How to disable trac and VSC in highlander hybrid 2006 model


Disabling the light doesn't fix the problem, you should have this diagnosed by connecting a diagnostic code reader that can communicate with the traction control system, then go from there.

Check enguine light vsctrac light and vsc off light on and transmission shifts funny


Hello, the vsc/trac lights will turn on whenever the check engine light turns on first, this is a fail safe function,vsc and trac are disabled as soon as the check engine light turns on so the check light needs to be diagnosed first, you will need to have the onboard computer scanned for diagnostic codes for the engine control system, these are usually a letter fllowed by some numbers, for example a P0301 code would be an engine misfire on the #1 cylinder. If there is an Autozone store or other autoparts vhain store like advance auto, pep boys etc give them a call and take the truck there, they usually help you get the trouble code numbers at no charge, after you have this information post a follow up with the results and I can help you with a solution.

A p0420 sets after Engine and catalyst are warmed up, vehicle driven within set vehicle engine speed range and waveforms of heated O2 sensors bank 1 sensor 1 and bank 1 sensor 2 have the same amplitude.
Catalytic convertor and O2 sensors need to be tested

The vsc trac and vsc off, plus the check engine just came up on the dash board. What do I do to make them disappear? Its a toyoto 4runner 2004.


For some reason on Toyota and some Lexus vehicles certain check engine light CEL issues also result in the ECU lighting up the vsc trac and vsc off lights. The ECU actually switches these anti skid and anti lock brake systems off and the lights are to remind you that they are disabled. 1) Check that the fuel cap is on securely 2) Check the oxygen sensors on the exhaust, check that connections are clean and there are no missing wires. 3) Have someone check the on-board diagnostic codes if the CEL is still on

2005 Toyota Highlander check engine, track off and vsc light on, what is the problem


there are literally hundreds of codes that would turn on the check engine light. the track off and vsc lights come on together, indicating a problem with the traction control system. again, many different items will turn these lights on. the only way to narrow it down is to hook it up to an OBD-II diagnostic tool and find out all the codes that are listed. if you don't have one, take it to a shop

Dash board,head light,tail ligts stays on when engine is off


The P0420 that you are getting may be an inoperative air/fuel sensor (the actual code is "catalyst system efficiency below threshold". This code will not affect the head/tail lamps or dash lights.
You may have a bad headlamp switch.
