Pinpoint Test K: Easy Exit/Easy Entry is Inoperative/Does Not Operate Correctly
Normal Operation
The Driver Seat Module (DSM) receives a transmission park and key in/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:
- Wiring, terminals or connectors
- Easy exit/easy entry not enabled
- Missing status information (Controller Area Network (CAN) communication bus message):
- ignition switch status
- gear selector position
- Key-in-ignition warning switch
- Instrument Cluster (IC) module
- DSM
PINPOINT TEST K: 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 and the driver seat must be at least 51 mm (2 in) from its rear stopping point 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.
-------------------------------------------------
K1 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 adjustable memory pedals 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. Diagnostic Trouble Code Tests and Associated Procedures
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 I. Pinpoint Test I: The Memory Seat Is Inoperative/Does Not Operate Correctly - Does Not Operate Horizontally/Vertically/Recline
Otherwise, GO to K2.
-------------------------------------------------
K2 CHECK DSM TRANSMISSION GEAR SELECTED (TRANSGEAR) PID STATES
- Enter the following diagnostic mode on the scan tool: DataLogger - DSM - PID: TRANSGEAR (PRNDL).
- Operate the transmission gear selector in all positions while monitoring the following DSM PID TRANSGEAR states:
- Drive1
- Drive2
- Drive3
- D6_PRK
- NTRL
- REV
- D6_PRK
- Do the PID states agree with the selected positions?
Yes
GO to K3.
No
To diagnose a transmission gear selector (PRNDL) status concern, REFER to Automatic Transmission/Transaxle &/or Transmission Control Systems.
-------------------------------------------------
K3 CHECK THE IGNITION KEY IN/OUT (IGN_KEY) PID
- Enter the following diagnostic mode on the scan tool: DataLogger - IC Module - PID: IGN_KEY PID.
- Insert and remove the ignition key into the ignition lock cylinder while monitoring the following IC module PID IGN_SW states:
- In
- Out
- Monitor the IC module PID IGN_SW with the key in and out of the ignition switch.
- Do the IC module PID states agree?
Yes
INSTALL a new DSM and CARRY OUT Programmable Module Installation (PMI). REFER to Body Control Systems. REPEAT the self-test. CLEAR the DTCs. Programmable Module Installation (PMI)
No
To diagnose the key-in-ignition warning switch fault, REFER to Instrument Panel, Gauges and Warning Indicators.
