IPDM-E Branch line circuit
IPDM-E Branch line circuit
Diagnosis Procedure
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the IPDM E/R for damage, bend and loose connection (unit side and connector side).
Is the inspection result normal?
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 the following.
- With Intelligent Key system: PCS "Diagnosis Procedure"
- Without Intelligent Key system: PCS"Diagnosis Procedure"
Is the inspection result normal?
YES (Present error)>>Replace the IPDM E/R. Refer to the following.
- With Intelligent Key system: PCS "Removal and Installation"
