I just finished installing a Python 991 into my 1997 Civic Hatchback along with the 530T. Almost everything works as it should except for the remote start and the light flash output.

I set the polarity on the light flash to positive and connected it to the red/black wire along side the sear passenger seat. I get 12v pulses from the alarm when testing with a DMM. Not sure what else to check.

The remote start errors with 7 beeps/LED flashes which suggests the alarm is not in MTS mode but the manual states that by default, the settings are MTS mode enabled.

I can't get into the programming functions of the alarm unit. I turn on the ignition, the turn it off, then hold the Control Center button down while listening for a siren chirp but I don't ever hear it or see any LED's flash. I do sometimes get it to go into Valet mode. I've also tried to return the unit to factory default settings but can't seem to do that either through the control center button.

I know the control center works because I was able to pull the diagnostics from it. Not sure what else I can do.

 

Did you make sure to put the included fuse into the brain for the light flash?

 

Yeah, the fuse is present and connected in the "+" polarity position.

 

As for the remote start, It's not getting passed the initialization procedure. I've manually grounded the neutral safety wire, bypassed the clutch, and checked the brake shutdown again. All are good. My tach wire is going to the gauge clusters solid blue wire.

Here are the main connections from the H3 harness

Red/Black, Red, and Red/White - White wire from my ignition.
Orange - Yellow (+) from my ignition.
Pink - Black/Yellow from my ignition
Pink/White - Yellow from my ignition
Green - key side of starter
purple - car side of starter

Anywhere else I should look?

 

Got the lights flashing. It was just a poor connection. So I tried the remote start procedure again and now theres 5 flashing lights which indicates an active brake wire during remote startup. The brain does something strange during the manual tranny process; it turns on all brake/flashing flights before you are instructed to get out of the car. Is this normal? Such is why the brown wire is seeing 12v and flashing 5 times...

 

Not sure how your trying to follow the instructions on manual remote start when you said you grounded the Netural saftey wire that suppose to go to the parking brake.

 

Yeah it was just for troubleshooting. That neutral safety wire looks for a ground. So all I did was put it a good ground when instructed to pull the ebrake. I just thought it may have been that wire causing the halt on the remote start process.

 

So i figured out more than half of my problems with programming. A poor connection was made from the green trigger wire to the door wire. So I'm able to do the programming I want. The priority lock works, the horn honk works, and a few other features work really well. The only thing still wrong is the remote start. I cannot get it to initialize. I get passed the setup steps, then I press the lock button and it fails to remote start.

 

I did the sequence many times and it never remote starts on the last step. Isn't it dangerous to have it in auto mode on a manual car?

Also, when testing voltage on IG1, the voltage drops to 8v when cranking, is this normal?

 

You do not program the alarm to auto if its a five speed period! The ignition wire should stay solid 12 volts during remote start as it comes from the battery when the key is switched on. Do you have a back up battery trigger going to the blue instant trigger wire? If so you need a relay to isolate it during remote start. The remote start need brake, parking brake, tach to work. and door trigger.

 

Didn't know about a relay for the backup battery. How should I wire it?

All other triggers are working as they should.

 

Additionally, during remote start, the car never cranks. Not sure if this would provide any more useful info. I did test all of the power wires going back to the alarm, they all show 12v or more. All other H3 wires are making good connection to the alarm brain.

 

Going by what WRX stated, I disconnected the instant trigger form 520t to alarm. It still will NOT remote start.

I did enable auto mode to see if it works. And it does. I've double checked all remote required wires. Not sure where else to look.

 

The problem with the 520t and the instant blue trigger wire. Is during cranking of the car. The 520t senses voltage drop and shoots a ground out to the instant trigger. This causes the newer dei brains with remote start to trigger the alarm thus shutting off the remote start. If the car is a 5 speed this means you with have to start over the reservation mode again or disarm the car before remote start.

You need to check to make sure the black/white is going to the hand brake, Brown is going to foot brake and door trigger is tagged correctly and try the reservation mode again. If it fails the error codes will flash to tell you whats wrong. Its something in your wiring job. If the car starts in auto mode. It should start in manual mode.

