Turn Signal Relay: Testing and Inspection

TURN SIGNAL & HAZARD RELAY INPUT TEST







CAUTION:
All SRS wire harnesses are covered with yellow insulation. Before you disconnect any part of an SRS wire harness, disconnect the airbag connectors.

Whenever the ignition switch is ON, or has been turned OFF for less than three minutes, be careful not to bump the SRS unit; the airbags could accidentally deploy and cause damage or injuries.

For additional precautions, refer to SRS Service Precautions.







1. Remove the turn signal/hazard relay from the under-dash fuse/relay box.
2. Inspect the relay 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 in-put tests at the socket.
- If a test indicates a problem, find and correct the cause, then recheck the system.
- If all the input tests prove OK, the turn signal/hazard relay must be faulty; replace it.
