Can somebody help me with diagnosing what happened to my car after I installed the Invidia midpie and Tanabe touring medallion exhaust, and all my light VSC, engine, and traction lights are on. Is this something serious ? How would I get this fixed ? Any thoughts would be appreciated.

 

Have you tried disconnecting the battery for 20 minutes to force the car to reset its systems to "learn" the new mods?

 

u mean the negative end of the battery ? or both ? If so don't you have to run setting again for your radio navigation and all that stuffs ? thanks

 

Did u run the code? I had the same problem in my 08 is350. I installed tanabe and invidia midpipe and a few months later I had VSC+CEL and the code was p0430 (catalytic converter below threshold) I thought it was my 02 sensors at first but it ended up being my cats the good news is lexus did it for free since there emissions warranty is 6 or 8 years and 80,000 miles

 

Either terminal; I usually remove my negative cable. Yes, you'll lose your pre-sets AND will have to re-teach the car the express up-down window functionality.
