Pinpoint Test G: Easy Exit/Easy Entry is Inoperative/Does Not Operate Correctly

Normal Operation

The Driver Seat Module (DSM) receives a key out command from the Body Control Module (BCM) over the Medium Speed Controller Area Network (MS-CAN) and moves 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 Medium Speed Controller Area Network (MS-CAN) status information:
- ignition status

- gear selector position


- Wiring, terminals or connectors

- Key-in-ignition warning switch

- DSM (Driver Seat Module)

PINPOINT TEST G : 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:
The transmission gear selector must be in PARK 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.

G1 CHECK FOR SEAT OPERATION AND RETRIEVE DTCs

- Ignition ON.

- Check the message center to verify the easy entry/exit feature is enabled. Refer to the Owner's Literature.

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

- Place the memory seat and memory mirrors in central travel positions.

- 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 OFF, turn the easy entry/exit feature ON 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.

If the seat does not move horizontally from the seat control switch, GO to Pinpoint Test E. Pinpoint Test E: The Power Seat Does Not Move Horizontally/Vertically/Recline - Driver, With Memory

Otherwise, GO to G2.

G2 CHECK THE TRANSMISSION GEAR SELECTOR TRANSMISSION RANGE (TR) PID STATES

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

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

Do the PID states agree with the selected positions?

Yes
GO to G3.
No
To diagnose a transmission gear selector (PRNDL) status concern, REFER to Automatic Transmission/Transaxle.

G3 CHECK THE KEY IN IGNITION SWITCH (KEY_IN_SW) PID

- Enter the following diagnostic mode on the scan tool: DataLogger- BCM (Body Control Module).

- Insert and remove the ignition key from the ignition lock cylinder while monitoring the KEY_IN_SW PID states.

Does the PID agree with key positions in and out of the ignition switch?

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.
