I have a 2002 Acura TLS. Recently the VSA, ABS and warning triangle lights have come on. They are coming on and off randomley with no pattern. The car drives normal. I took it to an Acura dealer and they spent 4 hours troubleshooting the problem. They found a suspect loose ground wire. This cleared the problem for four days but the lights started coming on ... or off again. The error codes are 53-1/16-1/51-1, Abs pump relay short, wheel sensor failure and pump failure. I took the car back and they said it needed a new motorpump at $2,000. Help!! is there something I can do? I don't trust the dealer for reasons I won't go into. I also then took the car to a independent Honda repair shop. They said the sensors were in spec and it was unlikely the pump was bad, in fact they said it was working. Probably an electrical problem. I don't want to dump endless money into this. Does anyone have any suggestions. The light have been on for four days now.

This is my first post. Jim
