Diagnosis system
1. CHECK DLC3
The ECU uses ISO 15765-4 for communication.
The terminal arrangement of the DLC3 complies
with SAE J1962 and meets the ISO 15765-4 format.

ECM / PCM Processor
DESCRIPTION
The ECM continuously monitors its internal processors (CPUs), A/F sensor
transistors and heated oxygen
sensor (HO2S) transistors. This self-check ensures that the ECM is functioning
properly. These are
diagnosed by internal "mirroring" of the main and sub CPUs to det ...
