I too know the frustration of Subaru check engine lights. The quick way is either black tape over the light on the dash or remove the bulb. Keep in mind that although you may know the code and the problem (both of mine routinely issue P0420 for a catalytic converter even though I've replaced same more than once) there may be additional problems crop up and you will get no additional warning. --Ken
With the proper scan tool.
Not necessarily.
I want to check the level of atf temp in my subaru forester 2010. On checking the transmission fluid level, after the car was driven about 10 km and was put in each gear and setting the select level in the "p", do i have to turn off the engine or idle the engine before i check the atf level?
Have vehicle scanned to determine the problem
you need a scanner to scan your cars computer to see what is causing it to happen
I had the same problem on a '99 Forester. It was cured by altering the code number on the alarm system. Check the booklet that came with the vehicle for details.
You have a problem with the engine controls, have the codes read at the dealer or an auto parts store and make the necessary repairs and the light will go out, or it can be reset by the tech.
The first thing to do is check all your fuses.
you could check on eBay first, but your best bet is a subaru dealer
My heater doesn't go cold. But to answer your question, check the engine coolant level in the radiator. Be sure that the engine is cold before removing the radiator cap. --Ken
Yes they do offer this, at least they did on my 2000. Check your owner's manual.
Replacing the battery was not likely the cause of your check engine light. Most auto parts stores have a code reader will read the code for you at no charge and reset the light.
