Hi

Sorry this is in the wrong forum, truck is 2009

So, auto elec fitted led taillights with reistors on blinkers and brake circuits. Then fitted aftermarket angel eye headlights with DRLs.

ABS dashlight will not clear
Codes are C1271,C1272 C1273 C1274 C1274 C1276 C277 C1278 C1282 C1283

All four speed sensors are outputting live speed data. There is no center diff lock.

Anyone seen this. Auto elec wants to check loom wire by wire. Is it the ABS controller computer that might have browned out.

Do I need to take to a Toyota Dealer?
