TimeDate - Missing message
Check the ICL for DTCs. • If DTCs cannot be read from the ICL: - check CAN connection to ICL and COO unit - check power supply and ignition signal to the ICL, COO and DAS (vehicles with DAS). • Check wiring and connectors for the Yellow CAN bus, Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) and CAN5 bus (vehicles with DAS). • Measure the resistance (with the battery disconnected) at Yellow CAN bus, Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) and CAN5 bus (vehicles with DAS). 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 ICL are degraded. Examples listed below. - timestamp for DTC
Diagnostic depth
The DTC is set active if the CAN message TimeDate_ICL has been absent for 5000 ms.
• Faulty ICL, COO unit or DAS (vehicles with DAS). • Open circuit on the Yellow CAN bus, Environment Sensor CAN bus (vehicles without DAS), Sensor CAN bus (vehicles with DAS) or CAN5 bus (vehicles with DAS).
