Checking for a short-circuit
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can occur for a number of different reasons. The fault is evaluated depending on how it occurs.
Check the signal cable between control module terminal #A2 and seat motor 1. Check for a short-circuit to ground.
Check the signal cable between control module terminal #A3 and seat motor 2. Check for a short-circuit to supply voltage.
Check the signal cable between control module terminal #A4 and seat motor 3. Check for a short-circuit to ground.
Check the signal cable between control module terminal #A5 and seat motor 4. Check for a short-circuit to ground.
Check the signal cable between control module terminal #A6 and the seat motors. Check for a short-circuit to ground.
