Using The SSTS

Perform the "Preparation". See PREPARATION .
Connect the WDS or equivalent to DLC-2.

Set up an active command mode inspection according to the combination of commands below. See ABS ON-BOARD DIAGNOSIS .

The chart above shows an example of a right wheel inspection.
Send the command while pressing on the brake pedal and attempting to rotate the wheel being inspected.
When pressure is being maintained, and click sound indicating the solenoid is operating comes from the ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS), confirm that the wheel does not rotate. When pressure is being reduced, and click sound indicating the solenoid is operating comes from the ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS), confirm that the wheel rotates, even though the brake pedal is being depressed.

NOTE:

When working with two people, one should press on the brake pedal, the other should attempt to rotate the wheel being inspected.
To protect the ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS), the solenoid valve used for simulations and the ABS motor stay on for 10 seconds each time they are switched on.
Performing the inspections above determines the following.
- The ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS) brake lines are normal.
- The ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS) hydraulic system is not significantly abnormal.
- The ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS) wiring is normal.
However, the following items cannot be checked.
- ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS) input system harness and parts
- Extremely small leaks in the ABS/TCS HU/CM (with TCS) or ABS HU/CM (without TCS) internal hydraulic system
- Unusual intermittent occurrences in the above items 1 through 3
