The codes for Pre-1995 Dodge Trucks are retrieved from the ECM, by counting the check engine light flashes.
1.) Turn key on, off, on, off, on......and wait
Then the light will flash for example
On/off/on/OFF......On/off/on/off/on/OFF.............................
This will be a 23 code...
Then it will move on to the next code, until it flashes on a 55 code
on/off/on/off/on/off/on/off/on/off....on/off/on/off/on/off/on/off/on/OFF...........
This will be the 55 code or end of message
So it will read like so
On/off/on/OFF......On/off/on/off/on/OFF............................................
on/off/on/off/on/off/on/off/on/off....on/off/on/off/on/off/on/off/on/OFF...........
.
