Hi. While trying to diagnose the traction control & skid warning lights on - with information from here, the truck (2012 Navara D40 V6) is showing only the P0606 fault code.
Has anyone had this code and been able to fix it?

A web search says it's an internal ECU error. The truck is running ok.

I had the ECU programmed to remove the ERG fault when the valve failed a few years ago and I blanked it off.

I'm not sure if it's related to the warning lights, but I don't think so. I've not had a chance to work through the possible causes of the warning lights on.

I'm showing as a newbie here as I had to re-register. I've contributed for several years and also I've benefitted massively from the knowledge shared by members.
 
The manual says it's an "ECM calculation function is malfunctioning". Diagnostic procedure is as follows:

1) Turn ignition OFF and wait at least 10 seconds
2) Turn ignition ON and wait at least 5 seconds then check DTC, if it is clear the code and perform steps 1 and 2 again. If the code persists, replace the ECM.

That's the manual.

I'd check the earth on the ECM. It's a known sore point.

Thanks Tony, I'll check the earth then do the sequence you said.
I found on linkedin (Google search took me there) someone had P0606 caused by a short filament brake light. Unfortunately for them they found it after swapping the ECM and the new one registering the same error.

Thanks again for your advice.

Hi Tony. The issue is fixed and the fault code has gone.
Thanks for your time and help.
