All dash functions stop, and warnings pop up

[Rs31markie]

Hi all, Just wondered if anyone had any idea what’s up with my car. The other day p/steering failure came up and all the dash lights came on, I stopped turned it off and all good after restart, today same thing except this time it wouldn’t start, engine wouldn’t crank over. I’ve searched the forum and most faults like this point to a battery fault??!!! Thanks for any help

It’s not the battery, just borrowed the battery from my wife’s old car, which is fine and it has the same fault when fitted onto my car.

could be earth connection needs cleaning where the battery lead connects to body. Hopefully its not the Computer playing up. They are very sensitive to low voltage

Something happened once to my wife's Focus. In that incident, the culprit ended up being alternator failure.

What model focus do you have. Have seen LW/LW2 Powershift auto have issues with the TCM that cause symptoms as you describe.

Thanks for replies. Car is a LT manual petrol ‘07. As well as the steering failure it also says ‘speed limiter mode’ Ive recently fitted a new clutch/flywheel I will double check all the wiring connections.

Cleaned up all earth points, and checked all multi plugs. No fault found. It seems that it’s more likely to happen when it’s warm in the car, so I’m thinking perhaps a dry joint or something? Any help welcome

Try to whack on the top of the dash and see if it fixes the problem I read before that the computer on the dash could be the problem.

Hi, tried the whack the dash it didn’t work. Taken all fuse boxes out and checked all connections all ok, took dash out and did same on that. As said before strange as it sounds first thing in morning car will start, if left outside in the sun by the afternoon it won’t start.
But just been told this morning I’m flying to work on Tuesday and staying there!! So guess the car will have to wait 🤷*♂️

Just thought I’d give you an update on my car, as hopefully it maybe of some use to someone else. I do FIFO and got stuck at work for 3 months. Anyway came home car wouldn’t start, battery flat took it off and charged it up, car started once, whilst it was running noticed very bad vacuum leak around manifold area, PCV hose split, decided to take starter off and do it that way instead of taking inlet manifold off. Whilst removing starter solenoid wire it was so tight it pulled the terminal out the solenoid. Fits new hose and new starter, still no start.
Was convinced it wasn’t a battery fault, anyway after a bit of browsing on the internet I find a fairly often reported fault which is exactly my problem. Cracked solder joint into dash circuit board. Remove dash and with the aid of a magnifying glass you can actually see the joint has cracked on several connections. After cleaning and re soldering 3 joints dash is back in and car appears to be fine. Several videos of this problem are on YouTube just type in ‘mk2 focus dash repair’ . Sorry for long winded update, hopefully this may help someone out, I believe a ford dealer charges $700+ for this repair.
