Open-Circuit

Open-circuit

Checking the component
The control module has registered an open-circuit in the signal to one of the control panels in the door.
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 that the control panels are connected correctly.
DDM-0010
- Check the signal cable between control module terminal #A16 (#16) and control panel for the central locking terminal #4. Check for contact resistance. Check for an open-circuit
- Check the signal cable between the control panel for central locking terminal #5 and the control panel for power window mechanism terminal #10. Check for contact resistance. Check for an open-circuit
- Check the signal cable between control module terminal #A16 (#16) and the control panel for power window mechanism terminal #10. Check for contact resistance. Check for an open-circuit.
PDM-0010
- Check the signal cable between control module terminal #A16 (#16) and control panel for the central locking terminal #4. Check for contact resistance. Check for an open-circuit
- Check the signal cable between the control panel for central locking terminal #5 and the control panel for power window mechanism terminal #1. Check for contact resistance. Check for an open-circuit
- Check the signal cable between control module terminal #A16 (#16) and the control panel for power window mechanism terminal #1. Check for contact resistance. Check for an open-circuit.
