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
No system-reaction text recorded.
Diagnostic depth
Communication error. Communication with the Tachograph System (TCO) interrupted.
• Faulty TCO unit • TCO unit disconnected from the yellow CAN bus
