Introduction

Introduction
The A/T system has two self-diagnostic systems.

The first is the emission-related on board diagnostic system OBD-II, performed by the TCM (transmission control module) in combination with the ECM.

The malfunction is indicated by the MIL (malfunction indicator lamp) and is stored as a DTC in the ECM memory but not the TCM memory.

The second is the TCM original self-diagnosis indicated by the O/D OFF indicator lamp. The malfunction is stored in the TCM memory.

The detected items are overlapped with OBD-II self-diagnostic items. For detail, refer to "SELF-DIAGNOSTIC RESULT TEST MODE".
