Do the brake pad inspection: Front (except
Type S model) (see page 19-12), front (Type S
model) (see page 19-15), rear (see page 19-29),
check for brake fluid leaks or replace worn brake
pads,thengotostep2,andrecheck.
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.

modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.
Go to step 9. 9. Check the BRAKE FLUID LEVEL SWITCH in the VSA
DATA LIST with the HDS.
Substitute a known-good gauge control
module (tach), then go to step 1, and recheck. If no
DTCs are indicated, replace the original gauge
control module (tach) (see page 22-277).
Go to step 10.
10. Disconnect the brake fluid level switch 2P connector, then check the BRAKE FLUID LEVEL
SWITCH in the VSA DATA LIST.
Replace the brake master cylinder (the brake
fluid level switch is included) (see page 19-24).

1. Test-drive the vehicle.
NOTE: Drive the vehicle on the road, not on a lift.
2. Turn the ignition switch to LOCK (0).
3. Raise the vehicle, and support it with safety stands in the proper locations (see page 1-11).
4. Turn all four wheels by hand.
Repair the brake drag.
Go to step 5.
5. Turn the ignition switch to ON (II).
6. Check the BRAKE PRESS in the VSA DATA LIST with the HDS while moving the brake pedal.
Intermittent failure, the system is OK at this
time.
Replace the VSA modulator-control unit
(see page 19-171). 1. Start the engine.
2. Check the BRAKE PRESS in the VSA DATA LIST
with the HDS. Do not press the brake pedal.
Go to step 3.
Check for brake drag or a misadjusted brake
pedal position switch. If they are normal, replace
the VSA modulator-control unit (see page 19-171).
3. Check the BRAKE SWITCH in the VSA DATA LIST with the HDS while moving the brake pedal.
Intermittent failure, the system is OK at this
time. Check for loose terminals between the brake
pedal position switch 4P connector, ECM/PCM

Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then go to
step 1, and recheck. If the ECM/PCM was updated
and DTCs are not indicated, troubleshooting is
complete. If the ECM/PCM was substituted and
DTCs are not indicated, replace the original ECM/
PCM (see page 11-228).
