VIP Alarm V3



I'm assuming the reason for the error beep is because the door ajar light shares the same circuit as dome light. Hence when you try to arm the alarm with the dome light still on the alarm system thinks that one of your doors is not closed all the way and give you an error beep to let you know you need to check.

This part is very important, "If you purchase the power package you get a tachometer and a DIMMING DOME LIGHT, which is what causes the problem."

Toyota will not install this alarm into a Yaris with a tachometer because Toyota the Manufacture says NO. Toyota will install a factory alarm system (VIP) into any Yaris that doesn't have a tachometer.

Hope this helps.

Interesting. The solution is to use the door courtesy switch inputs to the ECM rather than the ILE output from the ECM as the door closed/ajar feed to the VIP.
