Central Processing Unit (CPU)

CPU acts as an electrical load sensor. Remove CPU from behind left front side trim panel near door. See Fig 1 -10. Check voltage at terminals of CPU connector. See appropriate CPU UNIT VOLTAGE CHART. If voltages are incorrect, check appropriate circuit. If circuits are okay but voltages are still incorrect, replace CPU.
