DATA MONITOR
















The stroke sensor is composed of two circuits: stroke sensor 1 and stroke sensor 2.

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 electrically-driven intelligent brake 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.
- Brake warning lamp (red) and brake system warning lamp (yellow) turn ON during active test. This is not a malfunction.
