Viper alarm keeps telling my hood is open when it is not

My emote start worked fine yesterday morning but did not yesterday afternoon. I keep getting the error message that my hood is open. I checked online for a solution and I found most said it was the underhood pin. I have searched everywhere under the hood and cannot find a pin.

The first thing you do is check the plug where it plugs in to the sensor, next you might be able to adjust the switch, see if there is nut to adjust. If that does'nt work then you will probably have to buy another one. I hope this helps

SOURCE: service engine soon light

If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything from a loose/faulty gas cap to a transmission issue.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain on. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially turn on.

Antitheft system keep goes on so i can't start my vehicle


It is telling me to lock the doors with the key, this will arm the system, then you should be able to unlock the doors after about 3 seconds and this should disarm the system. Also, if it doesn''t try unlocking the passenger side door or the back glass with the key. Let me know you must wait at least 3 seconds before unlocking back glass or passenger door to disarm system once one door is unlocked without setting off alarm it is disabled. hope this helps

Antitheft system keep goes on I can't start vehicle


Use the remote to deactivate alarm or use key in the door lock to unlock the door. The problem you had is when you lock the door and the alarm activates it must see a disarm signal or else it thinks someone broke the window and used the switch to open the door.

I replaced a battery in my 2001 pontiac montana n the lights started blinking as if the alarm was going off.i hit the unlock n lock button n the blinking stopped. i have power,lights n radio but van wont...


It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.


There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

Factory security system intermittently going off. Wondering if it is a bad sensor or switch. Does the door LED flash a code? 8 long flashes followed with normal short flashes.

Car is not starting when damp


Lincoln town cars are famous for this because the rear opening to the hood has been placed right over your distributor so; the rainwater just soaks your distributor. to fix this permanently get a piece of oil roofing paper cut it about 6' wide and glue it over the gap from under the hood this will keep your distributor dry
