ICL node: timeout in CAN communication.
• Check the ICL for DTCs. • If DTCs cannot be read from the ICL: - check CAN connection to ICL unit - check power supply and ignition signal to the ICL • 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 the ICL are degraded (examples listed below): - radio buttons on steering wheel might stop working. - parking brake warning (with cab door switch) might stop working. - engine radiator fan speed control (abnormal behavior)
Diagnostic depth
Communication error. Communication with the Instrument Cluster (ICL) interrupted.
• Faulty ICL • ICL unit disconnected from the yellow CAN bus
