Hydraulic Unit: Testing and Inspection
ABS HYDRAULIC UNIT INSPECTION
System Inspection
1. Verify that the battery is fully charged. With the ignition switch at ON, verify that the ABS warning light goes out after 2 - 4 seconds.
2. If the light stays ON after 2 - 4 seconds the control module detects a failure and will not activate the hydraulic unit. Follow the troubleshooting
procedures.
3. Turn the ignition switch to OFF.
4. On level ground, jack up the vehicle and support it evenly on safety stands. Shift the transaxle to neutral or N range.
5. Release the parking brake.
6. Rotate the wheels by hand, and inspect for brake drag.
CAUTION:
^
Connecting the wrong terminals may possibly cause a malfunction. Carefully connect the specified terminals only.
7. Using a jumper wire, connect the TBS and GND terminals of the data link connector.
8. Depress the brake pedal, and have an assistant verify that the right front wheel will not turn.
9. With the brake pedal still depressed, turn the ignition switch to ON and verify that the brake is released momentarily (approx. 0.5 sec.) and that the
wheel turns when pressure-reduction operates.
