Chevrolet Silverado 1500 1999-present How to Reset Change Engine Oil ... "Change Engine Oil" light.Disable Service Engine Soon Light - Aug 21, 2013 · General Technical & Electrical - What does the flashing "THEFT" light mean? - I recently got my 2002 Ranger and I notice that after I turn the key off I see a flashing red sign saying THEFT to the bottom right of the speedometer. It flashes on and then off every four or five seconds. To my knowledge there is no alarm. I made a mistake this afternoon while trying to enable this plugin and had problem with my website after that. I sent an email to their web support service (note that we are sunday) and they solve the problem in the hour! even my developper couldn’t solve it..
