Hi All. New to Jeeps. Just test drove an ‘03 TJ. it was in very nice condition with 74k miles. It had a dashboard light with a key inside a circle. Quick google search reveals it might be a SKIM malfunction??? I see there’s places online you can send the PCM to get it deleted. Will that actually turn off the dashboard light? Thanks for any input. Could there be other issues involved with this dashboard light? Don’t want this Jeep to drain my wallet. It’s not cheap. 21k.
