HYDRAULIC MODULE INSPECTION

CAUTION: Turn the ignition switch off before connecting or disconnecting the Hi-Scan.

1. Jack the vehicle up and support the vehicle with rigid racks at the specified jack-up points or replace the wheels which are checked on the rollers of the braking force tester.

CAUTION:
1. The roller of the braking force tester and the tire should be dry during testing.
2. When testing the front brakes, apply the parking brake, and when testing the rear brakes, stop the front wheels by chocking them.

2. Release the parking brake and feel the drag force (drag torque) on each road wheel.
When using the braking force tester, take a reading of the brake drag force.
3. Turn the ignition key "OFF" and set the Hi-Scan or Hi-Scan Pro as shown in the diagram.
4. After checking that the shift lever or the selector lever is in neutral, start the engine.

NOTE: If the ABS is in fail-safe mode, the Hi-Scan actuator test cannot be used.

5. Use the Hi-Scan to force-drive the ABS actuator.
