2019 Nissan Sentra 1.9L, has a C1A12 code, Emergency Braking. It's the sudden braking system. Dealer charges over $1200 dollars to fix it. It needs to be adjusted. I tried to adjust it myself, but to no success. Is there anyway a DIY way to repair or otherwise, delete the EAB system totally?
Was th car in an accident or was the distance sensor replaced?
I believe this is the code for it not being aimed straight? Usually this one is there because of an accident or something being bent. A lot of times you need to replace the bracket for the sensor and align it, which requires a scan tool that can do the laser/radar milliwave adjustment. You'll also need a target board of some sort and a way to verify the board is straight. We have a laser that attaches to an alignment head on a wheel.
I'm not sure that this adjustment is possible without the equipment. The code doesn't clear for this unless you adjust it properly, and a level isn't good enough because there are three different angles the target has to be changed to during the scantool operation. It has to be accurately done for the code to clear, like less than 1°. Even 3° out of spec calls for replacing the sensor and bracket, assuming damage.
I'm not familiar with a way to disable that system completely because it's part of the can network and is standard on all of them, so it can't just be configured out. You might have an option in the cluster menu to disable it, but I can't remember now.
If it was in an accident, this would be something to discuss with your insurance company. That usually works out well for our customers.
This happen when my granddaughter was driving the car at night during a dust storm here in the Phoenix, Az. area, She said something flew up in front of the car and nicked the front plastic bumper. The nick is about just a little over a half inch cut on the plastic. After that happen, the warning alert comes on and stays on. I inspected the whole front area and nothing seems to be bent, crack, or broken, being all plastic. Seems to me if something was bent, whatever it was would have done great damage to the front plastic grill. What I am expressing myself here, I told the svc. manager at the Nissan dealer, but, just won't cover it. This happen after two months of buying the car brand new. Anyway, I just wanted for you to here me out and maybe you guys new of a DIY fix. Thanks anyway.
That stinks. Yeah, if it was hit by anything it isn't covered by warranty. I had one yesterday where it was out enough where I had to replace the bracket to fix it, but you can almost never tell by eye. I saw one cracked once, but you couldn't see it until it was off the car. I've had a few that were bumped and body shops sublet it to us after trying to bend it back, cause it's just not something you can see.
