YES
>> GO TO 2.
NO
>> Repair the terminal and connector.
2.
CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect the connector of IPDM E/R.
2. Check the resistance between the IPDM E/R harness connector terminals.
Is the measurement value within the specification?
YES
>> GO TO 3.
NO
>> Repair the IPDM E/R branch line.
3.
CHECK POWER SUPPLY AND GROUND CIRCUIT
Check the power supply and the ground circuit of the IPDM E/R. Refer to
Is the inspection result normal?
YES (Present error)>>Replace the IPDM E/R. Refer to
PCS-30, "Removal and Installation"
YES (Past error)>>Error was detected in the IPDM E/R branch line.
NO
>> Repair the power supply and the ground circuit.
