Troubleshooting Hints

1. If more than one warning light fails, check power and ground wires common to all affected warning lights.
2. If the brake, brake pad wear and transmission/transfer box oil temperature warning lights that are checked during crank do not light with the Ignition Switch in position III, check the B, BS and WR wires at the Brake Indicator Check Relay (K106). If all are OK, check the Brake Indicator Check Relay.
3. If none of the audible warning tones operate, check the PW and B wires at the Audible Warning Unit (Z109). If all are OK, check the Audible Warning Unit.
4. If the seat belt tone is not heard, check the WB wire, B wire and Driver Seat Buckle Switch (X120). If all are OK, check the Audible Warning Unit (Z109).
5. If the driver's door open/key-in-ignition tone is not heard, check the Driver Door Switch (X118) by opening the driver's door and seeing that the interior lights come on. If OK, check the PW wire, WP wire and the Ignition Key Switch (X177). If all are OK, check the Audible Warning Unit (Z109).
6. If the transfer box neutral tone is heard at all times, check the BK wire, B wire and Transfer Box Position Switch (X175). If all are OK, check the Audible Warning Unit (Z109).
