VSC lights on code is C1249 and C1223. Brake switch replaced 4 months ago. What to do next?

Note: I am the original poster

My mechanic (another one from the mechanic who installed it) checked the installation. He is a Toyota Lexus mechanic, he said it is correct. I pointed out to him that, the brake lights stay on after I turn off the car.

I pointed out to him the attached photo. I see that there are threads on the nut bolt, by making an adjustment, it can release the brake pedal more towards up. I wonder if this can help.

The car brake lights in the back stays on when turned off. The warning lights come on only when I start drive.
Somehow, the car computer thinks that, while brake pedal is still being depressed (due to whatever problem it is) the gas pedal is also pushed simultaneously so the warning lights are coming on, IMO.

My mechanic also checked the wiring that goes to the stop light switch. He didn't see anything he says.

Been trying so hard to make this go away.

done brakes or an axle shaft recently?? check the wheel speed sensors

That code refers to an open Brake light switch. Google "Code C1249" to get more specific answers for your model.

check the drive shaft if they are dry if wet clean them

the switch is at top af brake pedal and is easily checked pull off the connector and bridge the two wires if lights come on then renew the switch if not check fuses etc

Whenever engine fault codes set, VSC is disabled and lights come on. P0020 shows failing cam shaft position sensor , recommend replace clear codes and recheck. gas spill was coincidental.

Same here. I stopped by Autozone and they gave me the following codes. P0020, U0126, U0124, U0123, U0073, C1223 and C1201. The only thing I did was splash some fuel the day before at a questionable gas station. Please help

C1223 - Left Rear Wheel Speed Sensor Input Signal is 0 C1203 - The procedure for this fault is to check for an open or short in the harness and connector between the Skid control ECU and ECM.If no faults are found with the wiring, then - the MIL stays off when ignition on but engine not running (Requires ECM replacing)
- the MIL comes on when ignition on but engine not running (requires ABS & traction actuator assembly)
These parts wont be cheap so i hope its a wiring fault
If you take it to a Toyota dealership they should be able to do this for you pretty easily.

try disconnecting the negative cable on the battery for 15 minutes then reconnect do this a couple of time if not you may have a module problem being that it's not recommended to jump start a vehicle that's equipped with pcm of any kind good luck

PROBLEM IS R/R SPEED SENSOR--ALL OTHER CODES ARE A RESULT OF THIS--SENSOR LISTS FROM TOYOTA FOR $136.06 AND LABOR IS 1.3 HRS AT WHAT EVER LABOR RATE AT DEALER IS---SOUNDS TO ME LIKE YOU NEED TO FIND ANOTHER REPAIR SHOP
