At the end of the direction indicator stalk switch, there is a spring-loaded push-button. When the button is pressed, connection B will be energized. This position has two functions:

Engage cruise control and store the current speed in memory irrespective of whether any other speed has previously been stored there.
The speed increases if the button is pressed. Once the button is released, the current speed will be stored and cruise control continues.

If the button is pressed for a shorter time than 300 ms, the requested speed is increased by 1.6 km/h (1 mph).

Brake light switch = 0
Clutch and brake pedal switches = 0
Speed, wire from ABS 40 km/h.
Speed, bus from MIU 40 km/h.

Brake light switch and clutch/brake pedal switches simultaneously = 1 at some time during this driving cycle.
No diagnostic trouble code blocking throttle control.
Inputs A, B and C = 0 prior to switch being moved to ON/OFF.
Cruise control engaged with switch.
