MR2 Check

MR2 owners know diagnosing their vehicle requires setting a jumper pin and interpreting flashes on "check engine" light on the instrument panel. This app, MR2 Check, makes looking up the code no further than your Android phone.

Select your engine, enter the code or codes (space separated), and press "LOOK UP." Enter the code 100 to see descriptions of all codes for the selected engine.

You can also enter the code by pressing the "BLINK" button while matching the blink pattern on the "check engine" light. This takes a little practice to get the timing right, and it helps to record two cycles for better accuracy.
