Yes it does, there should be a black small button under the drivers dash .could be hidden so look with a light, once you find it you need to turn your ignition on then turn it off and press the button within 10 seconds the LED should turn off and the alarm should be working normally
Yes, the LED is solid red. I observed today that it lights when engine is off. But I don't know what brand of alarm do I have. I just bought it with used car few weeks ago. But I read DEI on the viper. Does that make sense?
