Hi All, I have put the C4 Picasso in for a recall - (the plastic behind the battery) whilst in i asked for a diagnostic because i have been getting the random errors on antipollution, handbrake and traction control, i was thinking it was the fusebox problem so told them and they knew the errors to look for to say it was a defo fusebox failure. Anyway they called this afternoon saying the fusebox isn't the problem and it's actually a problem in the loom and to fix it would take another couple of hours to go through the loom testing all the wiring etc. I got a copy of the fault log and it shows the following: U1209 - Gearbox - Fault in the information transmitted by the engine ECU, incorrect value received distant U1208 - ABS / Traction - Fault: no communication with engine ecu. Data invalid distant FC82 - ECU at the top of the steering column - Fault in communication with the transponder. not charaterised. local. FB88 - Instrument panel - All or nothing input button no1 jammed. not charaterised. local. FB8A - Instrument panel - All or nothing input button no3 jammed. not charaterised. local. That's all i got, alot of them are repeated and the log shows 400 events but that is just one page. Anyone got any ideas, seen this before? not really sure what to do now with it.... EDIT: This is a 2.0 Petrol EGS. |

If you go to this page on site: - Click Here - You can input the error codes and download the associated 'information' documents which will tell you were the problems may lay. U1208 says to look at the connectors, Can Bus and ABS Control unit U1209 says to look at the connectors, gearbox ECU and ESP ECU FC82 does relate to the steering wheel control but states: Only take account of this fault if it appears during a keys initialisation phase or during a failure of the vehicle to start. This fault code does not need to be dealt with just for a difficult start It does seem that there are some dirty connections somewhere on the car. Previous threads would lead me to check the Gearbox Actuator wiring first. |

Cheers Dave, I have downloaded them documents after i posted i realised i could get them!... So just needing to go through all the connectors and unplug and clean them? don't sound to bad, if it's dry today i'll do it. Is there a place where the engine ecu loom plugs in somewhere else, always seems to be a common fault is that the engine ecu is not communicating on the CAN bus, I have seen another error saying about a mute engine ecu, think that was the BSI complaining. I'll have to get my lexia on it to do a full read i think... |

Chances are it'll be corroded / broken wiring behind the battery in the main loom.
