I have several. Just figured out my stop lamp switch is the likely cause. Cruise control stopped working and traction control light stays on. Must be some weird Nissan way of telling me something's wrong?
Tested and brake lights didn't function. Yeet. Been ignoring that shit for a hot minute. 😬
Plan to replace both pedal switches as a start.
If you're curious, C1116, P1805, U1000, U1001
I'm not sure if these are even all related, but replacing the switch and checking all fuses/relays is the cheapest and easiest place to start from what I can tell
Give me 1 sec
If your cruise control stopped working, that's your cruise control relay or your speed sensor.
Brake lights, you probably just need the light bulb.
I doubt both went out at the same time. And both stop brake lights at that.
The cruise control turns on, it just won't let you set a speed.
Unless they both pass through one circuit?
But from my research, the Frontier can lose brake lights, throw ABS codes, disable cruise control, and show a traction light with a faulty stoplamp switch. All of which I have going on. Seems reasonable to start there.
Your cruise control is fine. It's that your car's computer is out of whack because of the brake switch
Yeah that's what I was thinking. It actually kind of makes sense if they did that on purpose. That combo of problems is probably easier to diagnose than any one code. That's a guess anyway. Could just be accidental on their part.
Apparently some cars won't even start or shift out of park. So I guess I got off easy, if not dangerously.
By the way, I appreciate you reaching out. It's helpful to bounce ideas for this shit. Especially on newer cars.
P1805 says its the break switch. Tgis communicates with the cars ecm. The other codes is saying your cars computer is out of wak because of code p1805
I think there is some time delayed communication between the switch and the computer too, which is probably the communication error. It sees me driving but never hitting the breaks I'm guessing 😂
Tgis is what you need. The break switch that is right next to the cruise control sensor
