Does the display change to day and night modes When turning the headlights on and off?
YES - The system is OK at this time.
NO - Go to step 3.
2. Go into the Diagnostic mode, and use the "Car Status" diagnostic to check for an ILL signal.
Is the "ILL" signal OK?
YES - Go to step 3.
NO - Check the ILL+ circuit for an open or short to ground between the navigation unit and small light relay. If OK, substitute a known-good navigation unit and recheck.
3. Go into the Diagnostic mode and use the Navi System Link diagnostic to check the Air-Con link.
Is the Air-Con link red?
YES - Check the A/C-SI, A/C-SO, and A/C CLK circuits between the HVAC unit and the navigation unit for open or short to ground. If the circuits are OK, substitute a known-good HVAC unit, then the navigation unit until the problem goes away. Replace the original faulty component.