 

Okay, here's the problem. My Python 991 is a "newer" model with a 16pin connector as opposed to the manuals on the web which has a few AUX harnesses for remote start and such. I located the manual for my "newer" model and have found that the MTS procedure is totally different from the old version. Here's how it goes:

1) when ready to park and leave, pull the hand brake
2) press the foot brake
3) press any button on the alarm key
4) remove keys from ignition
5) step out of the vehicle, press the arm button on the alarm key.

After doing this, I was able to remote start the car WITH the 520T's instant trigger connected. So I know it works and I know I will need to do this EVERYTIME I want to remote start the car the next time I want to drive it. I'm fine with that.

But...When I do this, the alarm activeates the DOMELIGHT SUPERVISION relay which is connected to the thick lt.green/red door trigger wire. So when I step out of the car on the last step, I have to wait for the domelight to shut off before I press the lock button. Otherwise, the alarm will think that a door is open causing the MTS mode to halt and fail. I find this annoying if I have to wait until the domelight stops activating.

So. The install manual says to connect the domelight supervision wire to the wire that turns on the domelight through a relay of course. Which wire actually turns on the dome light? I'm believing that the lt.green/wire is a trigger for it to come on when opening a door. Isn't there a wire or 2 that runs directly to the domelight? In other words, I'm wanting to go straight to the domelight without interupting or triggering the door switch during MTS preperation. What polarity is it? Location? I'm almost finished with the wiring, now just to complete this....

 

And it just hit me that on the final step, arming the alarm, the dome light should turn off. Now I don't have door panels on at the moment. Could it be that the switch on the door is not being pressin in all of the way?

 

The first gen and second gen python there is no difference in the remote start mts. Not sure were you got that information. The only difference is the the anttena plug and remote start pin harness. Thats it.

And from looking at what you posted. For the mts. Its wrong.

press and hold the parking brake while pulling up the e-brake. let off the foot brake and press the remote start start button. The light will flash 3 times, take the key out of the ignition. The car will run open and close the door and arm the car. The car will lock and shut off.

Its was never the way. I have all three sst models here, (991, 5901, 50.5x) and none of the instructions state that.

 

Yeah that's what I thought but it was not working for me until I opened my manual to take a look. I was thrown back by it. Very trippy. I'll have to scan it and upload it for you to see. But after enabling it this way, everything is working just as it should with the exception of the door trigger/domelight issue.

Additionally, I want to add 2 more sensors. The 506T and 507M. I believe I can use additinal sensor port for the 506T. I'm more concerned about the GWA and Instant Trigger wires. I will have to use diodes so which way are the cathodes supposed to face when installing them outside of the additional sensor port? Currently, I have a 530T to the GWA on the alarm, and the Backup battery to the blue Instant Trigger. Or can I tie these 2 sensers together and use one plug to the sensor port?

 

very informative, as i'm about to do this same install.

 

Just read the manual that came with your alarm. I don't know how many different versions there are out there. The installation is rather simple, study the manual more than 3 times and research. Plan the installation carefully because you don't want to go back and redo all of that pretty wiring due to one problem.

As for my probelm, the brain activates the dome light supervision output during MTS process. Really strange.

 

^^^ not sure how the brain turns the light on. Are you using the are dome light wire to activate it? black/white.

 

Yes, I'm using the b/w wire from the brain to a relay. When I go through the MTS procedure, the parking lights flash 5 times as the manual says it would, then it pauses for a half second, then the b/w activates the relay which turns on the dome light. At the last step, I exit the vehicle, and arm the car which deactivates the dome light but then the remote start fails as the remote indicates. This DOESN'T happen when power is NOT supplied to the relay controlling the dome light, or if i wait until the relay switches the dome light off.

Is there a wire that turns on the dome light WITHOUT trigging the door triggers?

 

Would anyone happen to know what happens to the ignition lead on the car during MTS procedure? At any time, does it shut off dropping to 0v? Or does it stay live until exiting the vehicle and pressing the arm button on the remote?

 

Well I figured out the problem. Kind of. I tested IG1 for any voltage drops during MTS mode, there was none. But the alarm brain is sensing the ignition is turning off thus triggering the b/w dome light wire to activate. So I went into menu 2 option 5 and set the alarm to not turn on the dome light when the ignition shuts off. Now I can go through MTS procedure without failure or having to wait for the dome light to turn off. I'm not sure if this is a fault of the unit or a limitation of DEI's remote start. But I'm glad I got it figured out. I hope this helps someone in the future.
