- Using a jumper wire, connect the dashboard wire harness B 6P connector (A) No. 6 terminal to body ground. The horns should sound.
- If the horns sound, go to step 4.
- If the horns don't sound, check the horn relay circuit.
- Check for continuity between the No. 6 terminal of the cable reel side 6P connector and body ground with the horn switch pressed.
- If there is continuity, the switch is OK.
- If there is no continuity, go to step 6.
- Remove the driver's airbag assembly (see AIR BAG RESTRAINT SYSTEMS
).
- Check for continuity between the cable reel No. 6 terminal (A) and the horn switch positive terminal (B).
- If there is no continuity, check for continuity of the radio remote switch harness. If the harness is OK, replace the cable reel (see AIR BAG RESTRAINT SYSTEMS
) and check for proper operation.
- If there is continuity, go to step 7.
