Displaying & Reading Trouble Codes

HOW TO READ DIAGNOSTIC CODE (A140E)





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

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





2. SHORT TERMINAL ELECTRONIC CONTROLLED TRANSAXLE (ECT) CIRCUIT.
Using a service wire, short the service connector terminals ECT and E1 of the service connector.






3. READING 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 for 0.25 seconds every 0.50 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 a 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.

Diagnostic Codes:

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 service connector terminals ECT and E1.

NOTE: If codes 62, 63, 64 appear, there is an electrical malfunction in the solenoid.

Causes due to mechanical failure, such as a stuck switch, will not appear.
