PROBLEM SYMPTOMS TABLE

If there are no DTCs output but the problem still occurs, check the circuits for each problem symptom in the

order given in the table below and proceed to the relevant troubleshooting page.

CAUTION:

When replacing the brake ECU, sensor, etc., make sure that the ignition switch is turned OFF, the stop

lamp switch is off, and 2 minutes have elapsed since the driver

′s door was closed.

NOTE:

• Inspect the fuse and relay before investigating the suspected areas shown in the table below.

• Inspect each malfunctioning circuit in numerical order for the corresponding symptom.

• Since the oil passage is blocked off by the master cut solenoid during Electronically Controlled Brake con-

trol, there is no kickback (vibration) to the brake pedal, creating a quiet operating sound even while the ABS

is operating.

Symptom

Suspected area

ABS and/or EBD does not operate

Use a chassis dynamometer, etc. to check
the Electronically Controlled Brake opera-
tion.

—

Check the DTC again and make sure that
the normal system code is output.

IG power source circuit

BRC-83, "Description"

Front wheel sensor circuit

Rear wheel snesor circuit

Check the brake actuator assembly with
the CONSULT-III. (Check brake actuator
assembly operation using the Active Test
function.) If abnormal, check the hydraulic
circuit for leakage.

BRC-194, "Inspection"

If the symptoms still occur even after the
above circuits in suspected areas have
been inspected and proved to be normal,
replace the brake ECU.

—

ABS and/or EBD does not operate efficient-
ly

Check the DTC again and make sure that
the normal system code is output.
