U3017 on 2022-2024 Ram 1500: Control Module Timer/Clock Performance Explained

What's Unique About the 2022-2024 Ram 1500

For the 2022-2024 Ram 1500, this code is particularly relevant for models equipped with the eTorque mild-hybrid system. The provided NHTSA Technical Service Bulletin #08-033-24 specifically lists U3017 and targets the Battery Pack Control Module (BPCM) on 2022 models with the 3.6L eTorque V6 and 5.7L eTorque V8 engines. A subsequent TSB, #08-034-24, extends this same issue and software update fix to 2023 models. This indicates the fault is often tied to the complex electronics managing the hybrid system, making a software update from the manufacturer the most probable solution.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Check Engine Light (Malfunction Indicator Lamp) is on.
• Error messages on the instrument cluster, possibly related to the hybrid system or start/stop functionality.
• Potential issues with the automatic start/stop system functionality.
• Loss of time/date on the infotainment screen or other timed convenience features resetting.

Most Likely Causes

1. Control Module Software Anomaly 🔴 High Probability Manufacturers frequently release software updates to fix overly sensitive diagnostic logic. TSB #08-033-24 (for 2022) and #08-034-24 (for 2023) explicitly state the cause for U3017 (and other codes) on eTorque models is the BPCM Software and the repair is to update it. This is a historically common issue, with owners of previous generation Rams also reporting that dealers had to wait for software updates to be released.
   How to confirm: A Ram dealership or a qualified independent shop can use a diagnostic tool (like wiTECH) to check for available software updates for the Battery Pack Control Module (BPCM), PCM, or BCM by referencing the vehicle's VIN.
   Typical fix: Reprogramming the affected control module with the latest manufacturer software. TSB #08-033-24 specifies a labor time of 0.2 hours for this task.
   Est. part cost: $0-$250
2. Weak or Failing 12V Battery 🟡 Medium Probability → Shop Vehicle Battery Low system voltage during startup, shutdown, or even from leaving the ignition in the accessory position for an extended time can cause modules to lose their timer memory or report performance issues. This can happen before the battery is weak enough to cause a no-start condition. The diagnostic procedure often checks for P2509 (PCM Power Input Signal Intermittent) as a related code pointing to a battery issue.
   How to confirm: Perform a professional load test on the 12V battery. A simple voltage check is often not sufficient. Resting voltage should be above 12.4V, and cranking voltage should remain above 11V. The dealer procedure for the TSB requires connecting a battery charger to ensure voltage does not drop below 13.2 volts during the reflash, highlighting the system's sensitivity.
   Typical fix: Replace the vehicle's 12V AGM battery.
   Est. part cost: $200-$400
3. Faulty Control Module ⚪ Low Probability While less common than a software bug, the module's internal real-time clock (RTC) can fail. TSB #08-033-24 for the hybrid system lists U3017 alongside other codes that could point to a module failure, but identifies the software as the primary cause to be addressed first. Service documents for similar issues explicitly advise against replacing modules for this code until all other possibilities are exhausted.
   How to confirm: This is a diagnosis of exclusion. If the BPCM/PCM software update has been performed, the 12V battery is confirmed to be healthy, and the code still returns, the module itself is suspect. This is the last step after all other, more probable causes are eliminated.
   Typical fix: Replace the faulty control module (e.g., Hybrid Control Processor/BPCM, PCM, or BCM) and program the new unit to the vehicle.
   Est. part cost: $500-$1500

Rare But Worth Checking

• Recent Coolant System Service: The diagnostic logic for this code on some Ram trucks uses the rate of coolant temperature drop to verify the ignition-off timer. If air was introduced into the system during a recent coolant change, it could cause an erratic temperature reading and falsely trigger the code. The official diagnostic tree sometimes involves checking the coolant temperature sensor.
• Recent Module Reprogramming or Reconfiguration: The code can be falsely set immediately after a module is reprogrammed or if the vehicle is changed from 'Shipping Mode' to 'Customer Mode' during dealer prep, as the timer value can be lost in the process. If the code appears right after a dealer service, this could be the cause.

Diagnosis Steps

1. Check for Technical Service Bulletins (TSBs): This is the most critical first step. Contact a Ram dealer with your VIN to see if TSB #08-033-24 (2022 models) or TSB #08-034-24 (2023 models) or any other software update applies.
2. Scan for All Codes: Use a quality OBD-II scanner to read all stored codes. Pay close attention to any other codes listed in the TSBs, or code P2509, which points toward a battery issue.
3. Test the 12V Battery and Charging System: Have the 12V battery professionally load-tested. Ensure terminals are clean and tight. A simple voltage check is not enough. The system is highly sensitive to voltage drops.
4. Apply Software Updates: If a TSB is available, have the dealer perform the software reflash. The TSBs involve updating the Battery Pack Control Module (BPCM) and are the prescribed fix.
5. Clear Codes and Monitor: After performing any updates or repairs, clear all DTCs. Some scanners may report the code as 'permanent' and be unable to clear it; a specific drive cycle may be required. Drive the vehicle through several key cycles (turning it on and off, allowing it to sit for at least 30 minutes) to see if the code returns.
6. Diagnose the Control Module: If the code persists after a software update and battery check, a professional will need to diagnose the specific module that is setting the code, which may involve checking power, ground, and network connections before condemning the module.

