Warning lights can drive you crazy. Sometimes all of them are on at the same time.
The engine the parking except the red Brake which goes off when I disengage it, the traction and ABS all stay on while driving. Occasionally they go off while driving, but the next time I start the car they stay on again. OBD2 scanner read U1412 code.
If you look up the code it gives you the following: Faulty Transmission Control Module (TCM) -

A shop where they have $ophisticated $canners pinpointed the issue; The Abs Speed Sensor Front Passenger side is bad and here's the new part in which I'll put the link in the description. This will fit the 2015-2021 Jeep Cherokees all models including the Trailhawk submodels and it's the same part for the driver side. Installing the front speed sensor on these newer jeep models is a breeze compared to the older models. After chucking the back wheels we jack up the front passenger side wheel. Place a jackstand under the lower arm and then lower the jack keeping pressure on it. using a 19mm square socket on an impact gun we take the lug bolts off the wheel. From the 2014-2022 models, Jeep has made many improvements and one of them is the accessibility to the ABS speed sensor, you’ll see what I mean. Start with the cable plug here in the wheel well, then follow the cable to the first grummet that holds the cable in place. The second grummet here. Then the third here and then comes the speed sensor. Notice how easy to get to it. on the older models the caliper and rotor had to come off because the sensor was under the rotor and on the other side of the mud guard. This engineer had his brain linked to a mechanic when he made this modification. it definitely deserves a thumbs up let’s start by unplugging the cable by using a pick tool to release it then pull out the first grummet from the holding bracket before going any further we start inserting the new cable to the first grummet holding bracket and place it in the same position as the old one continue to the second and third grommet and make sure the cable is routed the same way as the old one this assures the cable will not rub on any moving suspension parts while driving. once we reach the sensor we unbolt the old one using a 10mm socket. if there’s a lot of debris around it, it should be cleaned to avoid dirt from falling in the hole. once bolt is removed gently twist it both ways to get it loose you want to avoid breaking it and the rest stays in the hole That would be a bad thing you can lube it if necessary but not go overboard with it once it twists, you can use a pick to pry it at the same time you're turning and pull it... eventually it will come out once its removed. take the new sensor and slowly push it in make sure the hole is lined up, insert and tighten bolt with 10mm socket and don't overtighten. Now plug in the socket but first remove the old one clipped to the wheel-well, by just inserting the pick into the square hole it clips into and pull it out. Now plug in the new one to the socket and clip it back on the wheel-well. Start the engine and drive it so the computer senses the new ABS Speed Sensor and it should turn off all the warning lights, so make sure your wheel is back on and torqued, take the jackstand out. As soon as i backed out of the driveway and about to put it in drive; all but the engine light went off, if that happens; plug in an OBD2 Scanner.place the ignition to accessory without turning the engine on run the diagnostics and then go to erase codes once the scanner acknowledges the codes have been erased, the engine light will still be on until you start the engine and you'll notice the engine light turn off.
