Diagnostic Procedure

DTC B1495:55 [POWER LIFTGATE (PLG) CONTROL MODULE] DIAGNOSTIC PROCEDURE

Step Inspection Action
1 VERIFY IF OTHER DTCs DISPLAYED FOR POWER LIFTGATE (PLG) CONTROL MODULE Yes Replace the power liftgate (PLG) control module, then go to step 7.
(See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION .)
No Go to the next step.
2 VERIFY INSTRUMENT CLUSTER DTCs Yes Repair the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [INSTRUMENT CLUSTER] .)
No Go to the next step.
3 INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR SHORT TO GROUND Yes Refer to appropriate wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
If there is a common connector:
  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.
  • Repair or replace the malfunctioning part.

If there is no common connector:
  • Repair or replace the wiring harness which has a short to ground.

Go to Step 7.
No Go to the next step.
4 INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR SHORT TO POWER SUPPLY
  • Verify that the foot-motion detection unit and power liftgate (PLG) control module connectors are disconnected.
  • Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
  • Switch the ignition ON (engine off or on).
  • Measure the voltage at the following foot-motion detection unit terminal 1C (wiring harness-side).
  • Is the voltage 0V?
Yes Go to next step.
No Refer to appropriate wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
If there is a common connector:
  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.
  • Repair or replace the malfunctioning part.

If there is no common connector:
  • Repair or replace the wiring harness which has a short to power supply.

Go to Step 7.
5 INSPECT FOOT-MOTION DETECTION UNIT CIRCUIT FOR OPEN CIRCUIT
  • Switch the ignition off.
  • Disconnect the negative battery terminal.

    (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)

  • Verify that the foot-motion detection unit and power liftgate (PLG) control module connectors are disconnected.
  • Inspect for continuity between the following foot-motion detection unit terminal 1C (wiring harness-side) and power liftgate (PLG) control module terminal 1C (wiring harness-side).
  • Is there continuity?
Yes Go to the next step.
No Refer to appropriate wiring diagram and verify whether or not there is a common connector between foot-motion detection unit terminal 1C and power liftgate (PLG) control module terminal 1C.
If there is a common connector:
  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.
  • Repair or replace the malfunctioning part.

If there is no common connector:
  • Repair or replace the wiring harness which has an open circuit.

Go to Step 7.
6 RESET INSTRUMENT CLUSTER CONFIGURATION DATA Yes Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step.
(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA) .)
No Go to Step 9.
7 VERIFY IF MALFUNCTIONING LOCATION IS FOOT-MOTION DETECTION UNIT DEPENDING ON REPEATABILITY Yes Replace the foot-motion detection unit, then go to the next step.
(See FOOT-MOTION DETECTION UNIT REMOVAL/INSTALLATION .)
No Go to Step 9.
8 VERIFY THAT REPAIRS HAVE BEEN COMPLETED Yes Replace the power liftgate (PLG) control module, then go to the next step.
(See POWER LIFTGATE (PLG) CONTROL MODULE REMOVAL/INSTALLATION .)
No Go to the next step.
9 VERIFY IF OTHER DTCs DISPLAYED
  • Are any other DTCs displayed?
Yes Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [POWER LIFTGATE (PLG) CONTROL MODULE] .)
No DTC troubleshooting completed.
