Turn Signal/Hazard Relay Input Test

1. Remove the dashboard lower cover. Remove the turn signal/hazard relay from the left kick panel, then dis-
connect the 6-P connector.
2. Inspect the connector 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 in-
put tests at the connector. If any test indicates a problem, find and cor-
rect the cause, then recheck the system. If all the input tests prove OK, the control unit
must be faulty; replace it.
