I have some problems from times to times with my ABS module (not always, it happens only when I do not use the car for several weeks, and only during the first 10 or 20 minutes). When I am breaking, the car is going more or less slightly to the left direction. The reference of the module is GM 15220711.
I gave it to the garage, and they found that the ABS module is defective. It is not an electronic issue, there is no message on the dashboard. But the mechanical part (the piston or valve for the right forward brake) is blocking sometimes, mainly when it was not used for a long time.
Can you fix this issue ?
No, we don't fix that type of issue. But you can, have your brake system flushed then have an ABS bleed performed on it. Whit the fresh fluid and then an ABS bleed this should really help your issue
thank you very much for your answer, we will try
