Cruise Control Switch: Description and Operation

COMMAND SWITCH (CRUISE CONTROL LEVER)




- When the vehicle is driven with the cruise control activated, the command switch controls its operation. It inputs MAIN signal, SET/COAST signal, ACCEL/RESUME signal or CANCEL signal to the engine control module (ECM).
- When the cruise control MAIN switch is turned ON, the cruise set indicator light in the combination meter illuminates. Also, when the cruise control is set, the cruise indicator light in the combination meter illuminates.
- The command switch is located on the right side of the steering wheel, so the driver can operate it without releasing hands from the steering wheel.
- The command switch is a self-returning lever type.

1. MAIN SWITCH
When the switch is pushed once the cruise control system turns ON and becomes ready to set the cruise control. When the switch is pushed again the cruise control turns OFF.

2. RESUME/ACCEL AND SET/COAST SWITCH
Each switch contact is held closed as long as the lever is kept pressed in the relevant direction and resulting current is applied as a signal to the engine control module (ECM).

3. CANCEL SWITCH
All the switch contacts are closed as long as the lever is pulled toward the CANCEL position (toward the driver). This causes the RESUME/ACCEL and SET/COAST ON signals to be sent to the engine control module (ECM) simultaneously.

CANCEL SIGNALS
The cancel signal deactivates the cruise control function. Operating any of the following switches results in generation of the cancel signal. On receiving the signal, the engine control module (ECM) cancels the cruise control function.
- Stop light switch
- Brake switch
- Clutch switch
- Neutral switch
- MAIN switch (OFF operation)
- Command switch (CANCEL position)
- Ignition switch (OFF operation)
