Hi to everybody, I need some help please. My ignition barrel broke and the "mechanic" as changed the barrel the cluster the bcm the ECU and the gateway modules but the abs lights flash. The car drives as it should but I am unsure how to sort the abs problem. I do have the original modules but fear the mechanic as made a major problem as he did not change the abs module at the same time. Any help would be greatly appreciated. Thanks for any advice.

I would be tempted to read any fault codes to find the exact cause of the error and resulting light showing

It could be non-related and worth checking to see if it is a coding issue which may be possible to code into the vehicle using the correct equipment
