CUV node: timeout in CAN communication
• Check the CUV for DTCs. • If DTCs cannot be read from the CUV: - check CAN connection to CUV unit - check power supply and ignition signal to the CUV • Check wiring and connectors for the yellow CAN-bus • Measure the resistance (with the battery disconnected) between pins B2 and B11. It should be approximately 60 ohm (one 120 ohm termination resistor in each end of the CAN-bus).
What you'll see
No driver-visible symptom recorded.
System reaction
• Functions dependent on information from CUV are degraded (examples listed below): - No main beam indication on ICL. - No direction indication on ICL. - The active light warning might stop to work even though ignition is turned off and lights are on.
Diagnostic depth
Communication error. Communication with the Visibility System (CUV) interrupted.
• Faulty CUV unit • CUV unit disconnected from the yellow CAN bus
