Codes popped up any help

[Stonefishranch]

I have a new l 4701 Kabota I had three codes popped up yesterday PO 629 PO 627and a PO 606 still can't get the dealer to tell me anything anybody have any suggestions or may know with these codes are thanks for your help

Just Google the code: Those should be zero's not O's and there should be no space.

P0629 means there is an issue with the "A" control circuit in the fuel pump often due too bad connectors/wires or a defective CAN bus

P0627 - Fuel Pump 'A' Control Circuit/Open

Possible causes

- Faulty Fuel Pump
- Fuel pump harness is open or shorted
- Fuel pump circuit poor electrical connection
- Faulty Fuel Pump Relay
- Faulty fuel pump control module (if applicable)

P0606 OBD-II Trouble Code: PCM Processor Fault

What the P0606 code means

The Powertrain Control Module is sometimes referred to as the Power Control Module, or the Engine Control Module (ECM); all of these names mean the same thing. The PCM is responsible for monitoring every aspect of the vehicle’s engine and electrical system.

When the vehicle is started up, the PCM will perform a self-check to make sure that all of the engine’s components are operating properly. If the result of this self-check indicates that there is a processor fault in the the PCM, it will store the P0606 diagnostic trouble code.

What causes the P0606 code?
•PCM wires that are broken, corroded, and/or frayed
•PCM connectors that are broken, corroded, and/or frayed
•Faulty PCM ground circuits and/or output devices
•Faulty Controller Area Network (CAN) bus communication

Bucktail,
Are you basing this on actual knowledge that, that is indeed what the codes mean or are you just basing this off of the codes of OBDII off the internet?

Several Kubota techs have said that Kubota codes are not the same as OBDII codes.

Just basing this off of the codes of OBDII off the internet. The search listed the codes as all being general codes, so I figured that they should apply, but they could be different for Kubota.

Thanks!
I'm not saying your wrong, because I too do not know.
I would like to get a solid answer so that everyone will know for sure!

Sorry, can't help you there.

According to the e mail I recd form Kubota, they use the std OBDII codes plus "manufacture specific codes." All manufacturers do this, to include Dodge, GM, and Ford.

After a
Having to charge my battery to start tractor, the code P0606 came up. Should I reset it?

 

[mdhughes]

This is from the Workshop Manual for L3301, L3901 and L4701:

P0629 - SCV (MPROP) drive system abnormality
P0606 - ECU FLASH ROM and CPU abnormality
P0627 - Not in the manual

Yes, clear the code, start the tractor and see if it comes back. If your battery was low and your having to charge it, chances are its not coming back.

Whitetiger,
Without a diagnostic tool, is there a way to clear the flashing code?
Thanks,
Tom

Newbie check back to your thread, I added another link with a method you can try at home if white tiger doesnt check in.

you can sometimes clear them from the panel but they won't clear from the ecu

some codes that are stored in the ecu will generate a code in the panel even after you clear the panel

diagmaster is the only way to access the ecu, proprietary to kubota. Dealer only. Sorry for the bad news but it is what is is.

Be careful about "googling" P codes. Kubota's nomenclature is different than everyone elses including automotive industry. They might mean the same thing but Kubota's terminology is different which might make you chase your tail

finally for a solution since 2 are somewhat related look closely at the wiring on the top of the engine, near the valve cover. I've seen rats build nests beside the valve cover and they apparently sleep while munching on wires or something. Normally I can smell their pee BUT I've had covid recently and still ain't regained my smeller or taster. GF cooked dinner the other night and we ate good but it was something that I don't normally eat, cheesy and I am not a fan of most cheesy foods! Couldn't taste or smell it.
