Transmission Control Systems

If a trouble code is displayed during the diagnostic trouble code check, check the circuit listed for that code in the table below.






*1 "O" mark means O/D OFF light blinks once every 2 seconds.
"X" mark means O/D OFF light never blinks.
*2 "O" marks means the ECM memorizes the malfunction code in the ECM

HINTS:
^ If the malfunction returns to normal while a malfunction warning is being output. the O/D OFF indicator light stops blinking and goes off.
^ However. the trouble code is retained in memory until it is cleared from memory.
^ If the diagnosis system outputs a diagnostic trouble code even though the O/D OFF indicator was not blinking, there is intermittent trouble.
^ Check all the connections in the circuits corresponding to that code.
^ Codes 42, 62, 63 and 64 are limited to short or open circuits in the electrical system which consists of the solenoids, wire harnesses, and connectors.
^ The ECM is unable to detect mechanical trouble (sticking valve. for example) in the shift solenoid valves.
