| Component part | Function |
| Vehicle-speed sensor, ESP/ABS Control Module | Converts vehicle speed to pulse. |
| ECM | Receives signals from sensor and control switches. |
| Cruise control indicator | Illuminates when CRUISE main switch is ON (Built into cluster) |
| Cruise Control switches | CRUISE switch | Switch for automatic speed control power supply. |
| Resume/Accel switch (RES +) | Controls automatic speed control functions by Resume/Accel switch (Set/Coast switch) |
| Set/Coast switch (RES -) | |
| Cancel switches | Cancel switch | Sends cancel signals to ECM. |
| Brake-pedal switch | |
| Transaxle range switch (A/T) | |
| ETS Motor | Regulates the throttle valve to the set opening by ECM. |

Inspection 1. Ignition "ON". 2. Turn on the head lamp switch. 3. Check that the aim of the head lamp changes smoothly when the head lamp leveling device switch is turned on. 4. If it does not operate well, check the connector and terminals to make sure that they are connected.
Description The ambient temperature sensor is located inside the side mirror and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperature. The sensor output will be used for discharge temperature control, temperature regulation door control,
