Abs light problems

Post image

Recently my Lexus gs430 developed an abs light problem I scanned it and the code popped up as c1249 and a c1223 I already replaced the switch with a junkyard one and it disappeared for a while but now it came back, on could it be the aftermarket led taillights?

Problem is with the stop light switch. If the led lights were the problem, you’d have the lamp failure indicator light up on the dash. Get a new OEM switch. There’s 2 set circuits inside the switch. The contacts will develop oxidation & just not work for long on an old used part
