Check for electrical continuity between the Black terminal and ground on the main wiring harness.
If there is no electrical connection, then the break in the Black wire between the control module and points G8, G10 should be repaired.
If there is an electrical connection, then the ignition should be turned on.
Caution: The coolant temperature must be below 60°C.
Next, measure the voltage between the Black/Yellow (+) and Black (-) terminals on the main wiring harness.
If there is no voltage, then check fuse #12 (15 A). If the fuse is OK, then repair the break in the Black/Yellow wire between the control module and fuse #12.
If there is battery voltage, then measure the voltage between the White/Blue (+) and Black (-) terminals on the main wiring harness.
If there is no voltage, then you should check for a break in the White/Blue wire between the control module and the generator.
If there is battery voltage, then measure the voltage between the Yellow/Green (+) and Black (-) terminals on the main wiring harness.
If there is no voltage, then you should check for a break in the Yellow/Green wire between the control unit and the EFE control module.
If battery voltage is present, the EFE control module should be replaced and retested.
