Diagnosis Procedure
INFOID:0000000006158389
Regarding Wiring Diagram information, refer to
.
1.
CHECK FUSES AND FUSIBLE LINK
Check that the following IPDM E/R fuses or fusible link are not blown.
Is the fuse blown?
YES
>> Replace the blown fuse or fusible link after repairing the affected circuit.
NO
>> GO TO 2
2.
CHECK BATTERY POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R.
3. Check voltage between IPDM E/R harness connectors and
ground.
Is the measurement value normal?
YES
>> GO TO 3
NO
>> Repair or replace harness.
3.
CHECK GROUND CIRCUIT
1. Turn ignition switch OFF.
2. Check continuity between IPDM E/R harness connectors and
ground.
Does continuity exist?
YES
>> Inspection End.
NO
>> Repair or replace harness.
Terminal No.
