I have a 07 Tundra Crewmax with a 7" BDS suspension lift and 20" rims with 12.50x35 tires. I have had the truck for about 7 months now and within the last month I have been getting the vsc off light flashing along with the car skidding light on the dash intermittently. Took to the dealer to see what was causing this problem and found the truck to be giving code C1231. The first step is to reset the computer and then see if the code returns. If the code returns the vsc module will need to be replaced per the dealer. Well the problem returned and they are telling me I need a vsc control module which will cost about $3000. I bought this truck from a Toyota dealer with the lift and tires installed by them and it has also been certified through toyota. Long story short warranty company won't cover the vsc module because they said the lift and tires are causing it. My question is to anyone that has a lifted crewmax and oversized tires/rims have you ever had this problem? I want some proof from other tundra owners that this is not caused by the lift and tires, but that the warranty company is just trying to get out of replacing the module. Any information would be greatly appreciated in getting this issue resolved. Thanks!
