Code To Circuit/Pinpoint Test Menu

NOTE: In addition to transmission fault codes, engine-related fault codes may be output during QUICK TEST  procedure. These fault codes pertain to engine performance and must be repaired first as engine performance will greatly affect transmission operation. For information and testing procedures of engine-related fault codes and components, see TESTS W/CODES - EEC-IV (2.0L) article in ENGINE PERFORMANCE.
NOTE: No trouble code was available from manufacturer for 3-2T/CCS component malfunction. If component is suspected, see PINPOINT TEST G  .
