Pinpoint Test B: The Adjustable Steering Column Is Inoperative In One Or More Directions Using The Memory Position Switch, The RKE (Remote Keyless Entry) Transmitter Or The Easy Entry/Easy Exit Feature
- Refer to ADJUSTABLE STEERING COLUMN
for schematic and connector information.
Normal Operation and Fault Conditions
For RKE memory recall operation, the RTM sends RKE commands to the BCM over the MS-CAN. The BCM sends those commands to the GWM over the HS-CAN1 and the GWM sends those commands to the DSM over the MS-CAN. The DSM then commands the adjustable steering column tilt and telescopic motors to the desired positions.
For easy entry/exit feature operation, the GWM gathers various module messages (transmission gear position, ignition status and driver door ajar status) and relays these messages to the DSM. The DSM then commands the adjustable steering column tilt and telescopic motors to the desired positions.
For memory position recall operation using the memory position switch, the switch sends ground signals directly to the DSM, which then commands the adjustable steering column tilt and telescopic motors to the desired positions.

- DSM
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector. - B1 CHECK THE OPERATION OF THE ADJUSTABLE COLUMN USING THE STEERING COLUMN CONTROL SWITCH
- Operate the adjustable column in all directions using the steering column control switch.
Does the steering column move for more than one second in each direction using the steering column control switch?
Yes If the adjustable steering column is inoperative using the easy entry/exit feature, GO to B2 If the adjustable steering column is inoperative using the memory position switch, GO to B3 If the adjustable steering column is inoperative using an RKE transmitter, GO to B4 No If the steering column does not move at all in one or more directions using the steering column switch, GO to Pinpoint Test A If the steering column only moves in one second intervals (jog mode) in one or more directions using the steering column switch, GO to Pinpoint Test C - B2 VERIFY THE EASY ENTRY/EXIT FEATURE IS ENABLED
- Using the message center, enable the easy entry/exit feature. Refer to the Owner's Literature for additional instructions for using the message center.
- Activate the easy entry/easy exit feature by turning the ignition on and then off.
Does the adjustable steering column operate using the easy entry/easy exit feature?
Yes The repair is complete. INFORM the customer that the easy entry/easy exit feature was disabled and RETURN the vehicle to the customer. No GO to B5 - B3 CHECK THE OPERATION OF THE MEMORY SEATS AND MEMORY MIRRORS USING THE MEMORY POSITION SWITCH
- Check the operation of the seats and memory mirrors using the memory position switch. If necessary, refer to the Owner's Literature for additional instructions for programming a memory position.
Do the seats and mirrors operate correctly using the memory position switch?
Yes GO to B5 No DIAGNOSE the memory seat function. REFER to: Front Seats - B4 CHECK THE OPERATION OF THE MEMORY SEATS AND MEMORY MIRRORS USING THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER
- Check the operation of the seats and mirrors using a RKE transmitter. If necessary, refer to the Owner's Literature for additional instructions for programming a memory position to a RKE transmitter.
Do the seats and mirrors operate correctly using the RKE transmitter?
Yes GO to B5 No DIAGNOSE the RKE seat position recall function. REFER to: Front Seats - B5 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE BCM (BODY CONTROL MODULE), GWM (GATEWAY MODULE A) AND DSM (DRIVER FRONT SEAT MODULE)
- Ignition ON.
- Using a diagnostic scan tool, CARRY OUT a self-test for the following modules:
- BCM
- GWM
- DSM
- Record all Diagnostic Trouble Codes (DTCs) retrieved from the modules.
Are there any Diagnostic Trouble Codes (DTCs) present in any of the 3 modules?
Yes DIAGNOSE the BCM, GWM or DSM Diagnostic Trouble Codes (DTCs). Refer to the appropriate Electronic Feature Group article for the procedure. REFER to: Communications Network . REFER to: Front Seats No GO to B6 - B6 CHECK FOR CORRECT DSM (DRIVER FRONT SEAT MODULE) OPERATION
- Disconnect and inspect all DSM electrical connectors.
- Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary
- Connect the DSM electrical connectors.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new DSM. REFER to: Driver Front Seat Module (DSM) No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
