ACTIVE TEST
The active test is used to determine and identify details of a malfunction, based on self-diagnosis test results and data obtained in the data monitor. In response to instructions from M.U.T.-III SE, 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
  • “TEST IS STOPPED” is displayed approximately 10 seconds after operation start.
  • When performing active test again after “TEST IS STOPPED” is displayed, select “BACK”.
  • ABS warning light, brake warning light and ASC warning light may turn ON during active test. This is not a malfunction.
