Diagnosis (Self-Diagnosis) Function; Code Display/Differentiation Method - Suzuki F6A Service Manual

DIAGNOSIS (SELF–DIAGNOSIS) FUNCTION
The ECM is provided with a self–diagnosis function, whereby it illuminates the check engine lamp in the combination
meter when there is an abnormality in an input signal, providing notification of the occurrence of an abnormal condition.
Further, when control is performed based on this abnormal signal, there is a possibility that engine trouble may occur
and driving may not be possible, so the failsafe function is provided which secures minimal driving performance using a
standard signal in the ECM, ignoring this signal.
