Read Diagnostic Code
(Without Super Monitor Display)




1. TURN IGNITION SWITCH AND OD SWITCH TO ON
Do not start the engine.

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




2. SHORT ECT TERMINAL CIRCUIT OF CHECK CONNECTOR
Using a service wire, short terminals ECT and E(1) of the check connector.




3. READ DIAGNOSTIC CODE
Read the diagnostic code as indicated by the number of times the OD "OFF" light flashes.

4. DIAGNOSTIC CODE




a. If the system is operating normally, the light will blink once every 0.25 seconds.




b. 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 second pause, the second number of the two digit diagnostic code. If there are two or more codes, there will be a 2.5 second pause between each.

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

c. Remove the service wire from the check connector.

NOTE:
- If codes 62, 63 or 64 appear, there is an electrical malfunction in the solenoid.
- Causes due to mechanical failure, such as a stuck switch, will not appear.
- If diagnostic code Nos. 42, 61, 62 or 63 are output, the overdrive indicator light will begin to blink immediately to warn the driver. However, an impact or shock may cause the blinking to stop; but the code will still be retained in the ECT computer memory until canceled out.
- There is no warning for diagnostic code No.64.
- In the event of a simultaneous malfunction of both No.1 and No.2 speed sensors, no diagnostic code will appear and the fail-safe system will not function. However, when driving in the D range, the transmission will not up-shift from first gear, regardless of the vehicle speed.
