* DIM = Driver Information Module
If the Parking Assistance System (PAS) is not working and there is a message in DIM about “Parking
Assistance System service required”, then it is possible that there is water ingress into front/rear park
assist sensors and connectors caused by splices in the front/rear cable harness.
A new splice type and process improvement has been introduced in supplier production from 2018-06-
06. See attached date marking on cable harness “Label PAS harness.jpg”. This will be implemented in
factory production between 2018w36 and 2018w38 depending on vehicle option variants.
If the sensors and/or connectors are found to have water ingress then follow advice under service.
SERVICE:
Follow VIDA method for loosening the bumper skin. Disconnect all connectors to the parking sensors
and connectors within the engine/luggage compartment to visually check if there is water ingress and/or
corrosion.
If water or corrosion is found:
1. Replace the cable harness.
Note: The cable harness is only in one version, it is important to install plugged connectors P/N
31412936 in all empty positions in the cable harness that are not used.
2. Replace any affected parking sensors and connectors/terminals within the engine/luggage
compartment that show signs of water ingress or signs of corrosion.
VEHICLE REPORT:
Yes, please submit a Vehicle Report if the service solution described in this TJ has no effect or if the
vehicle is outside the structure week, then also add a photo of the cable harness label. Use concern area
“Vehicle Report” and sub concern area “Support not needed”, use function group 3871.
