NOTE:
Use trouble code charts only if SERVICE ENGINE SOON light is illuminated (indicating a current problem exists). Exceptions are Code 13, 15, 24, 44 and 45 charts, which may be used to help diagnose intermittent codes. Anytime control module-related Codes 51, 52, and 55 are displayed with another code, start with 50-series code, and then proceed to lower numbered codes.
