Inspection
Brake system warning lamp
1. Disconnect the connector from the brake fluid level sensor.
2. Connect a jumper wire between “G/Y” and “6” terminal
(body ground).
3. Start the engine and check that the BRAKE warning lamp
illuminates.
Caution
l Be sure that the parking brake is fully released be-
fore checking.
4. If there is no illumination, check the fuse, bulb, and wiring
harness.
Brake fluid level sensor
Connect an ohmmeter to each terminal of the brake fluid lev-
el sensor connector.
Check for continuity when the float is moved up and down.
The sensor is good if there is continuity when the float is be-
low the “MIN” mark, and if there is no continuity when the
float is above the “MAX” mark. If the sensor does not pass
this test, replace it.
Fuel-level warning lamp
1. Disconnect the connector from the fuel tank unit.
2. Connect the connector terminal “W/R” to the body ground.
3. Start the engine and check that the FUEL warning lamp il-
luminates.
4. If there is no illumination, check the fuse, warning lamp, and
wiring harness.
Alternator warning lamp
1. Start the engine, connect the connector terminal “W/B” to
a body ground.
2. Check that the alternator warning lamp illuminates.
3. If there is no illumination, check the warning lamps, wiring
harness and alternator. Replace or repair as necessary.
Engine oil pressure warning lamp
1. Disconnect the connector from the oil pressure switch.
2. Start the engine and connect the connector terminal “Y/R”
to a body ground.
3. Check that the “OIL” warning lamp illuminates. If it does
not, replace the sender switch or repair the wiring harness
if bulb is not burnt out.
