BO TIE 1

When I had my 2014 Silverado I had a few lights out. They had to replace the whole unit.

Possible the previous owner had a tune on the truck. Might be tuned out.

Try disconnecting the range and see if that's the problem.

I've seen battery cables that look perfect on the outside and the inside was corroded. Hey good luck. Hope you get it figured out.

I would check the battery cables then. Have someone turn the key while you move the cables around.

Did you do a voltage test on the battery? You can go to most auto parts stores and have it tested for free.

I had a problem with my 2018 Silverado LTZ last year. The right rear tail light would light but no signal or brake light. Unfortunately the whole assembly has to be replaced with the led lights. Luckily I was still under warranty at that time. Hope this helps, good luck.

Sorry yeah it's two beeps after the beep on the right rear. Do all the tire pressures show in the DIC when you are driving after your done and then just go blank?

Did you start at the driver's front wheel and work around to passenger side and finish with the driver rear? You have to wait for the truck to Beep once at each tire, when done the truck should beep three times completing the process.

Have you gotten a check engine light?

No just used a thin blade to clean the groves.

I've had something similar happen to me. Turns out I had a buildup of lint in the groves of the key. Cleaned it out and all good. Sounds crazy but it worked.

I`ve been having this problem since Monday. I emailed Tapatalk to let them know. No response from them. Not sure where the problem lies.

Get a handheld tuner. I know Diablo has tunes for the six speed. I have one on mine and it shifts great. If your not comfortable doing it yourself take it to someone that can tune it for you. Sent from my SM-N975U using Tapatalk

Check the screws behind the the panel under the steering wheel. Remove the panel and there's 4 screws behind there. They are usually loose. That's where I would start. Hope that helps. Sent from my SM-N975U using Tapatalk
