IrvesBMW Posted March 14 Share Posted March 14 Issue - The parking sensors are non-functional and a manual intervention warning is shown on the screen. This particular variant has the PDC module integrated into the "Junction Box Electronics" module, which is located next to the fusebox. The actions I have taken. Verified with ISTA. The statement asserts that all the sensors are defective, which is improbable. To the best of my knowledge, the sensors consist of three wires - a 12-volt wire, a ground wire, and a sense wire. I have verified the presence of electrical power at the JBE connection when the PDC is in the "on" position. There is no information or content. Both the 12V and ground connections register as ground when tested with a power probe. Additionally, I have verified this by disconnecting the sensor's connector, in case there is a possible hard short. There is no 12V power available. I am unable to locate a specific fuse for the PDC, and ISTA (unfortunately) states that the PDC circuit receives power from the JBE. All the fuses for the JBE are in fine condition. In my opinion, it seems to resemble a defective JBE. Given the substantial amount of money involved, I would want to inquire if anybody have any prior experience, innovative ideas, or insightful views before I forward with the action.

Matt865 Posted March 14 Share Posted March 14 If the jbe detects malfunctioning sensors, it will off the power. Assess the continuity between the jbe and sensors, and inspect for short circuits by disconnecting both ends. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted March 14 Author Share Posted March 14 Understood - it seems like a well-thought-out strategy. I will provide a report once my return. Quote Link to comment Share on other sites More sharing options...
Matt865 Posted March 14 Share Posted March 14 If you have ISTA, reconnect it and proceed with the test plan before checking the wiring. Quote Link to comment Share on other sites More sharing options...
IrvesBMW Posted March 14 Author Share Posted March 14 Additionally, it is a commendable suggestion... I was unable to complete the task tonight due to a lack of time, but I will resume working on it soon. Quote Link to comment Share on other sites More sharing options...
WordSmith Posted March 14 Share Posted March 14 Were you successful in resolving this? I am experiencing a similar problem. Quote Link to comment Share on other sites More sharing options...
Craigbelont Posted March 14 Share Posted March 14 Once I successfully activate my OBD port, I will then proceed to give information that has a striking resemblance to what you are seeking. 🙂 Quote Link to comment Share on other sites More sharing options...
Craigbelont Posted March 14 Share Posted March 14 May I have a photograph of the defect on the vehicle's display screen, please? Thank you. Quote Link to comment Share on other sites More sharing options...
