[QUOTE="Vinnie_B, post: 16941521, member: 201678"] The DTC sets when the PCM commands the supercharger CAC pump to operate but no current is detected. Check the following: [LIST] [*]CAC pump motor circuit open [*]CAC pump relay coil open [*]CAC pump circuit open between the relay and the CAC pump [*]CAC pump motor short [*]PCM circuit open between the relay and the PCM [*]Incorrect CAC pump ground connection [/LIST] **Check for voltage at the relay connector and check the ground connection of the CAC pump motor.
