Steering Column

Pinpoint Test B: The Adjustable Steering Column is Inoperative in One or More Directions - Using the Memory SET Switch Buttons/Using an RKE (Remote Keyless Entry) Transmitter/Using the Easy Entry/Exit Feature

Normal Operation

When the desired memory position is selected using the memory SET switch or an Remote Keyless Entry (RKE) transmitter, the Driver Seat Module (DSM) communicates the desired steering column position in a message on the Medium Speed Controller Area Network (MS-CAN) to the Body Control Module (BCM). The BCM (Body Control Module) acts as a gateway module, relaying the message to the Steering Column Control Module (SCCM) over the High Speed Controller Area Network (HS-CAN). The SCCM (Steering Column Control Module) monitors the position of the adjustable steering column using Hall-effect type rotation sensors that are integral to the tilt and telescoping motors. The sensors provide a digital signal used by the SCCM (Steering Column Control Module) to calculate the position of the steering column in relation to the full forward/rearward and full up/down positions. The SCCM (Steering Column Control Module) uses these signals to store and recall memory positions, carry out easy entry/exit operations and to make sure the tilt and telescope motors do not stall against the steering column end of travel Steering Column. If a tilt or telescope motor sensor DTC sets, the SCCM (Steering Column Control Module) does not recall a programmed memory position or automatically position the steering column during the easy entry/exit operation. If a DTC sets for either sensor, the affected adjustable 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. The steering column control switch must be released, then pressed again in order to move the steering column for an additional second.

This pinpoint test is intended to diagnose the following:

- Entry/exit feature is disabled in the message center

- Wiring, terminals or connectors

- Memory SET switch

- RKE (Remote Keyless Entry) transmitter

- DSM (Driver Seat Module)

- BCM (Body Control Module)

- SCCM (Steering Column Control Module)

PINPOINT TEST B : THE ADJUSTABLE STEERING COLUMN IS INOPERATIVE IN ONE OR MORE DIRECTIONS - USING THE MEMORY SET SWITCH BUTTONS/USING AN RKE (Remote Keyless Entry) TRANSMITTER/USING THE EASY ENTRY/EXIT FEATURE

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

B1 CHECK THE OPERATION OF THE ADJUSTABLE COLUMN USING THE STEERING COLUMN CONTROL SWITCH

- Operate the adjustable steering 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 SET switch, GO to B3.

If the adjustable steering column is inoperative using an RKE (Remote Keyless Entry) transmitter, GO to B4.
No
If the steering column does not move in any direction at all using the steering column switch, GO to Pinpoint Test A. Pinpoint Test A: The Steering Column is Inoperative In One Or More Directions - Using The Steering Column Control Swith

If the steering column moves in only one second intervals (jog mode) in one or more directions using the steering column switch, GO to Pinpoint Test C. Pinpoint Test C: The Adjustable Steering Column Operates In One Second Intervals When Using The Steering Column Control Switch

B2 VERIFY THE EASY ENTRY/EXIT FEATURE IS ENABLED

- Verify the easy entry/exit feature is enabled using the message center. Refer to the Owner's Literature for additional instructions for using the message center.

Does the message center indicate that the easy entry/exit feature is enabled?

Yes
GO to B5.
No
TOGGLE the easy entry/exit feature on using the message center controls. TEST the system for normal operation.

B3 CHECK THE OPERATION OF THE MEMORY SEATS, MEMORY MIRRORS AND STEERING COLUMN USING THE MEMORY SET SWITCH

- Check the operation of the seats, memory mirrors and steering column using the memory SET switch. Refer to the Owner's Literature for additional instructions for programming a memory position.

Do the seats and mirrors operate properly using the memory SET switch?

Yes
If only the adjustable steering column is inoperative using the memory SET switch, GO to B5.
No
If the seats and mirrors are also inoperative using the memory SET switch, REFER to Seats.

B4 CHECK THE OPERATION OF THE MEMORY SEATS, MIRRORS AND STEERING COLUMN USING AN RKE (Remote Keyless Entry) TRANSMITTER

- Check the operation of the seats, mirrors and steering column using an RKE (Remote Keyless Entry) transmitter. Refer to the Owner's Literature for additional instructions for programming a memory position to an RKE (Remote Keyless Entry) transmitter.

Do the seats and mirrors operate correctly using an RKE (Remote Keyless Entry) transmitter?

Yes
If only the adjustable steering column is inoperative using an RKE (Remote Keyless Entry) transmitter, GO to B5.
No
If the seats and mirrors are also inoperative using an RKE (Remote Keyless Entry) transmitter, REFER to Seats.

B5 CHECK FOR DSM (Driver Seat Module), BCM (Body Control Module) AND SCCM (Steering Column Control Module) DTCs

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: Self Test- DSM (Driver Seat Module).

- Enter the following diagnostic mode on the scan tool: Self Test- BCM (Body Control Module).

- Enter the following diagnostic mode on the scan tool: Self-Test- SCCM (Steering Column Control Module).

- Record all DTCs retrieved from the DSM (Driver Seat Module), BCM (Body Control Module) and SCCM (Steering Column Control Module).

Are any symptom or communication related DTCs present?

Yes
To diagnose the DSM (Driver Seat Module) DTCs, REFER to Seats.

To diagnose the BCM (Body Control Module) DTCs, REFER to Body Control Systems.

To diagnose the SCCM (Steering Column Control Module) DTCs, REFER to Steering Column.
No
INSTALL a new SCCM (Steering Column Control Module). TEST the system for normal operation.
