Diagnosis Procedure

INFOID:0000000009718355

1.

CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY AND GROUND CIR-

CUIT

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

BRC-89, "Diagnosis Procedure"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

CHECK VDC OFF INDICATOR LAMP SIGNAL (1)

1.

Select “ABS”, “DATA MONITOR” and “OFF LAMP” according to this order with CONSULT.

2.

Turn the ignition switch OFF.

3.

Check that data monitor displays “On” for approx. 1 second after ignition switch is turned ON, and then
changes to “Off”.

CAUTION:

Never start engine.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Replace ABS actuator and electric unit (control unit). Refer to 

BRC-127, "Exploded View"

.

3.

CHECK VDC OFF INDICATOR LAMP SIGNAL (2)

1.

Select “ABS”, “DATA MONITOR” and “OFF LAMP” according to this order with CONSULT.

2.

Check that data monitor displays “On” or “Off” each time when VDC OFF switch is operated.

Is the inspection result normal?

YES

>> Check the combination meter. Refer to 

MWI-34, "Diagnosis Description"

.
