Turn Signal/Hazard Relay Input Test

1. Remove the dashboard lower cover. Remove the

turn signal/hazard relay from the left kick panel,

then disconnect the 6-P connector.

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 cor-

rect the cause, then recheck the system.

— If all the input tests prove OK, the control unit

must be faulty; replace it.
