CODE 41 - CYLINDER SELECT ERROR

Due to the same ECM being used for different engines, it is necessary for the engine application to be selected. This is done by leaving terminals "B12" and "D-3" open for six cylinder applications. Code 41 will set if the reference pulses are not equal to a value selected within the PROM when engine RPM is below 2000.
