I suddenly have multiple "malfunction" lites (ABS, PCS, Traction, Cruise) BUT no known problems or symptoms other than an ABS OBD code. The forums here point at many different possibilities from washing the car to checking all sensor connections...etc. HOWEVER -- could it be that an ABS wheel sensor would cause all 4 "malfunctions"??? I mean, I can see how the ABS is ties to all 4 of those systems yeah? Please advise.
