The error code, U1000, on a 2002 Chevrolet Trailblazer might mean that there is a communication problem with the ECM. ECM stands for Engine Control Module. Sometimes when it rains and the engine gets wet, this light will come on to tell the driver there might be a wire that got wet going to an electronic part. It will also indicate a short of some kind in the wiring so it is best to check all wire connections.
