To the OP: You're entitled to your opinion, however, the anti skid and traction control lights come on along with the CEL because they feel that those systems can't adequately do their jobs while there is another fault occurring in the engine management system. Furthermore, Toyota is the most reputable manufacturer there is. When they find a problem with their vehicles they recall and fix them when others would just say it's not their fault. They've done several recalls on engines sludging up when in fact if the owners had done proper maintenance it never would have happened. They had a recall on the dashes of some models because they become sticky after time. Toyota has built their reputation as the most reliable vehicle manufacturer and they aren't about to scam anybody just so their dealerships can make a few extra bucks. Dealership service departments are a part of independently owned dealerships. Other than selling a few parts, having people bring their cars in for malfunction lights does nothing for Toyota Corporate. You think they would risk their reputation to help their dealer owners?
