Citroen C4 Grand Picasso semi automatic U1213 fault

Post by Iverson3 »

Hi guys.

I'm new on this forum however I have the same car like in the past. A Citroen C4 Grand Picasso semi automatic, and I always have electrical problems with it. Unfortunately, it has already had an electronic issue, specifically affecting the left rear parking brakes and the right rear wheel sensor.

I wanted to take it to an auto-electrician before replacing the clutch and a BB1-3366A ball bearing in the gearbox.

My mechanic said it would be fine to go ahead, but problems arose. He replaced the clutch and fixed the gearbox, but it refuses to programming, constantly shutting down before it's finished whether with Autel or Snap-on.

We can't figure out what the problem might be because everything went smoothly with my previous car (which didn't have any electronic issues).

What do you think could be the solution? Should the electronic issue be resolved before attempting programming?

Or could there be an issue with the ECU? There's also an error about the negative battery voltage sensor connected to the battery malfunctioning. Is it possible that because it's not distributing voltage correctly, programming is hindered, as it showed errors on almost every ECU due to this?

It's urgent because I'm a self-employed individual, and without my car, I'm immediately unemployed. :( If anyone could help, I would be extremely grateful, or if you know where to take the car around the Liverpool area (as it can't move on its own anymore).

Thank you very much.

I believe the general advice here is that you'd need to try with a proper Lexia scan tool and Diagbox.

The 3rd party scantools can be good, but they can be buggy at times with certain vehicles.

Hi. Thanks. May I ask who use this tool? Citroen only? Or a proper car electrician also?
Thanks

You also need an external power supply to keep the voltage up. But I think that U1213 is probably stopping it. Is the ABS ECU online?

Yes we put the battery on continuous charge. Voltage was around 14V. It gives lot of fake faults which is cause by the sensor fault or the parking break fault.
