B2417 on 2015-2016 Nissan Murano: Power Liftgate Touch Sensor Fault Guide

What's Unique About the 2015-2016 Nissan MURANO

The third-generation (Z52) Nissan Murano uses touch-sensitive switches on the liftgate for hands-free operation. These sensors and their wiring are located in the liftgate itself, making them susceptible to moisture intrusion, physical damage, and wire fatigue. The wiring harness that passes from the body to the liftgate through a flexible rubber boot is a known weak point, where repeated opening and closing can cause wires to break. Nissan has issued Technical Service Bulletins (TSBs) related to the automatic back door system, indicating this is a recognized issue.

Diagnostic Flowchart

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

Symptoms You May Notice

• The power liftgate will not open or close when using the left-side exterior touch sensor/button.
• The entire automatic back door system may become inoperative.
• A warning chime or message may appear on the instrument cluster.
• Intermittent operation of the touch sensor before complete failure.
• A series of beeps (often three) when attempting to use the power liftgate, with no movement.

Most Likely Causes

1. Electronic Glitch / Low Battery Voltage 🔴 High Probability The Automatic Back Door Control Module (ABD CU) is sensitive to low voltage from the vehicle's main battery. A weak battery, or even a temporary voltage drop, can cause the module to enter a fault state and stop responding.
   How to confirm: This is the easiest potential cause to check. First, test the vehicle's battery to ensure it is healthy. If the battery is good, a system reset is the next step.
   Typical fix: Perform a hard reset of the liftgate control module. Disconnect the negative terminal of the vehicle's 12V battery for 10-15 minutes, then reconnect it. This forces the module to reboot and often clears the fault without any parts replacement.
   Est. part cost: $0
2. Failed Left Touch Sensor 🔴 High Probability The sensor is exposed to weather elements and physical contact, leading to wear and internal failure over time. Water intrusion is a common cause of failure.
   How to confirm: After accessing the sensor by removing the liftgate's interior trim, test the sensor's circuit for an 'open' condition using a multimeter. An infinite resistance reading (OL) indicates a failed sensor. A known good sensor may show some resistance.
   Typical fix: Replace the left-side touch sensor assembly. The part is often called 'Sensor-Touch, Power Back LH'.
   Est. part cost: $150-$250
3. Damaged Wiring or Connector 🟡 Medium Probability The wiring harness that runs from the vehicle body to the liftgate passes through a flexible rubber boot near the top hinge. Repeated opening and closing of the liftgate causes these wires to fatigue and break over time, creating an open circuit.
   How to confirm: Visually inspect the wiring harness for breaks, chafing, or pinch points, paying close attention to the section inside the rubber boot. Pull gently on the wires to see if any are broken internally. Perform a continuity test on the wires leading from the ABD CU to the left touch sensor.
   Typical fix: Repair the broken wire(s) with a new section of wire and butt connectors or solder, then protect the repair with heat shrink tubing.
   Est. part cost: $5-$20
4. Software Glitch / Need for Reprogramming ⚪ Low Probability Nissan TSBs mention that the Automatic Back Door Control Module may require reprogramming to resolve operational issues, especially on 2015 models. This is less common than a simple electronic glitch fixed by a battery reset.
   How to confirm: This is difficult to confirm without a dealer-level scan tool (CONSULT). This is typically suspected after the sensor, wiring, and battery reset have all failed to resolve the issue.
   Typical fix: A Nissan dealership or a qualified shop with a CONSULT scan tool must reprogram the ABD CU and perform a calibration as per TSB NTB15-073B.
   Est. part cost: $0 (if under warranty) or shop labor cost for reprogramming

Rare But Worth Checking

• Failed Automatic Back Door Control Module (ABD CU): → Shop Body Control Module While the module is what stores the code, it is the least likely component to fail. All other potential causes, such as the sensor, wiring, and a system reset, should be thoroughly ruled out before considering module replacement. A user on Reddit reported replacing the module on a similar Nissan Rogue with no success, pointing to other root causes.

Diagnosis Steps

1. Verify the presence of code B2417 using an OBD-II scanner capable of reading B-codes (Body codes).
2. Perform a System Reset First: Disconnect the negative terminal of the vehicle's 12V battery for 10-15 minutes. Reconnect and test liftgate operation. Many electronic glitches are resolved with this step.
3. As recommended by Nissan TSB NTB15-073B, check the vehicle's battery voltage with the engine off. Ensure it is stable and above 12.0V. 🎬 See these common liftgate repairs and diagnostic checks A weak battery is a known cause of liftgate system faults.
4. Attempt to operate the liftgate using all available methods: the right-side touch sensor, the interior dash button, and the key fob. This helps confirm the fault is isolated to the left sensor circuit.
5. Pull back the rubber boot/grommet between the liftgate and the vehicle body. Carefully inspect the wiring harness inside for any visible breaks, cracks, or chafed wires. Gently tug on each wire to check for internal breaks.
6. Remove the interior trim panel from the liftgate to gain access to the touch sensor and its wiring. This typically involves removing several push-pins and a handle cover.
7. Visually inspect the connector for the left touch sensor for any signs of corrosion, moisture, or loose pins. Disconnect and reconnect it to ensure a solid connection.
8. Using a multimeter set to continuity or resistance mode, test the wires running from the sensor's connector to the Automatic Back Door Control Module to rule out a broken wire if one was not found at the hinge.
9. If the wiring is confirmed to be good and the system reset did not work, the fault most likely lies with the touch sensor itself. Replace the left touch sensor.
10. If the issue persists after replacing the sensor and verifying the wiring, the problem may require a software update or calibration by a Nissan dealer per TSB NTB15-073B.

