1. Turn the ignition switch to ON (II).
2. Check the BRAKE PRESS in the VSA DATA LIST
with the HDS. Do not press the brake pedal.
Check the brake pedal height and the brake
pedal position switch adjustment (see page 19-6). If
the brake pedal height is OK, replace the VSA
modulator-control unit and the brake pedal position
switch adjustment (see page 19-171).
Go to step 3.
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.
Go to step 4.
4. Check the BRAKE SWITCH in the VSA DATA LIST with the HDS, and disconnect the brake pedal
position switch 4P connector.
Inspect the brake pedal switch and
adjustment (see page 19-6). If the switch and
adjustment are OK, replace the brake pedal
position switch (see page 19-6).
Go to step 5. 5. Turn the ignition switch to LOCK (0).
6. Short the SCS line with the HDS.
7. Disconnect ECM/PCM connector A (44P).
8. Turn the ignition switch to ON (II).
9. Measure the voltage between brake pedal position
switch 4P connector terminal No. 2 and body
ground.
Repair short to power in the wire between
the ECM/PCM and the brake pedal position
switch.
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).
