ABS and Brake light on on the dash. C0055 is the code. Warning lights are on all the time. Speedometer works fine. Swapped the 2 rear speed sensors from side to side. Read elsewhere that 4WD warning comes on instead. Ohmed out both speed sensors and 1.3K ohms. Could it be the ignition switch or the EBCM??
