Control Unit Input Test
1. Disconnect the 7-P connector from the control unit.
2. Inspect the connector and socket terminals to be sure
they are all making good contact.
• If the terminals are bent, loose or corroded, repair
them as necessary, and recheck the system.
• If the terminals look OK, make the following input
tests at the connector.
— If any test indicates a problem, find and correct
the cause, then recheck the system.
— If all the input tests prove OK, the control unit
must be faulty; replace it.
