Engine Identification (ID) Codes

Engine ID codes are issued at beginning of KOER SELF-TEST. Codes are one-digit numbers represented by number of pulses displayed. See Figure. Engine ID code is equal to one-half the number of engine cylinders. For example, 2 pulses would indicate that engine is a 4 cylinder. ID code is used to verify proper PCM is installed and that SELF-TEST has been entered.
