Detection
The EHS does not recieve communication, detected by not getting valid communication from CAN for 5x200ms. This indicated that the CAN communication is not present. This DTC unsets if we get a valid speed command. The EHS does not set this DTC code for the first 2000 ms if the voltage is lower than 22V or greater than 32V, which may be cause by cranking.
