viper 5204x w/remote st

If the cluster doesn't see a start signal, but the car starts normally, PCM ECM will register a running car and no codes will be thrown. I don't see it as an issue.Ted

I've connected the remote start as you've suggested and removed my clutch bypass relay. Now I'm having a problem with the learn tach function, again. A little back story, I had to pull the entire alarm/remote start out to hunt down a problem I was having. Ended up being a problem with a connection in my VATS Bypass. Before I pulled out the Viper, I performed the Learn Tach function and it work without problem. I've reinstalled it. Now it won't perform the Learn Tach function no matter how long I hold the control button???? I've checked my Tach signal from the t connector and I'm getting 5.xx Volts.

check to see if you might have accidentally bent any pins into the unit. you shouldn't need to program tach if you already programmed it the first tie.Ted

I was wondering that. I was assuming that after an extended period of time without power the module would revert to default mode. So you're saying the first time I programmed it, it flashed the module? If I don't need to reprogram the tach learn then I have another problem. I can't get the MTS remote start to engage when I'm shutting off the car. Thanks!

if you cant enter reservation mode, its either 4 things. No tach signal, no door trigger, no ignition, no ebrake. Start checking those any remote start diagnostics? Forget to ground the BLACK/ white neutral safety wire and plug in the switch?Ted

Yes on the remote start diagnosis. When trying to use the remote start I get the parking lights flash 7 times. "7 flashes Timer mode/Turbo mode/Manual mode error * *Manual mode error: MTS mode not enabled." When installing the viper, I connected all the remote start (H3 harness)wires before connecting the harness to the module. Using my multimeter I insured I was getting proper signal from each wire at the correct phases. I know the tach wire connection is giving signal to the wire. I also know the connection on the ebrake wire is giving a ground signal when the ebrake is engaged. I have the neutral safety switch attached here. I don't know the harness is getting the signal, but have no reason to think it's not. I'll check the door triggers. I have a little bit of a complicated setup here connecting to both door triggers using diodes to insure one door doesn't trigger both indicators in the bcm. Each BCM wire connection got two 1 amp diodes. I know the connection for Viper wire was giving a signal albeit not a particularly strong signal. H2/6 GREEN (-) DOOR TRIGGER INPUT (N/C* OR N/O) USE DIODES Preventing a Current from traveling BACK to the BCM and you can bridge the three BCM D11 GRY/BLK Driver Door Open Input BCM D12 BLK/WHT Passenger DOI Thank you very much for the help!

Sorry I didn't finish the following thought. Using my multimeter I insured I was getting proper signal from each wire at the correct phases. This was done at the harness that connects to the Viper module.

btw, the BLACK/ white is suppose to get the ground from the ebrakeTed

Yes that's exactly what I used. H2/2 BLACK/ WHITE (-) NEUTRAL SAFETY INPUT

you listed it as a chassis ground on your initial post.Ted
