Omega General Help / Re: ABS light still on after ECU change
« on: 25 April 2013, 23:03:40 »
Thanks for your advice.
Both ECUs were from 2 litre petrol manual Omegas, one a T reg, one a V reg. The V reg was working OK when scrapped. The numbers were not identical, but similar. On fitting each worked normally initially (ABS light on on turning on ignition, then going after 4 seconds, staying off on engine start, staying off on turning car in drive, then on driving out of drive and turning left down the hill light came on. On neither occasion did I see the light come on, but both events were amazingly similar.
How would I obtain an ECU with a more similar part number? Which part of the number is critical? Most of the numbers were the same. Both pump units were DF models.
I have been here before! IN 2007 my 3.2 ex police Omega behaved similarly. I bought a used ECU for a V6 manual from Steve Brown for £200, fitted it, and the fault remained. I took Steve's ECU off, sent it back for refund. and sent my ECU to ecutesting for repair. They said it was all right, sent it back, charged me a fee. I then replaced my old ECU, concluding fault lay elsewhere.
Swopped all the wheel sensors, no change. Then I checked the cogged wheels. The rear o/s cogged wheel was loose on the half shaft end and was sliding in and out of line with the sensor. I glued it in place with Araldite. Fault cured.
