RTC node: timeout in CAN communication.
• Check the RTC for DTCs • If DTCs can not be read from the RTC: - check CAN connection to RTC unit - check power supply and ignition signal to the RTC • 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 RTC are degraded. Examples listed below. - Cruise Control with Active Prediction
Diagnostic depth
Communication error. Communication with the Road Telematic Communicator (RTC) interrupted.
• Faulty RTC unit • RTC unit disconnected from the yellow CAN bus.
