Possible causes of fault

NOTE: Cyclical monitoring and comparison of the terminal 15 digital signal (KESSY control module) received via CAN comfort and the incoming terminal 15 analogue signal (KESSY control module) is performed in the vehicle electrical system control module. If different comparison values are detected, a fault is stored in the fault memory.

'implausible signal' Compares the incoming terminal 15 analogue signal (KESSY control module) with the terminal 15 digital signal which the KESSY control module sends to CAN comfort.
