CRUISE CONTROLB5
CIRCUIT OPERATION1
CIRCUIT OPERATION
Petrol Engine
For vehicles equipped with a manual transmission,
cruise control can only be activated when the Cruise
Control Switch (X115) is depressed, the transfer
gear box is in Hi range, and the clutch pedal is not
depressed. Also, the BeCM (Z238) will deactivate
cruise control if the engine rpm rises above 5000 +
10%, due to the possibility of selecting gears
manually without the use of the clutch.
For vehicles equipped with an automatic...

CIRCUIT OPERATION2
System Disable
The cruise control system can be disabled in one of
four ways:
8. The Cruise Control Switch (X115) is put in the 0
position, removing the BeCM (Z238) power from
the Cruise Control ECU (Z121) and vacuum
pump, and erasing the set speed memory.
9. The RES/DECEL Switch is depressed, signalling
the Cruise Control ECU (Z121) via the Inverter/
Converter (Z249) to disengage the system.
10. The brake pedal is depressed and a vacuum val-

CIRCUIT OPERATION3
SET/ACCEL
To set a cruise speed, the Cruise Control Switch
(X115) must be on and vehicle speed must exceed
28 mph (45 km/h). When the SET/ACCEL Switch is
depressed under these conditions, the
Inverter/Converter (Z249) is suppplied with a ground
signal. This signal is transmitted via the OY wire to
the Engine Control Module (ECM) (Z132) causing
the vehicle to accelerate. When the SET/ACCEL
Switch is released, the signal is removed signalling
the Engine Control Module...
