Pinpoint Test Q: 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) and powers the driver seat rearward about 50.8 mm (2 in) maximum.

This pinpoint test is intended to diagnose the following:

- Easy entry/exit feature is not enabled

- Wiring, terminals or connectors

- Missing status information (Controller Area Network (CAN) communication bus messages):

- Key-in-ignition warning switch (if equipped)

- Start/stop switch (if equipped)

- DSM (Driver Seat Module)

PINPOINT TEST Q : EASY EXIT/EASY ENTRY IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

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: If a new DSM (Driver Seat Module) has been installed, all seat soft stops must be reset. If a new seat track or recline motor has been installed, only reset the soft stops for that component being installed new. To reset the soft stops, refer to Principles of Operation. Principles of Operation

NOTE: The transmission gear selector must be in PARK and either the key removed (without Intelligent Access) or the ignition OFF (with Intelligent Access) for the easy entry/exit feature to function.

NOTE: Make sure all memory seat DTC and symptom based faults are corrected before proceeding with easy entry/exit diagnosis. Verify the PID(s) states agree with the ignition and transmission gear selector in all positions before proceeding with easy entry/exit diagnosis.

NOTE: Refer to Description and Operation, Intelligent Access with Push Button Start in Antitheft and Alarm Systems to review the procedures for achieving the various ignition states (ignition OFF, ignition in ACCESSORY, ignition ON, ignition START) on vehicles with this feature.

Q1 CHECK THE DRIVER POWER SEAT OPERATION

- Ignition ON.

- Check the message center to verify the easy entry/exit feature is turned on.
- The easy entry/exit feature can be enabled/disabled using a scan tool in module programming. When enabled, the feature becomes a user accessible item on the message center allowing the user to turn the feature on and off. Refer to the Owner's Literature or Instrument Panel, Gauges and Warning Indicators for information on the message center.


- Using the seat control switch, verify the driver power seat operates fully forward and backward.

- 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?

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

No
If disabled, ENABLE the easy entry/exit feature with the message center. REFER to the Owner's Literature or Instrument Panel, Gauges and Warning Indicators. TEST the system for normal operation. If OK, INSTRUCT the customer on correct system operation.

Otherwise, GO to Q2.

Q2 CHECK THE PCM TRANSMISSION RANGE (TR) PID STATES

- Enter the following diagnostic mode on the scan tool: DataLogger- PCM PID: TR.

- Operate the transmission gear selector in all positions while monitoring the PCM PID TR states.

Do the PID states agree with the selected positions?

Yes
GO to Q3.

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

Q3 CHECK THE DDM (Driver Door Module) IGNITION KEY STATUS (KEYST) PID STATES

- Enter the following diagnostic mode on the scan tool: DataLogger- DDM (Driver Door Module)- PIDs.

- Operate the ignition while monitoring the DDM (Driver Door Module) KEYST PID states.
- For vehicles equipped with an ignition lock cylinder and key, insert and remove the ignition key from the ignition lock cylinder.

- For vehicles equipped with passive entry/passive start, push the ignition button ON and OFF.


Do the PID states agree?

Yes
INSTALL a new DSM (Driver Seat Module). REFER to Driver Seat Module (DSM) . CLEAR the DTCs. REPEAT the self-test.

No
For vehicles with passive entry/passive start, to diagnose an ignition status concern, REFER to Steering Column.

For vehicles using an ignition key, to diagnose an ignition status concern, REFER to Instrument Panel, Gauges and Warning Indicators.
