DTC 76

DTC 76 BRAKE SWITCH "A" CIRCUIT

CIRCUIT DESCRIPTION

DTC Detection Condition:

The ECM receives the brake demand signal from the cruise control ECU (distance control ECU) and transmits it to the ABS & traction actuator assy (skid control ECU).

The ABS & traction actuator assy (skid control ECU) receives a signal from the ECM and operates the brake actuator.

The ABS & traction actuator assy (skid control ECU) operates the brake actuator and illuminates the stop lamp by operating the BRK relay at the same time.
