Pinpoint Test N: 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- MS-CAN (Medium Speed Controller Area Network) communication bus messages:
- key-in-ignition warning switch status

- gear selector position


- Wiring, terminals or connectors

- Key-in-ignition warning switch

- DSM (Driver Seat Module)

PINPOINT TEST N : 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 and power steering column (if equipped) soft stops must be reset. If a new seat track, recline motor or power steering column 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 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: 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.

N1 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 rearward.

- Place the memory seat, memory mirrors, adjustable memory pedals (if equipped) and adjustable memory steering column (if equipped) 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 easy entry/exit is ON and the seat does not move horizontally from the seat control switch, GO to Pinpoint Test L. Pinpoint Test L: The Memory Seat is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically/Recline

Otherwise, GO to N2.

N2 CHECK THE TRANSMISSION GEAR SELECTOR TRANSMISSION RANGE (TR) PID STATES

- Enter the following diagnostic mode on the scan tool: DataLogger- TCM (Transmission Control Module)- PID: TR.

- Operate the transmission gear selector in all positions while monitoring the TCM (Transmission Control Module) PID TR states.

Do the PID states agree with the selected positions?

Yes
GO to N3.

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

N3 CHECK THE IGNITION SWITCH POSITION (IGN_SW) PID

- Enter the following diagnostic mode on the scan tool: DataLogger- SJB (Smart Junction Box)- PIDs.

- Monitor the SJB (Smart Junction Box) PID IGN_SW with the key in and out of the ignition switch.

Does the PID agree with the key 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.
