Other switches
Brake switch
Brake switch detects brake pedal operations and then sends to engine ECU. It has dual structure with 2 combined
switches and there are brake switch 1 and 2. When these 2 signals are input, engine ECU recognizes as normal brake
signals. These switch signals are related with accelerator pedal sensor operations and used to control the fuel volume
during braking. It means there are no problems in operating accelerator pedal when the brake pedal is operated but the
fuel volume reduces if operates brake pedal while the accelerator pedal is depressed.
Clutch pedal switch
Clutch pedal switch is installed on the upper of the clutch and sends clutch pedal operations to engine ECU. Contact
type switch allows engine ECU to recognize the shifting points to correct the fuel volume. It means it corrects fluctuation
happens during gear shifting. Another different function is canceling auto cruise function if equipped (auto cruise control
- equipped for export).
