Initial Inspection and Diagnostic Overview

- Circuit Z11, which supplies a ground for the PCM sensors, has the same termination point as the Z12 circuit. This ground terminates at the right headlamp ground located at the right front frame rail.
- If the system loses ground for the ganged circuits the vehicle will not operate. Check the connection at the ground eyelet.
