Diagnostic Steps Performed/Parts Replaced

The customer had previously replaced the steering column & module, and then brought the vehicle here, to the shop. They believed only calibration was needed but after bringing it into the bay for a closer look, saw that the steering wheel was off-center by > 100°. This was the first fix performed, making sure the clock spring (aka “contact coil”) was also centered.

Next, the power and ground in the module were verified and then followed the OEM Testing steps under this DTC (C0545) – Steering Column “without HP5 (Steering Gear Replacement).” When testing for resistance, At EACH step, the values were within spec. Then I read, at the end of each test, “If all circuits test normal, replace the power steering control module (PSCM).” After replacing the PSCM, it must be configured with the proper tuning profile using the service programming system (SPS).

After the customer had replaced the steering column & module, the steering wheel was off-center and the PSCM needed calibration.

After centering the steering wheel, a sensor calibration was performed with the scanner, and the complaint was fixed. No additional programming for the PSCM was necessary.
