Synchronising with an analogue connection
NOTE
I
The diagnosis modes are for testing all components and functions
of the cruise control. The cruise control uses an internally generat-
ed reference signal to test the electric module in diagnosis mode B.
If the cruise control does not work after diagnosis mode B is com-
pleted, there is generally a problem recording the travel speed
signal.
Diagnosis mode A
Diagnosis mode A tests the electronic components and electrical connec-
tions.
The LED in the electronic module and the integrated buzzer simultaneously
show that the electric wiring and the components are working properly. When
checking the components later, it is not necessary to uncover the electronic
module, because the audible signals accompany the optical ones.
You will receive confirmation from the LEDs and the buzzer when you
activate the following signals:
SET button
RES button
Brake
Clutch switch
Neutral safety switch
Travel speed signal in teach mode
Engine speed signal in teach mode
The audible and visible signals are emitted for a maximum of ten seconds per
input to ensure that other messages are not suppressed.
If you activate one of the functions above and do not hear or see a signal:
Check the electric wiring.
Diagnosis mode B
Diagnosis mode B tests the function of the accelerator.
Apply the handbrake.
Shift the gear to neutral, or to neutral or park if it is automatic.
