Using the SSTs

Perform the "Preparation."
Connect the SSTs (WDS or equivalent) to the data link connector-2 (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.
NOTE:
- When working with two people, one should press on the brake pedal, the other should attempt to rotate the wheel being inspected.
Send the command while pressing on the brake pedal and attempting to rotate the wheel being inspected.
When pressure is being maintained, and clock sound indicating the solenoid is operating comes from the ABS HU/CM, confirm that the wheel does not rotate. When pressure is being reduced, and clock sound indicating the solenoid is operating comes from the ABS HU/CM, confirm that the wheel rotates, even though the brake pedal is being depressed.
NOTE:
- To protect the ABS HU/CM, 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 HU/CM brake lines are normal.
  - The ABS HU/CM hydraulic system is not significantly abnormal.
  - The ABS HU/CM wiring is normal.
- However, the following items cannot be checked.
  - ABS HU/CM input system harness and parts
  - Extremely small leaks in the ABS HU/CM internal hydraulic system
  - Unusual intermittent occurrences in the above items
