Upon further investigation the technician may find the following DTCs set in the PCM memory:P0556 - Brake Booster Pressure Sensor Circuit Performance. U0428 - Implausible Data Received From Steering Angle Sensor Module. U1504 - Implausible Message Data Length Received From Steering Angle Sensor. C0501 - Left Front Wheel Speed Sensor Range/Performance. C0507 - Right Front Wheel Speed Sensor Range/Performance. C050D - Left Rear Wheel Speed Sensor Range/Performance. C0513 - Right Rear Wheel Speed Sensor Range/Performance. Erroneously set Wheel Speed Sensor DTCs listed above will not turn on the MIL by design but may be found during a vehiclediagnostic scan.Some customers may also experience the following condition:During an engine limp mode condition, the transmission remains in a fixedgear. In addition the following enhancements are included:Calibration update to allow the throttle body to be cycled while the engine isoff, for diagnostic purposes.
