Pinpoint Test N: Easy Entry/Easy Exit is Inoperative/Does Not Operate Correctly
Normal Operation
The Driver Seat Module (DSM) receives a key out command from the Smart Junction Box (SJB) and a transmission range selection of park from the PCM, both coming over the Medium Speed Controller Area Network (MS-CAN) communication network and powers the memory driver seat rearward about 2 inches. When the ignition key is inserted, the memory driver seat goes back to its last known position.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Easy entry/easy exit not enabled
- Key-in-ignition warning switch
- DSM
- Missing Controller Area Network (CAN) status information (CAN communication message):
- ignition switch status
- gear selector position
PINPOINT TEST N: EASY ENTRY/EASY EXIT 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/easy exit feature to function.
NOTE: Make sure all memory seat DTC and symptom based faults are corrected before proceeding with easy entry/easy exit diagnosis. Verify the PID(s) states agree with the ignition switch and transmission gear selector in all positions before proceeding with easy entry/easy exit diagnosis.
-------------------------------------------------
N1 CHECK THE DRIVER POWER SEAT OPERATION
- Ignition ON.
- Check the message center to verify the easy entry/easy exit feature is enabled.
- The easy entry/easy 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.
- NOTE: During the self-test, each memory motor will be requested to move for one second. If a motor is near the end of travel, that position sensor feedback will not change as expected for one second resulting in a false DTC.
- Place the memory seat and memory mirrors in central travel positions.
- Connect the scan tool.
- Enter the following diagnostic mode on the scan tool: Self Test - DSM.
- Are any DSM DTCs retrieved?
Yes
REFER to the Driver Seat Module (DSM) DTC Chart. Driver Seat Module (DSM) DTC Chart
No
If disabled, ENABLE the easy entry/easy exit feature with the message center. REFER to the Owner's Literature - Driver Controls for easy entry/easy exit feature enable/disable instructions. TEST the system for normal operation. If OK, INSTRUCT the customer on correct system operation.
If easy entry/easy exit is enabled and the seat does not move horizontally from the seat control switch, GO to Pinpoint Test J for MKX vehicles or GO to Pinpoint Test L for Edge vehicles. Pinpoint Test J: The Memory Seat is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically/Recline Pinpoint Test L: The Memory Seat is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically
Otherwise, GO to N2.
-------------------------------------------------
N2 CHECK THE PCM TRANSMISSION RANGE (TR) PID STATES
- Connect the scan tool.
- Ignition ON.
- 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 N3.
No
To diagnose a transmission gear selector (PRNDL) status concern, REFER to Automatic Transmission/Transaxle &/or Transmission Control Systems.
-------------------------------------------------
N3 CHECK THE GEM/SJB FOR CORRECT IGNITION SWITCH POSITION (IGN_SW) STATES
- Enter the following diagnostic mode on the scan tool: DataLogger - GEM/SJB PID: IGN_SW.
- Insert and remove the ignition key into the ignition lock cylinder while monitoring the following DSM PID IGN_SW states:
- Key In
- Key Out
- Monitor the DSM ignition switch position PID with the ignition key in and with the key removed.
- Do the DSM PID states agree?
Yes
INSTALL a new DSM. REFER to Body Control Systems. REPEAT the self-test. CLEAR the DTCs.
No
To diagnose the key-in-ignition warning switch fault, REFER to Instrument Panel, Gauges and Warning Indicators.
