happy new years to you all guys!!

i have a problem, no doubt caused by me!!!

the 944 cab has been stuck in a lock up for 9 weeks until today when it went in the garage of my new home, but it had a flat battery. i got the jump leads and connected them BUT even though ithe leads on the porker were red and black, the red was marked - and the black was +, i connected them up the wrong way but only for about 10 secs or so. anyhoos, swopped them the correct way, and she sprang into life on the first turn of the key. other than a flat tyre which i pumped up the tyre with a compressor, runs as sweet as a nut. the prob is the abs warning lamp is on with the central ! exclamation lamp on too. i did notice that the radio isnt working, so could i have blown a fuse, and is the radio circut connected to the abs/warning lamp circut or is there more sinister things going on?

i do hope i havnt caused any damage by my dickheadedness.

regards, a shameful Al.

Take the fuse box (in the engine compartment) lid off and the circuits the fuses protect are listed on the inside of it.

Disconnect the battery & leave for 5 mins or so then reconnect. This will reset all the ECUs. Then see what lights you have on? Then check fuses, I'm afraid you may have fried the ABS ECU so either talk to BBA Reman or see if you can find another at a breaker.

Hi,
This sounds very similar to my car's situation. I know it was in storage for a long time before I got it. Does your car start initially without the warning only for the light to come on after about 10 seconds (and before moving off)? If so thats what mine is doing. I will try the suggestions made above but let us know how you get on resolving this and I will do the same.
Happy new year to you all!

cheers for the replies.

i do hope its just something that can be reset, but just incase, how much is an abs ecu from a breakers?

the warning lamp is on as soon as i turn the key. tbh, the battery needs replacing as its not holding its charge, so thats the first thing to change. i did test the brakes last night under heavy breaking to see if the abs was working and it seems A1.
