5. Measure the voltage between brake pedal position

switch 4P connector terminal No. 1 and body
ground.

Go to step 6.

Repair open in the wire between the No. 13

(20 A) fuse in the under-hood fuse/relay box and
the brake pedal position switch.

6. Turn the ignition switch OFF, and jump the SCS line

with the HDS.

NOTE: This must be done to protect the powertrain
control module (PCM) from damage.

7. Disconnect PCM connector A (44P).

8. Measure the voltage between PCM connector

terminal A8 and body ground.

Substitute a known-good PCM (see page

11-8), and recheck.

Repair open in the wire between the brake

pedal position switch and the PCM (A8).

9. Clear the DTCs with the HDS (see page 19-41).

10. Turn the ignition switch OFF, then turn it ON (II),

and press the brake pedal several times.

11. Check for DTCs with the HDS (see page 19-41).

Go to step 12.

The system is OK at this time.

12. Check BRK PRESS in the VSA DATA LIST with the

HDS.

Replace the VSA modulator-control unit

(see page 19-94).

Check the brake lines for damage and

leakage.

1. Check for DTCs with the HDS.

Troubleshoot DTCs 91 or 92 and recheck.

Go to step 2.

2. Put the vehicle on a level surface, and center the

steering wheel spokes.

3. Check the STEERING ANGLE in the VSA DATA LIST

with the HDS.

Go to step 4.

Check for installation of the steering angle

sensor. If installation is good, do the steering angle
sensor center point writing.

4. Check the wheel alignment (see page 18-5).

Go to step 5.

Make sure the suspension is not modified,

and adjust the wheel alignment correctly, and
recheck by test-driving.

5. Clear the DTCs with the HDS (see page 19-41).

6. Turn the ignition switch OFF, then disconnect the

HDS.

7. Test-drive the vehicle around a number of corners.

8. Connect the HDS, and check for DTCs with the HDS

(see page 19-41).

Replace the VSA modulator-control unit

(see page 19-94).

Intermittent failure; the most probable cause

is that the vehicle has driven on an extremely
sloped road. The system is OK at this time.

1. Disconnect the yaw rate-lateral acceleration sensor

4P connector.

2. Turn the ignition switch ON (II).

3. Measure voltage between body ground and yaw

rate-lateral acceleration sensor 4P connector
terminal No. 1.

Go to step 5.

Repair open or high resistance in the wire

between the No. 31 (7.5 A) fuse in the under-dash
fuse/relay box and the yaw rate-lateral acceleration
sensor.

4. Turn the ignition switch OFF.

5. Reconnect the yaw rate-lateral acceleration sensor

4P connector.

6. Clear the DTCs with the HDS (see page 19-41).

7. Turn the ignition switch OFF, then turn it ON (II).

8. Check for DTCs with the HDS (see page 19-41).

Check for loose terminal in the yaw rate-

lateral acceleration 4P connector. If connection is
good, replace the VSA modulator-control unit
(see page 19-94).

Intermittent failure, the system is OK at this

time. Check for loose or poor connections.

Failure)

1. Connect the HDS to the DLC (see page 19-41).

2. Turn the ignition switch ON (II).

3. Check YAW RATE S in the VSA DATA LIST with the

HDS.

Go to step 4.

Check the installation of the yaw rate-lateral

acceleration sensor. Replace the yaw rate-lateral
acceleration sensor (see page 19-92).

4. Clear the DTCs with the HDS (see page 19-41).

5. Turn the ignition switch OFF, then disconnect the

HDS.

6. Test-drive the vehicle around a number of corners.

7. Connect the HDS, and check for DTCs with the HDS

(see page 19-41).

Go to step 8.

poor road surface. The system is OK at this time.

8. Substitute a known-good yaw rate-lateral

acceleration sensor (see page 19-92).

9. Clear the DTCs with the HDS (see page 19-41).
