2005 1.6 Focus auto estate problems

[johkaz]

Hi,

I am wondering if anyone would have any ideas about what is causing these problems?

• A week ago, during the heavy rain going to work, I got an Engine Systems Fault come up on my dashboard.
• I stopped the car, switched off and after about 2 minutes I switched on again and the fault was gone.
•  

No other faults with the car until today.

 

• Whilst driving, most of the dashboard display warning lights came on, and again for a moment I got the Engine Systems Fault come up.
• I stopped at some traffic lights, and the Engine Systems Fault warning went off.
• I then still had most of the lights on still, and I got a Transmission Malfunction warning come up, and I lost the main display for the auto gearbox.
• I could change gear whilst stationary, but the warning was still there.
• I switched the car off, and on again to move to a safe place, I lost the warning lights, the auto display came back.
• But I then had a red light next to the Acceleration Reduced warning.

I managed to limp the car home, switched off and then back on again a minute later, and everything was back to normal again.

Hi,

I have had a reply back from the garage about this problem, and they say they have found some error codes.

I don't know which one's yet until i pick up the car, but one thing that was mentioned was about no comms with the dashpod?

Hi,

I got the car back and they found the following codes:

U0155 Lost communication with instrument panel cluster
U0001 High speed CAN communication bus
U0101 Lost communication with TCM
P1260 Theft detected, vehicle immobilized

I have to take the car back if i get any more problems, as they suspect the instrument cluster may be breaking down.

2005 Focus with those codes & faults, it is more than a suspicion, pretty much a dead cert.

Instrument Clusters can often be repaired for about £100, I am handy with a soldering iron, and fixed mine for nothing. A garage will probably set you back about £800 for a new IC. Usually it is just a bad connection where the connector joins the pcb. A break in the HS CAN bus line.
