CHECK O/D OFF INDICATOR LIGHT
1. Turn the ignition switch ON.
2. The O/D OFF light will come on when the O/D switch is placed at OFF.
3. When the O/D switch is set to ON, the O/D OFF light should go out.
If the O/D OFF light flashes when the O/D switch is set to ON, the electronic control system is faulty.




HOW TO READ DIAGNOSTIC TROUBLE CODE
1. Turn ignition switch and O/D main switch to ON. Do not start the engine.

HINT: Warning and diagnostic trouble codes can be read only when the overdrive switch is ON. If OFF, the overdrive OFF light will light continuously and will not blink.




2. Using SST 09843-18020, connect short terminals TE1 and E1 of the DLC 1.




3. Read the diagnostic trouble code as indicated by the number of times the O/D OFF indicator flashes.




Diagnostic Trouble Code Indication
- If the system is operating normally, the light will blink once every 0.25 seconds.




- In the event of a malfunction, the light will blink once every 0.5 seconds. The number of blinks will equal the first number and, after 1.5 seconds pause, the second number of the 2 digit diagnostic code. If there are 2 or more codes, there will be a 2.5 seconds pause between each.

HINT: In the event of several trouble codes occurring simultaneously, indication will begin from the smaller value and continue to the larger.

4. Remove SST 09843-18020.




DIAGNOSTIC TROUBLE CODES

HINT: If codes 62, 63 or 64 appear, there is an electrical malfunction in the solenoid. Causes due to mechanical failure, such as a stuck valve, will not appear.
