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.

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

Why is the engine light on along with trac light and vsc light


This could be two seperate problems but the trac and vsc lights can come on when the check engine light does for a number of codes. Have the check ngine light scanned to diagnose the problem. When the problem that caused the engine light to come on is resolved and the code cleared the tra and vsc lights should turn off as well. Rarely they will stay on in which case your toyota dealer may have to do a "zero point calibration".
