System Components
BRAKES SYSTEM COMPONENTS DESCRIPTION
| Component parts | Description |
|---|---|
| Wheel sensor | Senses or detects each wheel rotation speed. |
| ABS/TCS control unit | Receives signals from all wheel sensors and sends a control signal to TAC module, ECM and TCM. If electrical system becomes inoperative, fail-safe function will activate, operating the vehicle similar to a vehicle which is not equipped with TCS. |
| ABS/TCS control unit | When fail-safe function activates, TCS OFF indicator and TCS SLIP indicator light. These indicators are located in the meter cluster. The self-diagnostic function supports the CONSULT-II. The self-diagnostic result is also indicated by the SLIP indicator. |
| TAC module | Receives a signal from ABS/TCS control unit in order to control throttle actuator. Throttle motor operation will then be controlled for regulating throttle positioning. |
| TAC module | If throttle motor control system becomes inoperative, throttle motor operation will be suspended. TAC module will then activate fail-safe function. The self-diagnostic result is indicated by the control unit LED. The self-diagnostic function supports the CONSULT-II. |
| Throttle actuator | Receives a signal from TAC module and activates throttle motor. |
| ECM | Receives a signal from ABS/TCS control unit and provides fuel-cut control. This in turn regulates engine drive torque. |
| TCM | Receives a signal from ABS/TCS control unit and provides shifting control. |
| SLIP indicator | Lights in conjunction with TCS operation. Also indicates self-diagnostic result for TCS. |
| TCS OFF indicator | Lights when TCS is "OFF" (TCS switch "ON"), indicating that TCS is not operating. |
| TCS OFF switch | Set to "ON" to deactivate TCS. |
