First step - check the brake master cylinder fluid level and refill as necessary. Next, check the ABS sensors at each wheel position - clean using aerosol brake cleaner. Be sure to check the ABS sensor wires for rubbing or chaffed insulation.

Then, if still an issue - have the ABS system fault codes scanned / retrieved by any local auto parts store or auto brake repair shop.

Post a reply with the fault code(s) for further assistance.
