PROCEDURE

1.INSPECT NO. 1 PARKING BRAKE WIRE ASSEMBLY

Turn the ignition switch off.

Make sure that there is no looseness at the locking part and the connecting part of the connectors.

OK:: The connector is securely connected.

Disconnect the oO3 and o1 No. 1 parking brake wire assembly connectors.

Check both the connector case and the terminals for deformation and corrosion.

OK:: No deformation or corrosion.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
oO3-1 or o1-2 (+) - Body ground and other terminals	Always	10 kΩ or higher
oO3-2 or o1-1 (-) - Body ground and other terminals	Always	10 kΩ or higher

Result:

Proceed to
OK
NG

2.CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU (BRAKE ACTUATOR ASSEMBLY) - PARKING BRAKE ACTUATOR ASSEMBLY RH)

REPLACE NO. 1 PARKING BRAKE WIRE ASSEMBLY

2.CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU (BRAKE ACTUATOR ASSEMBLY) - PARKING BRAKE ACTUATOR ASSEMBLY RH)

Turn the ignition switch off.

Make sure the No. 1 parking brake wire assembly is securely installed.

Disconnect the A51 skid control ECU (brake actuator assembly) connector.

Disconnect the o1 parking brake actuator assembly RH connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A51-2 (MRR+) or o1-2 (+) - Body ground	Always	10 kΩ or higher
A51-3 (MRR-) or o1-1 (-) - Body ground	Always	10 kΩ or higher

Result:

Proceed to
OK
NG
