Customer Question

I am in search of info regarding 2 error codes on a 2011 Tahoe (P069E, P0186). However, i am not sure if this is a symptom or cause of the system rebooting (almost seems like there is a short). AC idles down, alternator gauge dips, Navigation system/radio reboots. But engine never dies.

It seems like there is a ton of technical bulletins on system shorts. But not sure where to start with the errors i am currently gettings.

Hi there, I am CAm. Sorry for the delay in getting to your question. Those 2 codes, do they ever reset? Also can I get your VIN?

Customer: replied 1 year ago.
They did not reset until i used my ODM reader and i reset them by accident. but the system reboot systems are still occurring (still not fully sure if this is related or not). VIN is: 1GNSKBE01BR227517

Can You check the code P0186, that does not match in the GM manual.

Customer: replied 1 year ago.
P0186 and P069E was definitely the codes shown by ODM reader.
Expert:  GM Tech (Cam) replied 1 year ago.

Is there a possibility its was a P018C? IF not then it may be a false code and is a result of a bad fuel pump module.

codes have not reappeared since reset but restarts and shorts still occurring.
Expert:  GM Tech (Cam) replied 1 year ago.
OK, let's check the condition of the terminals on the connector going to the fuel pump control module and if you are unable to find any issue, but I believe the fuel pump module will need to be replaced.