Parts You'll Likely Need

• Power Back Door Touch Sensor (Left) (OEM #90569-5AA0A, superseded by 90569-5AA0B) — This is the component that the code directly identifies as having an 'open' circuit. It is the most common point of failure for this specific code after ruling out electronic glitches.
  Trusted brands: Nissan (OEM)
  OEM price range: $215-$250
  Aftermarket price range: N/A

Related Codes That Often Appear With This One

• B2416-1E — This is the code for 'TOUCH SEN R OPEN' (Right Touch Sensor Open). It's common to see both sensor codes if there is a shared wiring or module issue.
• B2426-29 / B2427-29 — These codes for 'SPINDLE SENSOR LH' and 'SPINDLE SENSOR RH' relate to the power strut motors. They can appear alongside B2417 if the entire back door system is malfunctioning.
• B242A-13 — This code for 'CLSR CONDITION' (Closer Condition) is also part of the automatic back door system and is listed in the same TSBs as B2417.

Technical Service Bulletins (TSBs) & Recalls

• NTB15-073B: Lists B2417-1E 'TOUCH SEN L OPEN' as a stored DTC when the automatic back door is inoperative on 2015-2016 Murano.

Platform-Specific Known Issues

• Nissan Technical Service Bulletin NTB15-073B (and its revisions) directly addresses the condition where the automatic back door does not operate and lists DTC B2417-1E 'TOUCH SEN L OPEN' as a primary cause. The bulletin guides technicians to check battery voltage and, for 2015 models, potentially reprogram the control module.
• Owner communities strongly suggest that before any disassembly or parts are ordered, a simple hard reset by disconnecting the 12V battery for 10-15 minutes should be performed, as this frequently resolves electronic glitches in the liftgate control module.

Mechanic-Grade Diagnostic Values

• Voltage at ABD CU Connector B69, Pin 7 (Left Touch Sensor Signal) to Ground — expected: Approximately 0V with sensor untouched, rising to approximately 5V when the sensor is touched.. Failure: A constant 5V reading or a reading that does not change when the sensor is touched indicates a fault in the sensor or wiring.

Scan Tool Commands That Help

• Nissan CONSULT III Plus: Data Monitor for 'AUTO BACK DOOR' system — Use this to observe the live status of the 'TOUCH SENSOR LH'. The on-screen value should change from 'OFF' to 'ON' when the exterior liftgate sensor is touched. This provides a definitive, real-time confirmation of whether the sensor and its circuit are communicating with the control module, bypassing the need for manual voltage checks if the tool is available.
• Nissan CONSULT III Plus: Reprogram ABD CU — This is used specifically on 2015 Murano models as per TSB NTB15-073B if the control module part number is 284G3-5AA0A. It updates the module's software to correct operational faults.

Wiring & Ground Locations

• Automatic Back Door (ABD) Control Unit — Located in the rear left of the vehicle, behind the cargo area side trim panel.. This module is the brain for the power liftgate system. It's where the B2417 code is stored and where diagnostic voltage and continuity tests must originate or terminate.
• ABD CU Connector B69, Pin 7 — On the main connector for the Automatic Back Door Control Unit.. This is the specific pin for the signal wire from the left touch sensor. Testing voltage here is a primary diagnostic step to confirm if the signal is reaching the module.
• ABD CU Connector B69, Pin 8 — On the main connector for the Automatic Back Door Control Unit.. This is the sensor ground wire. A continuity check between this pin and the sensor connector is necessary to rule out a break in the ground side of the circuit.
• Liftgate Wiring Harness Boot — The flexible rubber boot located at the top of the liftgate, connecting the liftgate wiring to the main body harness.. This is the most common location for wire fatigue and breakage due to the repeated motion of opening and closing the liftgate. A visual inspection and continuity test of the wires inside this boot is critical.

Real Owner Repair Stories

• NissanMurano.org forum user (2015 Nissan Murano) — Power liftgate would not operate using the exterior buttons, triggering codes B2417 and B2416.
  ❌ Tried (didn't work) Disconnecting the battery to reset the system., Inspecting the wiring harness in the rubber boot between the body and liftgate (no visible breaks found).
  ✅ What actually fixed it The owner replaced both the left and right exterior touch sensors (part number 90569-5AA0A). After replacing the sensors, the codes were cleared and the power liftgate function was fully restored.

When the Usual Fixes Don't Work

• While a simple battery disconnect is the most commonly recommended first step and often resolves the issue, there are multiple owner-confirmed repairs where this procedure did not work. In these cases, the fault was persistent and required physical replacement of the failed touch sensor to resolve the B2417 code and restore liftgate function.

OEM Part Supersession History

• 90569-5AA0A → 90569-5AA0B — The reason is not officially stated, but part revisions for external electronic components are commonly made to improve durability and resistance to weather and moisture intrusion.
  Heads up: The parts are interchangeable; 90569-5AA0B is the correct replacement for 90569-5AA0A.

Model Year Variations Within This Range

• 2015 only: Technical Service Bulletin NTB15-073B specifies that only 2015 Murano models may require the Automatic Back Door Control Unit (ABD CU) to be reprogrammed. If the installed ABD CU has part number 284G3-5AA0A, it must be updated with a CONSULT scan tool. Later models or 2015s with a different part number do not require this specific reprogramming step for this issue.
