Self-Diagnostic System: Introduction

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2002 Toyota RAV4, 2002 Toyota Highlander, 2002 Toyota Camry, 2002 Lexus RX 300, and 2001 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Before testing transaxle, ensure fluid level is correct and shift cables are properly adjusted. Ensure engine starts with selector lever in Park and Neutral to ensure proper adjustment of PNP switch. Transaxle must first be tested by checking for stored DTCs. See RETRIEVING DIAGNOSTIC TROUBLE CODES .

ECM monitors transaxle operation and contains a self-diagnostic system which stores DTCs if transaxle electronic control system failure or problem exists. Malfunction Indicator Light (MIL) on instrument panel will illuminate to warn driver a malfunction has occurred.
