Question about 2005 Jeep Grand Cherokee
The perform service light comes on for about a minute after starting the engine, then disappears. I used the code reader under the dash and nothing appears.
i guess you lost the operators guide, as do most post here.
its not an error, DTC are errors
the 05 that is a DO SERVICE light, all new cars have this.
the way it works is
lamp comes on
they do the service, and they turn it out
or you do it and then turn it out.
so then you ask, how to turn it off.

or get the operators manual.
here it is for free.
down load it and keep it. (read it, it covers this 100%)

A loose gas cap will sometimes trigger the service light to come on. Since this appears to have happened on multiple occasions I can assume that this is not the problem but may be associated with it. The level of gas in the tank affects the amount of atmospheric pressure in the tank. There are multiple things that could set off the light, one being a loose or defective gas cap, and the other is a fuel vapor return valve. I'm not sure of the exact type of fuel system you have so I cant give a more exact answer. If you wanted to give something a shot before bringing it into the shop, you can simply replace the gas cap first, a very cheap try.

There is no way for you or me to tell. In order to determine what service it needs you should go to the dealer and they will perform a diagnostics test. I think it is around $95. It could be something simple as a fuse or reset needed. It could possibly be under warranty and not cost you anything but the $95.
I hope this helps

Actually the newer cherokees are a little more complicated, it's not a reminder for an oil change. It is for an emssions service that should be performed according to the dealer. Here is the rest procedure
Turn ignition to on position, but do not start.
Depress brake pedal fully twice.
depress excellerator very slowly twice
Turn ignition off & that will reset the perform service indicator.
I am mechanic & we are getting frustrated because the dealers do not want to release this info to anyone, they want your money! Can you believe if you did not get them to perform the service they charge you a 1 hour shop rate??
