Active Test

The active test is used to determine and identify details of a malfunction, based on self-diagnosis test result sand data obtained in the DATA MONITOR. In response to instructions from CONSULT, instead of those from ABS actuator and electric unit (control unit) on the vehicle, a drive signal is sent to the actuator to check its operation.

CAUTION:
  • Never perform ACTIVE TEST while driving the vehicle.
  • Always bleed air from brake system before active test.
  • Never perform active test when system is malfunctioning.
NOTE:
  • When active test is performed while depressing the pedal, the pedal depressing stroke may change. This is not a malfunction.
  • "TEST IS STOPPED" is displayed Approx. 10 seconds after operation start.
  • When performing active test again after "TEST IS STOPPED" is displayed, select "BACK".
  • ABS warning lamp, brake warning lamp and VDC warning lamp may turn ON during active test. This is not a malfunction.
