Pinpoint Test Ag: The Vehicle Not In Park Select P Message Is Inoperative/Always On (IA Only)
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
NOTE:
Failure to disconnect the battery when instructed results in false resistance readings. Refer to BATTERY, BATTERY MOUNTING & BATTERY CABLES
.
- AG1 CHECK THE PARK DETECT INPUT TO THE IPC
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC DataLogger.
- Select the IPC park detect PID (GEAR_PARK).
- Monitor the PID while moving the floor shifter in and out of PARK (P).
- Does the PID display TRUE when in PARK (P) and FALSE when out of PARK (P)?
- Yes : GO to AG2.
- No : GO to AG3.
- AG2 RETRIEVE THE RECORDED DTCs FROM THE FCDIM SELF-TEST
- Check for recorded DTCs from the FCDIM self-test.
- Is DTC U0155:00 recorded?
- Yes : REFER to INFORMATION & ENTERTAINMENT SYSTEMS .
- No : INSTALL a new FCDIM. REFER to INFORMATION & ENTERTAINMENT SYSTEMS . TEST the system for normal operation.
- AG3 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST
- Check for recorded DTCs from the IPC self-test.
- Are any DTCs recorded?
- Yes
: For DTC P081C:01, GO to AG4.
For all other DTCs, REFER to DTC CHARTS .
- No : GO to AG6.
- AG4 CHECK THE PARK DETECT INPUT CIRCUIT FOR A SHORT TO VOLTAGE
- Ignition OFF.
- Disconnect: IPC C220.
- Disconnect: Remote Function Actuator (RFA) Module C3503C.
- Ignition ON.
- Measure the voltage between the IPC C220-25, circuit CDC41 (WH/BN), harness side and ground.
- Is any voltage present?
- Yes : REPAIR circuit CDC41 (WH/BN) for a short to voltage. TEST the system for normal operation.
- No : GO to AG5.
- AG5 CHECK THE PARK DETECT INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: Floor Shifter C3245.
- Measure the resistance between the IPC C220-25, circuit CDC41 (WH/BN), harness side and the floor shifter C3245-2, circuit CDC41 (WH/BN), harness side.
- Is the resistance less than 5 ohms?
- Yes : GO to AG7.
- No : REPAIR circuit CDC41 (WH/BN) for an open. TEST the system for normal operation.
- AG6 CHECK THE PARK DETECT INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: Remote Function Actuator (RFA) Module C3503C.
- Measure the resistance between the IPC C220-25, circuit CDC41 (WH/BN), harness side and ground.
- Is the resistance greater than 10, 000 ohms?
- Yes : GO to AG7.
- No : REPAIR circuit CDC41 (WH/BN) for a short to ground. TEST the system for normal operation.
- AG7 CHECK FOR CORRECT IPC OPERATION
- Disconnect the IPC connector.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the IPC connector and make sure it seats correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new IPC. REFER to INSTRUMENT PANEL CLUSTER (IPC) . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
