1994 check engine light. (1 Viewer)

The OD light flashing indicates a fault code with the transmission. Check the FSM as there is a procedure for retrieving the error code similar to code retrieval on the engine.

Thanks for the info! I found the codes and it looks like the transmission is normal. Still have to look more into the CEL.

Correct.

To clarify: You will need a paper clip or piece of wire to stick down in to E1 and TE1 with the vehicle off. Then turn the ignition to on but don’t try to start it. Then count the number of flashes. It will repeat indefinitely on a loop. E1 and T1 are labeled on the cover for the diagnostic Port. It is a small 1”x2” box on the firewall. It says DIAGNOSTIC on it. Flip it open to the right or left (can’t remember).

For instance: two flashes then a longer pause then six flashes is a code 26. It will then repeat OR give you another code if there is more than one.

Report back what you find.

On my 94 80series jm jumpjng out the 2 terminals and it’s not flashing my codes sequence

Does the check engine light come on when the key is turned to "ON"? If it does, you need to check your connections to the terminals in the DLC1 connector. Sometimes it's hard to make the connection in there.
