>> GO TO 2.

NO

>> Repair the terminal and connector.

2.

CHECK HARNESS FOR OPEN CIRCUIT

1.

Disconnect the connector of ICC sensor integrated unit.

2.

Check the resistance between the ICC sensor integrated unit harness connector terminals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ICC sensor integrated unit branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ICC sensor integrated unit. Refer to 

CCS-80, "Diagnosis

Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the ICC sensor integrated unit. Refer to 

CCS-110, "Exploded View"

.

YES (Past error)>>Error was detected in the ICC sensor integrated unit branch line.
NO

>> Repair the power supply and the ground circuit.

Diagnosis Procedure

INFOID:0000000000964168

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 

PCS-18, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the IPDM E/R. Refer to 

PCS-33, "Exploded View"

.

YES (Past error)>>Error was detected in the IPDM E/R branch line.
NO

>> Repair the power supply and the ground circuit.
