Pinpoint Test AA: Easy Exit/Easy Entry is Inoperative/Does Not Operate Correctly
Normal Operation
The Driver Seat Module (DSM) receives a key out command over the Medium Speed Controller Area Network (MS-CAN) communication network and powers the driver seat rearward about 51 mm (2 in).
This pinpoint test is intended to diagnose the following:
- Easy entry/exit feature is not enabled
- Missing status information (Controller Area Network (CAN) communication bus messages) to the DSM:
- ignition status
- gear selector position
- Wiring, terminals or connectors
- Faulty key-in-ignition warning switch
- Faulty DSM
PINPOINT TEST AA: EASY EXIT/EASY ENTRY IS INOPERATIVE/DOES NOT OPERATE CORRECTLY
NOTICE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. Inspection and Verification
NOTE: Verify good battery condition before diagnosing the memory seat system. Poor battery condition may interfere with memory seat operation, even if vehicle starting is possible.
NOTE: The transmission gear selector must be in PARK and the driver seat must be at least 51 mm (2 in) from its rear stopping point for the easy entry/exit feature to function.
NOTE: The DSM monitors ignition switch and transmission gear selector position status messages communicated across the CAN. This information is required for correct memory seat operation. Ignition switch and transmission gear selector status should be verified by using a scan tool to monitor the available PID data before proceeding with memory seat diagnosis.
NOTE: The Smart Junction Box (SJB) may also be identified as Generic Electronic Module (GEM).
NOTE: If a new DSM is installed, the driver seat, memory mirrors and power adjustable pedals (if equipped) must be operated in all directions through the full range of travel to avoid a premature stopping point occurrence after the vehicle is returned to the customer.
-------------------------------------------------
AA1 CHECK FOR EASY ENTRY FEATURE ENABLE AND DRIVER POWER SEAT OPERATION
- Ignition ON.
- Check the message center to verify the EASY ENTRY feature is enabled.
- Select the EASY ENTRY feature using the SETUP button.
- If enabled, '(ON)' should be displayed. If not, select (ON) using the RESET button.
- Operate the driver power seat operates fully forward and rearward.
- Is the EASY ENTRY feature enabled and the seat operating horizontally using the seat control switch?
Yes
RE-POSITION the seat at least 51 mm (2 in) from its rear stopping point and GO to AA2.
No
If disabled, ENABLE the easy entry/exit feature. TEST the system for normal operation. If OK, INSTRUCT the customer on correct feature operation.
If the seat does not move horizontally using the seat control switch, Go To Pinpoint Test K. Pinpoint Test K: The Memory Seat Is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically/Recline
-------------------------------------------------
AA2 CHECK THE DSM FOR DTCs
- Enter the following diagnostic mode on the scan tool: Self Test - DSM.
- Are any DSM DTCs retrieved?
Yes
REFER to the Driver Seat Module (DSM) DTC Chart.
No
GO to AA3.
-------------------------------------------------
AA3 CHECK THE TR PID
- Enter the following diagnostic mode on the scan tool: DataLogger - PCM PID - TR.
- Monitor the PCM PID TR value with the transmission gear selector in PARK.
- Does the PID state agree with the selected transmission gear PARK position?
Yes
GO to AA4.
No
To diagnose a transmission gear selector status concern, REFER to Transmission Control Systems. Testing and Inspection
-------------------------------------------------
AA4 CHECK THE IGNITION SWITCH POSITION (IGN_SW) PID
- Enter the following diagnostic mode on the scan tool: DataLogger - GEM SJB PIDs.
- Monitor the GEM SJB PID IGN_SW with the key in and out of the ignition switch.
- Does the PID agree with the key positions (KEY IN and KEY OUT)?
Yes
INSTALL a new DSM and CARRY OUT Programmable Module Installation (PMI). Programming and Relearning REPEAT the self-test. CLEAR the DTCs.
No
To diagnose the key-in-ignition warning switch fault, REFER to Instrument Panel, Gauges and Warning Indicators.
