Help with these codes

Man! Got in the truck and dashboard LIT UP! no idea what these mean/are tried googling and a ton popped up. Anyone on here experience this? Funny thing is I haven’t towed anything with this truck since I got it 8 months ago so I’m confused.

 

I'd bet money it's a slew of "Me too" codes. Basically, one computer throws out a trouble code, and the rest of the various computers on the CAN communication line throw up a code saying "Look at that guy, he's got something wrong." I think the most common cause of all these is a malfunction in the brake controller, which is usually fixed by a reflash. But don't take the brake controller suggestion as gold, there are plenty of other possible causes. My '15 displayed similarly a few months back because of a momentary loss of communication with the gauge cluster. I had codes in the ABS/Trac computer, engine ECM, and various others all saying loss of communication in the gauge cluster. At the end of the day, it'd be best to get it into the shop and get the codes read.

 

Thank you!

 

These are the exact two error messages I had last week on my Tundra. Check your under hood wiring carefully for rodent damage. Rats chewed up the fuel injector wiring harness on the passenger side of the engine. Replaced that and all error messages cleared.

 

Stupid question but would this have anything to do with me switching out the old grill/insert? I’m thinking the collision control maybe?

 

Anything is possible. When did you swap grilles?

 

About 2 weeks ago. TSS sensor and all.

 

I’d start there. Maybe double check the radar connector. I’ve had that issue before as well.

 

Right on. Thank you brother

 

Yeah I was gonna say those codes look like the TSS sensor codes. I’ve seen similar in snow storms when the sensor is blocked, also if something is covering it like a bull bar.

 

Yeah I’ve got the sensor vinyl’d black but it’s worked for weeks now there seems to be a problem?
