    1. Check fuse #22 10A in the engine compartment fuse box for battery voltage at all times. Replace the fuse as needed and recheck operation.

    2. If the fuse is OK, access the Powertrain Control Module (PCM) connector. Check the Pink/Light Blue (PK/LB) wire at pin 55 for battery voltage at all times from fuse #22. If there is low or no voltage on the wire, locate and repair the open circuit between the engine compartment fuse box and PCM.
