Testing and Troubleshooting

Fan Control

With all connections made disconnect ArduAudi chassis ground brown wire. Switch ignition to on and ensure fans turn on high after approximately 2-8 seconds. Reconnect ArduAudi chassis ground wire. Switch ignition to on and the fans should remain off (unless the car is warm and coolant temp is high in which case the fans may come on low/medium/high for a few minutes).

Cruise Control

Switch ignition to on and monitor channel 66 on the ecu via VAG-Com. Cycle the cruise stalk, on/off/set/retard/cancel/resume and take note of the changing values. Ensure your ecu is seeing speed/brake/clutch signals via channel 66. Reference this ross-tech link for more info.
