Check light,and Light is AVS and traction icon.

First you need to have EBCM - electronic brake control module check for DTC'S - diagnostic trouble code's . If the light is on there is a code stored . I think most part stores can do this and for free . After you find out what code is stored , looking up that code in service repair information for diagnostic trouble shooting chart would be next step . There are a few codes too.
DTC C0035 or C0040
DTC C0045 or C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0186
DTC C0196
DTC C0201
DTC C0240
DTC C0241 or P0856
DTC C0244 or P1689
DTC C0245
DTC C0283
DTC C0287
DTC C0290 or C0292
DTC C0455
DTC C0550
DTC C0558

Find the code do the diagnostic's , fix the problem , wiring issue's , a sensor , bad module ,what ever it is . The light will go out then . Here is a sample of code discription .
• DTC C0035 Left Front Wheel Speed Sensor Circuit
• DTC C0040 Right Front Wheel Speed Sensor Circuit

When you have a check engine light come on, the traction control light and the cruise lights both come on as well. You need to have the codes checked with a scanner. There most likely isn't a problem with the traction control or cruise systems, the lights turn on because those systems work together with the engine management system or PCM. When there is an engine problem that sets a code that turns on the check engine light, it automatically disables the cruise control and traction control for safety reasons. Because the last thing you want is to have an issue with traction control and/or cruise control if your engine is having an issue, which is why they are disabled. The most common problem that turns on the check engine light is a loose, cross-threaded, or snug but not tight enough fuel filler cap. Subaru recommends three clicks of the cap to be considered tight. Also, any parts store can and will check and/or clear codes for free. I hope this info helps!

The Passlock system temporarily lost contact with the key

Reduced power is a problem with electronic throttle contol . drive by wire . Do you know what this is ? Taking the vehicle an having it hooked up to diagnostic tool an checking for DTC'S - diagnostic trouble codes is always a first step when trying to find the root cause of any trouble light ! And not auto zone , pep boys , or advance auto parts . Thier diagnostic tool will not check codes in all system control modules .

you have a speed sensor going bad use a scan tool to read them or you have one tire thats not the same size as the others

car has detected a problem with itself could be 1 of a hundred things auto parts store will pull code from car to tell you the problem with it

possibly the transmission

sounds like to me that moisture is getting in a wheel speed sensor , I woudl check to see if any of the insulation on the wires is rubbed off

U will have to run the tests for the trouble codes from both lights, they are unrelated, but chances are the CEL is the same problem, the EGR valve, in any event without the trouble codes there are far to many things to turn either light on to venture a guess, that kind of diagnosis costs allot of your money.
