- For vehicles with automatic climate control: if wiring is OK, check the
TIM signal (standing time signal) with the ABS control module
connected and disconnected using the measuring value blocks for the
A/C control module -J301-. If the signal is recognized by the A/C
control module -J301-, replace the ABS control module -J104-.
