Diagnosis & Repair

NOTE: Read freeze frame data using OBD II scan tool or hand-held tester. Because freeze frame records the engine conditions when the malfunction is detected. When trouble shooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.

For wiring diagram and diagnostic procedure, see appropriate DIAGNOSIS article in AUTOMATIC TRANSMISSIONS.
