Diagnosis Procedure

INFOID:0000000010243517

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 ABS actuator and electric unit (control unit) 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 ABS actuator and electric unit (control unit).

2.

Check the resistance between the ABS actuator and electric unit (control unit) harness connector termi-
nals.

Is the measurement value within the specification?

YES

>> GO TO 3.

NO

>> Repair the ABS actuator and electric unit (control unit) branch line.

3.

CHECK POWER SUPPLY AND GROUND CIRCUIT

Check the power supply and the ground circuit of the ABS actuator and electric unit (control unit). Refer to

BRC-77, "Diagnosis Procedure"

.

Is the inspection result normal?

YES (Present error)>>Replace the ABS actuator and electric unit (control unit). Refer to 

BRC-113, "Exploded

View"

.

YES (Past error)>>Error was detected in the ABS actuator and electric unit (control unit) branch line.
NO

>> Repair the power supply and the ground circuit.

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.
• Models with Intelligent Key: 

PCS-20, "Diagnosis Procedure"

• Models without Intelligent Key: 

PCS-49, "Diagnosis Procedure"

Is the inspection result normal?

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

• Models with Intelligent Key: 

PCS-34, "Exploded View"

• Models without Intelligent Key: 

PCS-64, "Exploded View"

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

>> Repair the power supply and the ground circuit.
