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 PCS-16, "
Diagnosis Procedure".
Is the inspection result normal?
YES (Present error)>>Replace the IPDM E/R. Refer to PCS-30, "Removal and Installation of IPDM E/R".
YES (Past error)>>Error was detected in the IPDM E/R branch line.
