B2225-00-(SCM) STEERING COLUMN MODULE INTERNAL





For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The Steering Control Module (SCM) for this vehicle is integral to the Steering Column Control Module (SCCM). The SCCM is located near the top of the steering column below the steering wheel. The SCCM includes the steering column shroud, the Steering Angle Sensor (SAS), the Clockspring, the Multifunction Switch, a Steering Column Power Tilt and Telescope Switch (if equipped), and a trim cover. The SCCM is replaced as an entire assembly.

- When Monitored:
With the ignition on.

- Set Condition:
The Steering Column Control Module (SCCM) has set an internal electronic failure status.





1. CHECK FOR AN ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
1. Turn the ignition on.
2. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. LOW BATTERY VOLTAGE




1. Turn the ignition off.
2. Disconnect the Steering Control Module C1 harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (A929) Fused B(+) circuit.

Is battery voltage present?

Yes

- Replace the Steering Column Control Module (SCCM). Steering Column Module - Removal.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Repair the (A929) Fused B(+) circuit for an open, short to ground or high resistance.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
