Automatic Transmission System

If a malfunction code is displayed during the diagnostic trouble code check, check the circuit listed for that code in the above image and proceed to the appropriate section.

*1: "O" mark means O/D OFF light blinks once every 2 seconds.
"X" mark means O/D OFF light never blinks.
*2: O" mark means the ECM memorizes the malfunction code if the ECM detects the diag. trouble code detection condition.





*3: This indicates items for which 2 trip detection logic" is used. With this logic. when a logic malfunction is first detected. the malfunction is temporarily stored in the ECM memory. If the same case is detected again during the second drive test, this second detection causes the O/D OFF light to blink.
The 2 trip repeats the same mode twice. (However. the IG switch must be turned OFF between the 1st trip and 2nd trip.)

HINT:
- 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 malfunction code is retained in memory until it is cleared from memory.
- If the diagnosis system outputs a malfunction 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.
- If the vehicle speed sensors No.1 and No.2 happen to fail simultaneously, the ECM will neither alert the driver by blinking the O/D OFF indicator nor record any diagnostic trouble code. It will, however. decide that the vehicle can be driven only in 1st and none of the other gears, shifting upward will then be prohibited.
- Codes 46. 62, 63 and 64 are limited to short or open circuits in the electrical system comprised of the solenoids, wire harnesses and connectors. The ECM is unable to detect mechanical trouble (sticking, for example) in the solenoid valves.
