TCO node: timeout in CAN communication.
• Check the TCO for DTCs. • If DTCs cannot be read from the TCO: - check CAN connection to TCO unit - check power supply and ignition signal to the TCO • 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
• Functions dependent on information from TCO are degraded (examples listed below): - The vehicle speed display in the ICL will be absent - The vehicle distance display in the ICL will be absent Cruise control is disabled Adaptive Cruise control is disabled Downhill speed control is disabled
System reaction
Amber Cruise Control malfunc.
Diagnostic depth
Communication error. Communication with the Tachograph System (TCO) interrupted.
• Faulty TCO unit • TCO unit disconnected from the yellow CAN bus
