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 will result in false resistance readings. Refer to
BATTERY, MOUNTING AND CABLES
.
- AF1 CHECK THE MESSAGE CENTER OPERATION
- Close all doors, hood and liftgate.
- Ignition ON.
- Open the driver door while monitoring the message center displays.
- Does the message center display DRIVER DOOR AJAR?
- Yes : GO to AF2.
- No : GO to PINPOINT TEST X .
- AF2 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST
- Check for recorded DTCs from the IPC self-test.
- Is DTC U0214:00 recorded?
- Yes : GO to PINPOINT TEST AZ .
- No
: If the SHIFT TO PARK message is always on, GO to AF3.
If the SHIFT TO PARK message in inoperative, GO to AF5.
- AF3 CHECK THE PARK DETECT INPUT TO THE RFA MODULE
- Ignition OFF.
- Disconnect: Selector Lever C3245.
- Monitor the SHIFT TO PARK message in the message center.
- Does the SHIFT TO PARK message turn off?
- Yes : INSTALL a new selector lever. REFER to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS . TEST the system for normal operation.
- No : GO to AF4.
- AF4 CHECK THE PARK INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: RFA Module C2153D.
- Measure the resistance between the RFA module C2153D-20, circuit CDC41 (WH/BN), harness side and ground.
- Is the resistance greater than 10, 000 ohms?
- Yes : GO to AF7.
- No : REPAIR circuit CDC41 (WH/BN) for a short to ground. TEST the system for normal operation.
- AF5 CHECK THE SELECTOR LEVER OPERATION
- Ignition OFF.
- Disconnect: Selector Lever C3245.
- Connect a fused jumper wire between the selector lever C3245-2, circuit CDC41 (WH/BN), harness side and ground.
- Ignition ON.
- Monitor the SHIFT TO PARK message in the message center.
- Does the SHIFT TO PARK message turn on?
- Yes : INSTALL a new selector lever. REFER to AUTOMATIC TRANSAXLE/TRANSMISSION EXTERNAL CONTROLS . TEST the system for normal operation.
- No : LEAVE the jumper wire connected. GO to AF6.
- AF6 CHECK THE SELECTOR LEVER INPUT CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect: Negative Battery Cable.
- Disconnect: RFA Module C2153D.
- Measure the resistance between the RFA module C2153D-20, circuit CDC41 (WH/BN), harness side and ground.
- Is the resistance less than 5 ohms?
- Yes : GO to AF7.
- No : REPAIR circuit CDC41 (WH/BN) for an open. TEST the system for normal operation.
- AF7 CHECK FOR CORRECT RFA MODULE OPERATION
- Disconnect the RFA module connectors.
- Check for:
- corrosion
- damaged pins
- pushed-out pins
- Connect the RFA module connectors and make sure they seat correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new RFA module. REFER to MULTIFUNCTION ELECTRONIC MODULES . 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.
