Diagnostic Mode Operation - Honda Goldwing GL1200 Installation Manual

The yellow ignition sensor wire should be run forward with the
cruise loom to the left hand ignition coil which is directly behind
the steering head. The coil has two wires going to it, one blue
with a yellow trace and one black wire with a white trace.
Remove the blue/yellow wire and place the yellow ignition
sensor wire on this terminal. Plug the blue/yellow wire on to the
'piggy back' spade on the sensor wire terminal. If the coil wire is
not blue/yellow, find out which wire to the coil is the 'active
• Ensure that all the wires are routed neatly and cable tie if required.
• Reassemble the bike taking care when installing the top compartment cover (dummy fuel tank) not to jam or
distort the new carburettor cable or the throttle cable.

DIAGNOSTIC MODE OPERATION

Your cruise control comes with a means of making it operate the throttle without the speed sensor detecting
movement. This is the best way to check that the electrical and mechanical operation of the cruise control is
working properly - excluding speed control circuits.
Note:- During the diagnostic checks many of the features of the cruise control are confirmed by the LED (light)
on the computer operating. For example, brake switch operation is confirmed by the LED. The LED only stays
on for a few seconds with most operations. If the brake pedal is pushed, the LED will come on. If the pedal is
held after a few seconds the LED will go out. If the pedal is released and re-applied, the LED will come back
on, and then turn off after a few seconds. THIS IS NORMAL AND DOES NOT INDICATE A FAULT IN
THE SPEED CONTROL. This applies to most operations performed in diagnostic mode.
• Turn the cruise control ON/OFF switch to OFF;
• Turn the ignition switch ON but DO NOT start the engine. Check that the kill switch is also ON.
• Depress and hold the SET key while turning the cruise control ON;
• Take your finger off the SET key;
• Pull the front brake lever and depress the rear brake pedal a few times. The LED on the computer should
illuminate when EITHER lever is used. This indicates that the cruise control will cancel when the brakes are
applied. If the LED does not come on, the most likely cause is incorrect adjustment of the brake switches. If
either of the switches is adjusted so that it does not turn OFF at all, the light WILL NOT COME ON AT
ALL. It is then necessary to adjust the switch so that it turns OFF when the brake is released. IF THE
BRAKE SWITCH OPERATION IS NOT CONFIRMED BY THE LED OPERATING ON THE
COMPUTER NOTHING ELSE WILL WORK ON THE CRUISE CONTROL. See the next section.
• Now tap the SET key once while listening for a click from the vacuum actuator and watching the red LED on
the front of the computer. You should hear the click and see the LED flash. Depress and hold the SET key.
The LED should come on a stay on while the SET key is depressed and regular clicks should be heard from
the actuator.
• Now tap the RES key once while listening for a click from the vacuum actuator and watching the red LED
on the front of the computer. You should hear a slightly different sounding click and see the LED flash.
Depress and hold the RES key. The LED should come on a stay on while the RES key is depressed and
regular clicks should be heard from the actuator.
