Battery — Affects 2020-2022 PHEV models. A recall was issued for potential short-circuits in the high-voltage battery when fully charged. A subsequent software update to monitor battery cells more sensitively has led to some owners needing cell or full battery pack replacements. (Ref: Volvo Recall (specific number varies, related to NHTSA campaign in early 2025))
• Passenger Airbag Improperly Torqued 🔴 High — A recall (R10254 / NHTSA 23V-780) was issued for 2019-2024 models because passenger airbag retaining screws may not have been torqued correctly at the factory, potentially affecting deployment. (Ref: R10254 / NHTSA 23V-780)

Used vs. New Parts: Buying Guide for This Vehicle

When a used part is the smart pick: A used ASDM module is a high-risk, last-resort option to save on the high cost of a new unit. It should only be considered if you have access to a specialist who can confirm compatibility and has the tools to potentially 'unlock' and program a used module, as dealers will refuse this service.

Donor-vehicle mileage cap: roughly under 50000 miles for the part to have meaningful remaining life.

What to inspect on the donor part:

• Verify the part number is an EXACT match to the original unit.
• Inspect the lens for any scratches, delamination, or cloudiness.
• Ensure connector pins are straight, clean, and free of any corrosion.
• Obtain the VIN of the donor car to check its history for front-end collisions.

OEM-only on this vehicle (don't cheap out):

• Active Safety Domain Master (ASDM): Due to software locks, VIN programming, and safety-critical calibration, a new OEM part from a dealer is the only guaranteed path to a working repair.
• Windscreen: While aftermarket glass exists, numerous owner reports indicate that only genuine Volvo (or OEM-supplier like Pilkington) glass has the correct optical clarity to ensure successful ADAS calibration. Using non-OEM glass is a common cause of persistent calibration failures.

Brands owners have reported issues with on this vehicle:

• Non-OEM windscreens: Brands not supplying Volvo directly have been reported to cause issues where Pilot Assist will not track correctly even after multiple calibration attempts.
