On 19 June 2013 I applied the brakes on a damp/wet road. Before coming to a complete stop I experienced a sort of hopping of the front end while going over a rough section of roadway. This sensation has occurred numerous times before and I was told it had something to do with the anti-locking brake system but nothing specific.
Abs system malfunction. Code c0265. Internet research indicates that this model year (2000) and other similar models and surrounding years have this failure. Grounding failure to abs computer module resulting in the necessity to replace module.
