System Description

The Cruise Control system enables the driver to preselect the speed of the car and then take his foot off the accelerator, leaving the system to keep the car travelling at the selected speed. The driver sets the system by means of a switch on the combined dipswitch and direction indicator stalk. The system will be disengaged automatically when either the clutch pedal or brake pedal is depressed, when the switch is moved to the OFF or TIP position, when the selector lever is in the N position or when the Traction Control System is activated on cars equipped with the B308 engine.

The Cruise Control system consists of the following components and signals:
- Control module
- Switches
- Brake and clutch pedal switches
- Brake lights switch
- Speed signal from the speedometer
- Cruise Control active signal, to the engine management system







Cars with the B308 engine
On cars equipped with the B308 engine and TCS, +30 current is supplied from the brake lights switch to pin G (7) of the Cruise Control system control module via the TCS control module. This is to enable the TCS control module to disengage the Cruise Control system if wheelspin occurs for more than one second.

Cars with Turbo
On turbo cars with the Cruise Control system, the TRIONIC control module receives a signal from pin J (9) of the Cruise Control system control module telling it that the Cruise Control system is engaged. This ensures smoother control of the car's speed.

Automatic transmission
The Cruise Control system is supplied with current from fuse 9 via the selector lever position sensor and also from fuse 2. This ensures that the system will be operative when the selector lever is any of the drive positions (D, 3, 2,1).
