DTC C1B00:2F (Steering Angle Sensor: Signal Erratic) - If the signal is calculated to be outside the expected range, DTC C1B00:2F will be set. If the tie rods (inner or outer) have been incorrectly installed or if the vehicle has sustained damage to the EPAS gear and/or associated steering/suspension components, DTC C1B00:2F may set.
DTC C1B00:62 (Steering Angle Sensor: Signal Compare Failure) - If the calculated signal does not match other sensor input, DTC C1B00:62 will be set.
DTC C1B00:64 (Steering Angle Sensor: Signal Plausibility Failure) - The PSCM calculates an absolute steering position offset based on several inputs, when the steering wheel compensation message from the ABS module matches or exceeds this calculation, the PSCM sets this DTC. Torque steer compensation is suppressed for the remainder of the ignition cycle in which DTC C1B00:64 is set.
Possible Causes Inner tie rods
Steering gear internal failure.
PSCM internal failure
DTCs present in the ABS module.
ABS module HS-CAN bus concern.
Diagnostic Aids When DTC C1B00:2F is set, the PSCM will transmit an invalid steering angle message over the HS-CAN bus.
When DTC C1B00:62 is set, the PSCM will remove steering assist, and enter into a manual mode and transmit an invalid steering angle message over the HS-CAN bus. The PSCM will also send a message to the IPC to display the POWER STEERING ASSIST FAULT message in the message center.
DTC C1B00:64 indicates a possible measurement or calculation error between the PSCM and the ABS module. Torque steer compensation is suppressed for the remainder of the ignition cycle in which DTC C1B00:64 is set. This DTC is for information only. Do not install a new PSCM for PSCM DTC C1B00:64
