2.

READ VALUE OF CONSULT-III (ACCUMULATOR PRESSURE SENSOR)

1. Turn the ignition switch OFF.

2. Connect the CONSULT-III.

3. Turn the ignition switch ON.

4. Select the “DATA MONITOR” on the CONSULT-III.

ABS/VDC:

5. Depress the brake pedal 4 or 5 times to operate the pump motor, and check the output value on the CON-

SULT-III with the motor stopped (not braking).

NOTE:

Accumulator pressure sensor voltage does not drop.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace brake actuator assembly.

3.

RECONFIRM DTC

1. Turn the ignition switch OFF.

2. Clear the DTC.

3. Perform the road and braking test.

4. Check if the same DTC is recorded.

Result

A

>> Check for intermittent problems (symptom simulation).

B

>> Replace brake ECU.

Diagnosis Procedure

INFOID:0000000004212725

CAUTION:

When replacing the brake ECU, perform initialization of linear solenoid valve and calibration.

1.

CHECK FREEZE FRAME DATA

Check the INF cord from the Freeze Frame Data memorized when the DTC (C1377) is stored.

Result

A

>> GO TO 2.

B

>> Replace brake capacitor.

C

>> GO TO 9.

2.

INSPECT ABS MAIN NO.3 FUSE

1. Remove the ABS No.2 fuse from the engine room R/B.

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

CAPACITOR

Brake capacitor is deteriorated (indicates a 
need to replace).

• Brake capacitor

102

Self discharge (current leak) is excessive (in-
ternal malfunction).

103

Overvoltage (16.4 V or more) continues to be 
applied from the auxiliary battery to the brake 
capacitor voltage input (+BC) for 10 seconds 
or more.

• Apply high voltage
