NOTE
The diagnosis modes are for testing all components and functions of the
cruise control. The cruise control uses an internally generated reference
signal to test the electric module in diagnosis mode B.
If the cruise control does not work after diagnosis mode B is completed,
there is generally a problem recording the travel speed signal.
Diagnosis mode A
Diagnosis mode A tests the electronic components and electrical connections.
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.
