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-61, "Diagnosis Procedure"

.

Is the inspection result normal?

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

BRC-109, "Removal

and Installation"

.

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.

Diagnosis Procedure

INFOID:0000000009760144

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-30, "Diagnosis Procedure"

• Without Intelligent Key system: 

PCS-59, "Diagnosis Procedure"

Is the inspection result normal?

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

• With Intelligent Key system: 

PCS-31, "Removal and Installation"

• Without Intelligent Key system: 

PCS-60, "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.
