Trouble Code Retrieval

A while back someone was looking to retrieve trouble codes without going to the dealer. While investigating something on a Progator 2020, I ran across the following in the operator's manual. It would be a long shot this works on other gators, but I'll throw it out there anyway in the event it helps someone.

Perhaps if the technical manual for the progator was referenced for the pin identification and such, the same analogy could be used on the other gators.

Here's a link to the manual: OMTCU38792


Using Diagnostic Plug to Retrieve Diagnostic Trouble Codes

1. Raise attachment to service position. (See Using the Lift Cylinder Safety Support in the Safety section.)
2. Park vehicle safely. (See Parking Safely in the Safety section.)
3. 
   
   TCAL45106-UN-14MAY13
   Locate diagnostic port (A) near right rear of tire.
4. Remove port cap and insert diagnostic plug supplied with ProGator.
5. Turn the ignition key to the run position
6. The system will now enter the self diagnostic blink code mode. Be ready with pen and paper to write down any codes that may be stored.
7. The ECM will flash the MIL indicator with a pause between represented numbers that represent DTC codes. The sequence starts with code 1654. Code 1654 confirms the system has entered the blink code mode. The ECM will flash code 1654 (3) times before displaying the actual DTC code that may be set.

Example:
One short blink (pause) six short blinks (pause) five short blinks (pause) four short blinks.
If no DTC codes are found, the ECM will continue to flash 1654 only. This means no stored DTC codes were found.
If one of the numbers in the DTC code is zero (0), no flash will occur to represent the zero value–it will be represented as a short pause.
