Check Engine light and traction control light stay

my car I got a 1999 lexus es300 and the ligt of ECR is tur on, what is it ?
Itried to scan with my bosch tool but nothing appeared.

Any time the check engine light comes on the traction control will be disabled and the light will also come on. Start with scanning the engine computer for trouble codes to see why the check engine light is on.

Take the car to a repair shop and find out what the code is, most likely a wheel speed sensor

It is contained in the ECM and The ABS controller

Check oil level sensor, replace if necessary. also, does your engine knock or make a tapping sound?

Those lights indicate an issue with ABS or traction control systems. In order to properly diagnose the problem the vehicle's codes will need to be read with a scanner.

Generally speaking there is no danger in driving the vehicle but be aware you may not have functioning traction control and/or ABS while those lights are present.

vsc shuts down any time check engine light comes on. repair engine light problem, reset computer monitoring system and vsc light will go off. must scan computer to pull codes for check engine light and go from there.

well, the first to do is an oil service to your car, after disconnect the negative battery terminal few minutes to reset
