OBD Code Reader

[JerryK]

Thanks for the quick reply. I was actually quite surprised to read that diesel powertrains work with the OBDII standard. I have a diesel-pusher motor coach, and it uses a round (9-pin?) diagnostic port that won't work interface with the OBDII standard plug. ScanGauge actually makes a diesel version of their hardware for those rigs. So I never gave it any thought to attach my bluetooth scanner to the tractor until I came across this thread.

I've made a cursory scan of cables inside the cab of the 2555, but didn't find anything. A search on YouTube shows one guy (in an open Mahindra tractor) pulling the port from a bundle that is more under the hood than at the operator area.

I'll give it another look with daylight. Thanks again...

Open up the hood. OBDII port is dead center above the battery/air cleaner facing forward. Has a black cover on it and is a little hard to see if the hood is blocking your barn lights, and if you have 'old eyes'....... [ sniff, sniff-sniff ] [ in the below picture it is at the very top center... ]

That is priceless info. Thank you! Unfortunately the daylight disappeared before I returned home today. And, my barn isn't built yet (though materials are all here). This time next week I won't have that excuse! I'll post back tomorrow, if the process isn't overcome by other events.

@jerryk - that was it! Right where you said it'd be. Now I have to find my BT OBDII thingy I bought over a year ago...

At least you are young enough that you can remember you have one and not order another........ hard enough to find one you already bought...

That's funny, and so true. 1/2 the battle is remembering you already have one. The other half is remembering where you put it. I scored 100% on both this time... But I had plenty of practice. This BT adapter is probably the 4th one I've ordered over the last few years due to failing one (or both) of the points above. With plenty of repetition, an old dog can sometimes learn new tricks.

The MIL light on my 2555 comes on every once in a while (always related to low RPM operation). I wanted to see exactly what code(s) were being generated, so I bought this:

Amazon.com: GXG-1987 WiFi Wireless OBD-II Mini ELM327 OBD2 Auto Car Diagnostic Scanner Tool Adapter Reader Scan Code Tester for iPhone 6S 5 iPad4 iPod mini IOS PC Windows, Android Device …: Automotive

I also bought "Torque Engine Management Diagnostics and Tools" for my Android ($5.00 from Google Play Store). I've only had to use it once, but it worked flawlessly. It was able to retrieve and clear the two codes it found (EGR-related, of course). I was also surprised that it recognized my tractor as a Mahindra 2555 and displayed several of her mechanical properties as well (engine displacement, Weight, etc.). This software can do a whole lot more than retrieve codes, but I didn't have any extra time to spare. But I'm sure I'll find time to explore its capabilities soon enough.

For only a $20 total investment, I'm able to see exactly what's going on with my engine.

Man, I wish it was that easy with my 1969 Cutlass.

Where can I find these?

Where can I find these? No show on Amazon.

You need to also know what kind of plug it has. My Actron came with 5 cords for OBDII equiped vehicle and an OBDI plug.

You can use the 2021 new crp129x scan tool which is the updated version of the previously mentioned CRP129.

One of the popular features of LUNCH CRP129X that make this diagnostic tool stand out, and above the rest is the book button.
