Is the fuse fusing?
YES >> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is
blown.
NO >> GO TO 2.
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connectors.
3. Check voltage between BCM harness connector and ground.
Is the measurement value normal?
YES >> GO TO 3.
NO >> Repair harness or connector.
3.CHECK GROUND CIRCUIT
Check continuity between BCM harness connector and ground.
Does continuity exist?
YES >> INSPECTION END
NO >> Repair harness or connector.

INFOID:0000000003900506
1.CHECK FUSES AND FUSIBLE LINK
Check that the following IPDM E/R fuses or fusible links are not blown.
Is the fuse fusing?
YES >> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is
blown.
NO >> GO TO 2.
2.CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.

OIL PRESSURE SWITCH SIGNAL CIRCUIT
OIL PRESSURE SWITCH SIGNAL CIRCUIT
DescriptionINFOID:0000000003792577
Detects the engine oil pressure and transmits the oil pressure switch signal to IPDM E/R.
Component Function CheckINFOID:0000000003792578
1.CHECK COMBINATION METER INPUT SIGNAL
Select the “Data Monitor” for the “METER/M&A” and check the “OIL W/L” monitor value.
>> INSPECTION END
Diagnosis ProcedureINFOID:0000000003792579
1.CHECK OIL PRESSURE SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector and oil pressure switch connector.
3. Check continuity between IPDM E/R harness connector terminal and oil pressure switch harness connec-
tor terminal.
4. Check continuity between IPDM E/R harness connector terminal and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Repair harness or connector.
