Code A012: Right Front Release Solenoid Open Or Shorted To Ground
When front enable relay is energized, voltage is applied to right front solenoid. To activate right front release solenoid, the anti-lock brake controller grounds terminal "C" of right front solenoid. To set Code A012, the following conditions must occur.
- Front enable relay is energized.
- Right front release solenoid control is open.
- Anti-lock brake controller senses no voltage at terminal 1C9.
- If Code A009 is set, power feed to right front solenoid is open.
- Tech I (94-00101-A) scanner will display HI feedback if voltage is available at terminal 1C9.
- A short to ground exists if test light is on.
- If a short to ground does not exist with anti-lock brake controller disconnected, replace unit.
- If test light is on, Brown wire between right front solenoid and front enable relay is okay.
- If continuity to ground through front enable relay contacts is present, open is in anti-lock brake controller.
