Actuator Test
This mode is used to exercise the ABS actuators and make sure they operate normally. Prior to the test, pay attention to the cautions below. (When checking the solenoid valve system, be sure to jack up the vehicle.)
- Before testing, be sure that the brakes work normally.
- Make sure that the battery is fully charged. Conduct the test by two persons (A TECH 2 operator and a vehicle checker).
