My battery ran low and I jump started my car which some how caused the problem. My viper technician made me a buy new remote but the problem continued even with the new remote.
Try disconnecting the battery of your car for ten minutes and then reconnecting it. It worked for me. Now i have a extra remote which i don't need.

Let's hopethat the installer actually put in the valet switch for the Viper! Lcate the valet switch. ALWAYS put mine down by the e-brake lever under dash. (I assume that the alarm is going off? If not, go to next step.

Find the alarm/start brain under dash. Unplug main 6 pin 12 gauge wire harness. Wait 5 minutes, then re-appy the power plug. Alarm "may" go off, then try again.

Hit me back if you need further assstance. TTYL

Reprogram the remote: turn ignition on, press and release valet switch one time. Press and hold valet switch. While holding valet switch, press lock button on remote. The alarm should chirp to confirm entry into the programming mode (when you press and hold the valet button) and when you press the lock button. Turn ignition off. Test remote.

The parking light flashes are a diagnostic report to alert you to the reason the remote starter is not working:

5 flashes; brake wire is active
6 flashes; hood pin is active
7 flashes; manual transmission mode is enabled and not initialized
8 flashes; neutral safety wire has no ground or the switch is OFF.

Count the flashes and you will be able to go directly to the problem. Enjoy.

Hi! As a first course of action please remove the positive battery connector and let it sit for 5mins. then reconnect it. This will reset the system and can get rid of the problem. Please write back on the progress.

The original remote is the 479V; you can also use the 472V.

there was a recall on these units for the antenna. Unplug the antenna on your windshield, let it sit for 5 minutes then plug it back in. You will need to contact your authorized dealer to replace it under warranty if you are the original owner of the system.