Technical Service Bulletins (TSBs) & Recalls

• Bulletin #08-033-24: Titled 'Battery Pack Control Module (BPCM) Software Update', dated Jan 30, 2024.
• Bulletin #08-034-24: Titled 'Battery Pack Control Module (BPCM) Software Update', dated Jan 30, 2024.

Platform-Specific Known Issues

• TSB for 2022 eTorque Models: TSB #08-033-24 specifically links code U3017 to the hybrid propulsion system on 2022 models with either the 3.6L or 5.7L eTorque engine. The fix is a software update to the Battery Pack Control Module (BPCM).
• TSB for 2023 eTorque Models: TSB #08-034-24 extends the same software issue and BPCM update fix to 2023 Ram 1500 models with the eTorque engines, confirming the problem was not limited to the 2022 model year.

Mechanic-Grade Diagnostic Values

• Diagnostic Monitor Run Conditions — expected: The diagnostic runs if a minimum 10°C (18°F) coolant temperature drop occurred since the last key-off, and the engine temp at the previous shutdown was at or above 76.6°C (169.8°F).. Failure: If these conditions are met and the BCM's reported ignition-off time doesn't match the expected time from coolant temp drop, the code is set.
• Battery Voltage at Module Connector (Key-On-Engine-Off) — expected: 12.4V - 12.8V. Failure: Voltage below 12.4V indicates a discharged or failing battery that can cause module memory loss.
• Ground Strap/Connection Resistance — expected: Under 0.1 Ω. Failure: Higher resistance indicates a poor ground connection, which can cause intermittent module power and logic issues.
• Parasitic Draw (after modules enter sleep mode) — expected: < 25 milliamps (mA). Failure: A higher reading indicates a component is not shutting down correctly, which can drain the battery and cause low voltage conditions that trigger U3017.
• Alternator Charging Voltage (during reflash) — expected: 13.2V - 13.5V. Failure: Voltage dropping below this range during a software update can cause the reflash to fail or corrupt the module.

Hidden / Shadow Codes Worth Checking

• Permanent DTC (P-DTC): U3017 can be stored as a 'Permanent' Diagnostic Trouble Code. This means it cannot be cleared by a standard 'Clear Codes' command from most OBD-II scanners, even after the underlying fault is fixed. The code is only cleared by the control module itself after it has run and passed the specific self-test diagnostic multiple times under the required conditions (drive cycle). (see via A standard OBD-II scanner will show the code but may give an error when attempting to erase it. Dealer-level tools like wiTECH may have a specific function to clear these codes after a repair is verified.)

Scan Tool Commands That Help

• wiTECH (Dealer Tool): Reprogram BPCM — This is the primary repair step specified in TSBs #08-033-24 and #08-034-24 to fix the software anomaly causing code U3017 on eTorque models.
• wiTECH (Dealer Tool): Change Shipping Mode to Customer Mode — This function is used during new vehicle preparation. Diagnostic notes state that performing this action can inadvertently set code U3017 because it can reset the BCM's ignition-off timer. This is more for understanding a potential cause rather than a diagnostic test.
• wiTECH, AlfaOBD, or equivalent: Clear All Faults — Used after a repair (like a battery replacement or software flash) to erase the stored U3017 code. Note that if the code is stored as a Permanent DTC, this may not be successful until a proper drive cycle is completed.

Wiring & Ground Locations

• Body Control Module (BCM) — Located deep under the driver's side dashboard, high up and difficult to access. It is held in by several bolts and has multiple large electrical connectors.. This is one of the primary modules that can set this code. A poor connection at one of its main connectors could cause timer performance issues, although this is less likely than a software or battery fault.
• Main Engine/Body Ground Strap — While there are many grounds, a key grounding point is often located on the passenger side inner fender/wheel well area, near the alternator.. A poor ground can cause voltage irregularities across the vehicle's electrical system, leading to unpredictable behavior in sensitive control modules and potentially triggering timer-related fault codes like U3017.

Real Owner Repair Stories

• Turbo Diesel Register forum user (2014 Ram (demonstrates a common trigger)) — Check Engine Light with code U3017, which was reported as a 'permanent' code by the scanner. A low system voltage code was also pending.
  ❌ Tried (didn't work) A simple code clear was unsuccessful because the code was stored as permanent.
  ✅ What actually fixed it The user identified the cause as leaving the key in the accessory position for an extended period, which drained the battery. After recharging the battery, the issue was resolved, confirming that low voltage is a direct cause.
• RamForum.com user (Ram 1500 (generation not specified)) — Check Engine Light came on with no other symptoms; code reader showed only U3017.
  ❌ Tried (didn't work) N/A
  ✅ What actually fixed it The user cleared the code with a handheld scanner, and it did not return after several drive cycles. This indicates the code can sometimes be a one-time, random glitch that does not require a repair.

OEM Part Supersession History

• P68434932AA → No definitive supersession data found in public sources. — N/A
  Heads up: When replacing a BPCM or HCP, the part number must exactly match the original, or be a dealer-confirmed superseded part number. The new module will require VIN programming with a tool like wiTECH to function.

Model Year Variations Within This Range

• 2022 vs 2023: The software issue in the Battery Pack Control Module (BPCM) on eTorque models that can cause U3017 is not isolated to 2022 vehicles. TSB #08-033-24 addresses 2022 models, while TSB #08-034-24, released on the same date, addresses the exact same list of DTCs, including U3017, for 2023 models. The fix for both is a BPCM software update.
