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 CONSULT, instead of those from chassis control module 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: SYMBOL During an active test, sometimes a chassis control warning is displayed and the master warning lamp illuminates on the information display in the combination meter; however, this is not a malfunction.
