Check Oil Level Indicator Does Not Light With Oil Level Low

Turn ignition off. Disconnect oil level module connector. Connect fused jumper wire between oil level module connector terminal No. 6 (Brown/White wire) and ground. Turn ignition on. If CHECK OIL LEVEL indicator comes on, go to next step. If CHECK OIL LEVEL indicator does not come on, check Brown/White wire for an open circuit or high resistance. If wiring is okay, disconnect instrument cluster connector C2. Ensure good terminal contact is present at connector terminal A8. If all connectors and circuits are okay, replace instrument cluster.
Perform diode check between oil level module connector terminals No. 1 (Orange/Black wire) and No. 2 (Red/White wire). If tester indicates about 1-2 volts with meter probes in one direction only, go to next step. If tester does not indicate as specified, check Orange/Black wire for an open circuit or high resistance. If wiring is okay, check all connectors for good terminal contact. If connections are okay, replace low oil level sensor.
Measure voltage between oil level module connector terminal No. 9 (Brown wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Brown wire for an open circuit, high resistance, or short circuit to ground.
Measure voltage between oil level module connector terminal No. 10 (Orange wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Orange wire for an open circuit, high resistance, or short circuit to ground.
Measure voltage between oil level module connector terminals No. 10 (Orange wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Orange wire for an open circuit, high resistance, or short to ground.
Measure voltage between oil level module connector terminals No. 10 (Orange wire) and No. 5 (Black/White wire). If battery voltage is present, check oil level module connector for good contact at terminals No. 5, 6, 9, and 10. If terminal contact is okay, replace oil level module. If battery voltage is not present, check Black/White or Black wire for an open circuit or high resistance.

Turn ignition off. Disconnect oil level module connector. Connect a fused jumper wire between oil level module connector terminal NO. 6 (Brown/White wire) and ground. Turn ignition on. If CHECK OIL LEVEL indicator comes on, go to next step. If CHECK OIL LEVEL indicator does not come on, check Brown/White wire for an open circuit or high resistance. Also check instrument cluster connector C2 for good terminal contact. If terminal contact is okay, replace instrument cluster.
Measure voltage between oil level module connector terminals No. 1 (Orange/Black wire) and No. 2 (Red/White wire). If meter indicates about 1-2 volts in one direction and infinity with probes reversed, go to next step. If meter does not indicate about 1-2 volts in one direction and infinity with probes reversed, check Orange/Black and Red/White wires for an open circuit. Check in-line connectors and oil level sensor connector for good terminal contact. If all circuits are okay, replace low oil level sensor.
Measure voltage between oil level module connector terminal No. 9 (Brown wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Brown wire for an open circuit, high resistance, or short to ground.
Measure voltage between oil level module connector terminal No. 10 (Orange wire) and ground. If battery voltage is present, go to next step. If battery voltage is not present, check Orange wire for an open circuit, high resistance, or short to ground.
Measure voltage between oil level module connector terminal No. 10 (Orange wire) and terminal No. 5 (Black/White wire). If battery voltage is present, check oil level module connector for good terminal contact. If terminal contact is okay, replace OIL LEVEL MODULE. If battery voltage is not present, check Black/White or Black wire for an open circuit or high resistance.
