11. Clear the DTC with the HDS.
12. Test-drive the vehicle at 10 mph (15 km /h) or more.
13. Check for DTCs with the HDS.
Is DTCs 12, 14, 16, and/or 18 indicated? YES-Check for loose terminals in the VSA modulator-control unit 46P connector. Check for a loose connection at G202. If necessary, substitute a known-good VSA modulator-control unit (see page 19-97) and retest.
NO-
DTC 25: Yaw Rate Sensor (Sensor Unit)
DTC 26: Lateral Acceleration Sensor (Sensor Unit)
1. Turn the ignition switch OFF.
2. Substitute a known-good yaw rate-lateral acceleration sensor.
3. Turn the ignition switch ON (II).
4. Clear the DTC with the HDS.
5. Test-drive the vehicle. Drive the vehicle at 19 mph (30 km/h) or more, and go a distance of 985 ft (300 m) or more.
6. Check for DTCs with the HDS.
Is DTC 25 or 26 indicated? YES-Check for loose terminals in the VSA modulator-control unit 46P connector. Check for a loose connection at G202. If necessary, substitute a known-good VSA modulator-control unit (see page 19-97) and retest.
NO-Replace the original yaw rate-lateral acceleration sensor.
DTC 27: Steering Angle Sensor (Hardware)
1. Turn the ignition switch OFF.
2. Disconnect the steering angle sensor 5P connector.
3. Disconnect the VSA modulator-control unit 46P connector.
4. Turn the ignition switch ON (II).
5. Measure the voltage between body ground and VSA modulator-control unit 46P connector terminals No.5, No. 17, No. 32, and No. 35 respectively.
VSA MODULATOR-CONTROL UNIT 46P CONNECTOR
Is there 0.1 V or more? YES-Repair short to power in the wire between the VSA modulator-control unit and the steering angle sensor.
NO-Go to step 6.
6. Turn the ignition switch OFF.
7. Check for continuity between body ground and VSA modulator-control unit 46P connector terminals No.5, No. 17, and No. 32 respectively.
VSA MODULATOR-CONTROL UNIT 46P CONNECTOR
Is there continuity? YES-Repair short to body ground in the wire between the VSA modulator-control unit and the steering angle sensor.
NO-Go to step 8.
8. Check for continuity between the appropriate VSA modulator-control unit 46P connector terminals and steering angle sensor 5P connector terminals respectively (see table).
VSA MODULATOR-CONTROL UNIT 46P CONNECTOR
Wire side of female terminals
Is there continuity? YES-Go to step 9.
NO-Repair open in the wire between the VSA modulator-control unit and the steering angle sensor.
9. Substitute a known-good steering angle sensor.
10. Reconnect all connectors.
11. Turn the ignition switch ON (II).
12. Clear the DTC with the HDS.
13. Test-drive the vehicle around a number of corners.
14. Check for DTCs with the HDS.
Is DTC 27 indicated? YES-Check for loose terminals in the VSA modulator-control unit 46P connector. Check for a loose connection at G202. If necessary, substitute a known-good VSA modulator-control unit (see page 19-97), and retest.
NO-Replace the original steering angle sensor.
DTC 31, 32, 33, 34, 35, 36, 37, 38: ABS Solenoid
1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch OFF, then turn it ON (II) again.
4. Check for DTCs with the HDS.
Is DTC 31, 32,33,34, 35, 36,37, and/ or 38 indicated? YES-Replace the VSA modulator-control unit.
NO-Intermittent failure, the system is OK at this time. Check for a loose connection at G202.
