ON-BOARD DIAGNOSTIC SYSTEM FAIL-SAFE FUNCTION [PCM (FN4A-EL)]


id0502q2280200


Function

•  In the fail-safe function, minimum vehicle drivability is obtained by changing the signals that are determined to be malfunctions by the malfunction detection function to the preset values, and limiting PCM control.
