This function is used to check the components communicating with the climate control module (CCM) via LIN bus 1 and LIN bus 2. A diagnostic trouble code (DTC) between CCM-0070 and CCM-0072 will be stored, depending on the fault, if there is a fault in one of the LIN buses. These diagnostic trouble codes (DTCs) can only be stored for this diagnostic function.
