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 MS-CAN and powers the driver seat rearward about 50.8 mm (2 in).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Key-in-ignition warning switch
- Instrument Cluster (IC) module
- DSM



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

-------------------------------------------------
L1 CHECK POWER SEAT OPERATION


- Ignition ON.
- Check the message center to verify the easy entry/exit feature is enabled.
- 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.
- Operate the seat fully forward and rearward with the switch to verify the power seat track is OK.
- Does the power seat operate forward and rearward correctly?

Yes
GO to L2.

No
REFER to the Symptom Chart for diagnosis of inoperative driver power seat horizontal movement.

-------------------------------------------------
L2 CHECK EASY EXIT OPERATION


- Position the driver seat at least 50.8 mm (2 in) from the rear stop point.
- Ignition OFF.
- Remove the key from the ignition.
- Does the seat move rearward approximately 50.8 mm (2 in)?

Yes
GO to L5.

No
GO to L3.

-------------------------------------------------
L3 CHECK THE DSM IGNITION KEY (IGN_KEY) PID STATES


- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: DataLogger - DSM - PID: IGN_KEY.
- Monitor the IGN_KEY PID states with the ignition key in and with the key removed.
- Do the PID states agree with the switch positions?

Yes
GO to L4.

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

L5 CHECK THE EASY ENTRY OPERATION


- Insert the ignition key.
- Does the driver power seat move forward approximately 50.8 mm (2 in)?

Yes
The system is operating correctly at this time. RETEST the system for intermittent operation. If no fault is found, INSTRUCT the customer on the correct operation of the system.
