Pinpoint Tests

The Adjustable Steering Column is Inoperative in One or More Directions Using the Steering Column Control Switch


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

The SCCM receives input directly from the steering column control switch then sends a message along the High Speed Controller Area Network 2 (HS2-CAN) to the GWM indicating the desired steering column movement. The GWM sends the message to the DSM along the MS-CAN which activates the tilt and telescope (reach) motors depending on the message received.

A failure of the steering column control switch, circuits, motor or module cause the power adjustable column to become inoperative and a DTC may be set in the SCCM and the DSM .

The Adjustable Steering Column Is Inoperative In One Or More Directions Using The Memory Position Switch, The RKE Transmitter Or The Easy Entry Easy Exit Feature


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

For RKE memory recall operation, the RTM sends RKE commands to the BCM over a LIN . The BCM sends those commands to the GWM over the High Speed Controller Area Network 1 (HS1-CAN) and the GWM sends those commands to the DSM over the MS-CAN . The DSM then commands the adjustable steering column tilt and telescope motors to the desired positions.

For easy entry/exit feature operation the GWM gathers the 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 telescope 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 telescope motors to the desired positions.

A failure of the tilt or telescope motor sensor circuits, a failure of the RKE system, a failure of the memory recall feature or the easy entry/exit feature not enabled all cause the adjustable steering column to cease operation or to operate incorrectly.

The Adjustable Steering Column Operates In One Second Intervals When Using The Steering Column Control Switch (Jog Mode)


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

If an adjustable steering column tilt or telescope motor sensor (also known as the reach motor) DTC sets (or if either of the sensor circuits become open), the DSM does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operations. The affected steering column motor operates in jog mode. Jog mode allows limited operation of the affected steering column motor using only the steering column control switch. When the steering column control switch is operated in jog mode, the steering column moves in the desired direction for one second, then stops regardless of the length of time the switch is actually activated. The steering column control switch must be released, then activated again in order to move the steering column for an additional second.

B2340, B2341


Refer to Wiring Diagrams Cell 128 for schematic and connector information.

Normal Operation and Fault Conditions

To protect the power tilt and telescope motors, motor circuits and the electronics internal to the DSM , the DSM continually monitors both motors for a stall condition whenever the motors are activated. If the one or both motors stop moving unexpectedly for at least one-quarter of a second, the DSM stops applying power to the motors until the it receives a command to move the motor again. If this condition is detected during a DSM on-demand self test of the DSM , a power tilt or power telescope motor stall DTC is set.



  DTC Fault Trigger Conditions


DTC Description Fault Trigger Conditions
B2340 Column Reach Motor Stalled This DTC sets on-demand if the telescope motor does not move when commanded. Output to the motor is disabled if the stall lasts longer than one-quarter of a second.
B2341 Column Tilt Motor Stalled This DTC sets on-demand if the tilt motor does not move when commanded. Output to the motor is disabled if the stall lasts longer than one-quarter of a second.
