My “Check Engine” Light Has Come On, and What Should I Do When It Does?
When you start your vehicle, the check engine light comes on momentarily to test the engine/emission control system and
bulb. The system is self-diagnostic and the light is a way to communicate trouble. The system is designed to function in a
“limp home” mode when trouble occurs and the light comes on – and stays on. However, take your vehicle Auto Service Department right away (or if you are traveling, to the nearest Authorized Service Center).
Certified technicians have specialized tools and training to access trouble codes stored in the vehicle’s memory each time
the light is illuminated. This is a sophisticated system, with the ability to detect and store information about even the slightest
What Does This Light on my Dashboard Mean?
One item which may seem insignificant but which can cause the system to detect trouble is a loose or missing fuel filler cap.
Remove the cap, then tighten it until it clicks. If you are unsure whether the loose cap was the cause or if the light stays on,
call your technical personels
The light also can come on if you have installed electrically powered accessories (such as a radar detector or keyless entry
system) that aren’t compatible with your vehicle’s systems. If the light comes on and such accessories are installed,
technicians may insist they be removed or disconnected before any further diagnosis can take place. Subaru-approved
accessories are thoroughly tested to prevent such problems.
