Pinpoint Test L: 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 (Driver Seat Module) :
- ignition switch status

- gear selector position


- Wiring, terminals or connectors

- Key-in-ignition switch

- DSM (Driver Seat Module)

PINPOINT TEST L : 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 DSM (Driver Seat Module) monitors ignition switch and transmission gear selector position status messages communicated across the CAN (Controller Area Network). 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 (Driver Seat Module) is installed, the driver seat 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.

L1 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.


- Using the seat control switch, verify 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 L2.

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 Does Not Operate Correctly - Does Not Operate Using the Memory SET Switch

L2 CHECK THE DSM (Driver Seat Module) FOR DTCs

- Connect the scan tool.

- Enter the following diagnostic mode on the scan tool: Self Test- DSM (Driver Seat Module).

Are any DSM (Driver Seat Module) DTCs retrieved during self-test?

Yes
REFER to the Driver Seat Module (DSM) DTC Chart. Seats

No
GO to L3.

L3 CHECK THE TRANSMISSION RANGE (TR) PID

- Enter the following diagnostic mode on the scan tool: DataLogger/PCM PID: Transmission Range (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 L4.

No
To diagnose a transmission gear selector status concern, REFER to Automatic Transmission/Transaxle &/or Transmission Control Systems.

L4 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 (Driver Seat Module). REFER to Driver Seat Module (DSM) . CLEAR the DTCs. REPEAT the self-test.

No
To diagnose the key-in-ignition warning switch fault, REFER to Instrument Panel, Gauges and Warning Indicators.
