Action Taken When the DTC Sets

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The Service 4-Wheel Steer indicator in IPC will be displayed.
The code is displayed on the scan tool as DTC C0455.
The output to the motor is ramped down slowly, at a rate of 2 degrees per second to 0 degrees and held.
The rear wheels will be returned to the centered position.
The internal power relay of the rear wheel steering control module is turned off, which in turn shuts down the 12-volt reference to the SWPS. This results in all digital signals being displayed as low by the scan tool. Battery voltage and hall sensor reference voltage will also display low voltage. This occurs only when the DTC is current.
