Error code p0605

[drparkerycms]

I just put a new battery in my L 4701 and when I tried to crank it, it would turn over but not start. Error code p0605 came up. Does anyone know what this means and can I clear it or do I need to call a repair tech?

My first thought, check your connections to the battery and make sure they are good.

Hello & L4760- Got starting issues

Fireman, I'd ask the dealer where you have your tractor what the cost is to have him program the ECU if you have your serviced. Don't need to tell him you're purchasing a different one, you just need to know if he's willing to program a ECU for your tractor. With his answer either purchase the...

Also, here is a forum post on someone else dealing with that error code.

For anyone that looks at this post, this is what is in the Workshop Manual for the L3301, L390 and the L4701:

P0605 ECU FLASH ROM and CPU abnormality

When the code P0605 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is failing its Read Only Memory (ROM) self-check and has found errors within its Read Only Memory functions. In many cases, the PCM is not getting a high quality, consistent 12 volt power and ground signal.

Now the BIG question is, are ALL OBD-II code the SAME or do different manufactures use 'their' numbers for 'their' errors ?

DTC format and general organization is standardized. The SAE and EPA have standardized specific codes which are mandated in the US by law and/or regulation. Some of the undefined code space has been reserved for use. The remainder of the code space is more or less undefined and left for OEM specific use. SAE J2012 is the governing standard in the US.

Is it possible that you just need to clear the error code? The WSM has that procedure and also how to check/set your model in the ECU.

Kubota does not follow all the standard codes, Read and go by what the WSM says the code is.

Thanks for all your help. Had a service tech out this morning, and after he cleaned the sight glass in the fuel line we spent an hour looking for the plug in for his diagnostic tool. ( it’s under the cowl and was a bitch to get to. 2015 model) never could get the ecu to talk to the computer so now I’m waiting on them to come pick it up and take to the shop. Wish me luck
