Greetings everyone,
My Vgate iCar Pro 2S scanner is unable to communicate with any of the modules in my 2005 Mini Cooper S (R53) due to a no-communication problem.
Basically, I've tried everything that's commonly used for this. The splices under the seats appear to be fine, but I saw some strange, non-factory splices under the glovebox that make me dubious. Just wanted to reach out and see if anyone has dealt with a similar dead-bus/no-communications issue and could give me some pointers.
What I've tested—the lengthy version
The scanner connects without a hitch, however neither the ECU nor the ABS will respond.
Specifically, I was looking at the diagnostic bus, which is the violet/white cable. In order to eliminate any potential problems, I unplugged each module on that line individually. This includes the power steering pump (EHPS), which I have verified to be OK.
Concerning the electrics:
The power is flowing into the OBD port.
The integrity of the wire connecting pin 7 to the ECU ensures proper continuity.
Since there is no continuity between pin 7 and the ABS connector, I will have to address the possibility of a broken bus branch leading to the ABS.
No signs of corrosion or pins that have been bent or pushed back are seen on the ABS connector.
To further exclude them, I additionally disconnected a few of more components:
BCM—removed, all connections appear to be in fine working order.
Turned off radio entirely.
And the connections:
Looked under both seats; everything seemed to be in order.
I discovered some strange, non-factory splices behind the glovebox, and they make me suspect.
Please let me know if you have any insights. I am grateful.
