Inspect the connector and socket terminals to be sure they are all making good contacl.
. lf the terminals are bent, loose or corroded, repair them as necessary, and recheck the system
. lf the terminals look OK, make rhe following input tests at the connector.
- lf anv test indicates a problem, find and correct the cause, then recheck ihe system
- lf all the input tests prove OK, the control unit must be faulty; replace it
