WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Wiring Diagrams Adjustable Steering Column for schematic and connector information.
Normal Operation and Fault Conditions

REFER to: Steering Column - System Operation and Component Description .

Possible Sources
- Wiring, terminals or connectors
- Adjustable steering column tilt motor
- Adjustable steering column telescopic motor
- DSM
- SCCM
- GWM
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

A1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a diagnostic scan tool, carry out the Network Test.
Do the GWM, SCCM and DSM all pass the Network Test?

Yes GO to A2

No DIAGNOSE the no communication concern for the GWM, SCCM or DSM.

A2 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE GWM (GATEWAY MODULE A)
- Using a diagnostic scan tool, carry out the GWM self-test.
Are any Diagnostic Trouble Codes (DTCs) present in the GWM?

Yes DIAGNOSE the GWM Diagnostic Trouble Codes (DTCs).

No GO to A3

A3 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE SCCM (STEERING COLUMN CONTROL MODULE)
- Using a diagnostic scan tool, carry out the SCCM self-test.
Are any SCCM Diagnostic Trouble Codes (DTCs) present?

Yes DIAGNOSE the SCCM Diagnostic Trouble Codes (DTCs). REFER to: Steering Wheel and Column Electrical Components .

No GO to A4

A4 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE DSM (DRIVER FRONT SEAT MODULE)

Using a diagnostic scan tool, carry out the DSM self-test.

Are any Diagnostic Trouble Codes (DTCs) present in the DSM?

Yes	For DSMDTC B1375:11, B1375:12, B1375:13, B137E:11, B137E:12 or, B137E:13, GO to Pinpoint Test D For all other DSM Diagnostic Trouble Codes (DTCs), REFER to: Front Seats .

GO to A5

A5 CHECK THE SCCM (STEERING COLUMN CONTROL MODULE) STEERING COLUMN ADJUST SWITCH (STRCOL_ADJ) PID (PARAMETER IDENTIFICATION)

Using a diagnostic scan tool, view the SCCM Parameter Identification (PIDs).

Access the SCCM and monitor the STRCOL_ADJPIDwhile activating the steering column control switch in all 4 directions.

Does the PID display match each steering column control switch position?

Yes

GO to A6

If the PID displays "No Movement" or "Invalid", or if the PID display does not match one or more switch positions, INSTALL a new steering column control switch. REFER to: Steering Column Control Switch . TEST the system for normal operation. If the adjustable steering column is still inoperative, INSTALL a new SCCM. REFER to: Steering Column Control Module (SCCM) . REFER to: Steering Column Control Module (SCCM) - Vehicles With: Adaptive Steering .

A6 CHECK THE ADJUSTABLE STEERING COLUMN MOTOR CIRCUITS FOR AN OPEN

Ignition OFF.

Disconnect DSM C341A

Disconnect DSM C341B

Disconnect Adjustable Steering Column Tilt Motor C2600.

Disconnect Adjustable Steering Column Telescope Motor C2601.

Are the resistances greater than 10, 000 ohms?

Yes

GO to A8

No	REPAIR the circuit. TEST the system for normal operation.

A8 CHECK THE ADJUSTABLE STEERING COLUMN TILT MOTOR OPERATION

Connect Adjustable Steering Column Tilt Motor C2600.

Connect a fused jumper wire:

Does the tilt motor move the steering column when the fused jumper wire is connected to ground?

Yes

GO to A9

No	INSTALL a new adjustable steering column tilt motor. REFER to: Steering Column Tilt Motor .

A9 CHECK THE ADJUSTABLE STEERING COLUMN TELESCOPIC MOTOR OPERATION

Connect Adjustable Steering Column Telescope Motor C2601.

Does the telescopic motor move the steering column when the fused jumper wire is connected to ground?

Yes

GO to A10

No	INSTALL a new telescopic motor. REFER to: Steering Column Telescopic Motor .

A10 CHECK FOR CORRECT DSM (DRIVER FRONT SEAT MODULE) OPERATION

Inspect DSM 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 DSM C341A and C341B.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable service articles: 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.
