Detection
The DTC is set active if the CAN message CUVInformation-V has been absent for 5000 ms. The DTC is set inactive when the CAN-message CUVInformation-V is received. The DTC is not set in the following cases: • ignition is turned off • first 2 seconds after ignition on • system voltage is below 22 volt • system voltage is above 30 volt • short circuit or open circuit on the CAN bus (separate DTCs)
Possible cause
• Faulty CUV unit • CUV unit disconnected from the CAN bus
