06 jeep, python 991

I put in a 991 today for a customer. It went in an 06 Jeep Cherokee Laredo.

The issue I am having, it will not remote start. Won't even crank. I get a remote start error message on the remote, but no parking light flashes.

After doing the remote start shutdown/startup diagnostics, I get 7 led flashes, Timer/Turbo/manual mode.

Here is how I have everything set with the Bitwriter.

Hood switch, normally open
Door switch normally open
Override pulse count = 1
Transmission mode = Automatic
Engine check mode = Tach And I did the tach learning step.
Engine Crank time = .6 seconds
Engine run time = 30 minutes
Activation pulse count = 2
Turbo mode = no turbo mode
Timer Mode Runtime = 10 minutes
Timer Mode Start Count = 6
Timer Mode Interval = 1 hr
Smart Start low temp = off
Smart Start high temp = off
Smart Start low battery = off
Diesel start delay = wait to start input
Diesel start delay time = 15 seconds
Accessory state during WTS = On during wait to start
2nd Status Behavior = status output
Tach Mode Starter release point = 6
Virtual tach fine tune = not initialized
Remote Start safe lock = off
Transmitter programming = unlocked
Feature programming = unlocked

I have the Neutral safety wire going to ground, as well as the neutral safety switch in the on position.

Just to be sure it was not a hood pin issue, I have disconnected the hood pin and taped that wire up.

I believe I got the remotes programmed properly. They both do lock/unlock/and trunk just fine.

This vehicle previously had a remote start of another brand in it. We has numerous warranty issues with the other one, so we swapped it out for the Python. I am tied into the exact same wires as the previous unit that was installed.

Is there something I am missing or do I have something setup wrong causing it to not remote start?

Any advice would be great.

Thanks

Shawn

7 flashes means that the alarm is set for manual transmission mode and the parking brake is not engaged. You need to make sure the BLACK/ white neutral safety wire from the 5 pin remote start wiring harness is wired to the parking brake or ONLY if it is an automatic transmission go ahead and ground the wire.

The vehicle is an automatic and the neutral safety (BLACK/ white) is grounded.

When using the bitwriter, does the ignition have to be on?

Cause I noticed that even though I set the Start activation to 2, it still is only being active on the single button press. Or is that for programming the WHITE/ blue activation wire?

It just seems like the changes I make in the programming are not doing anything.

I think I am also going to check to make sure the door trigger wire is getting a good ground. Its getting its ground signal from the bypass. I have read that the green wire has to see a good ground in order for the programming to actually be written. Is this true?

Thanks

Shawn

The ignition does NOT have to be on.  When you turn on the Bitwriter and press READ, it will read the programmed info from the unit and will also state CURRENT TRANSMITTER is X.  X being 1,2,3, or 4.  When you make changes to the brain and want to save it to the brain, you need to change the transmitter setting to 0  (ZERO) for the changes/settings to apply to all remotes. There is a PDF in the download section of this site on the Bitwriter.

Hope this helps.

I read in the instructions that came with the bitwriter that if you want to set the programming to all transmitters, set it to 0. So that is what I have been doing.

It just doesn't seem like its accepting the programming for some reason. I can't verify the run time programming since it won't start.

And the door trigger I believe is working because if you arm it wait about 45 seconds and then open the door, the alarm triggers.

I am not familiar with the DEI products for troubleshooting as we just picked them up recently. We had multiple issues with the Zenesis products and when I asked my distributor, they recommended the Python units to replace all the Zenesis units we installed. So going through a steep learning curve.

Thanks

Could you list the wires you have connected from the Python 991 to what wires on the vehicle. And what type/brand of bypass are you using?

The bypass I am using is the DLPKCHG2 -CHD7

I will only list the wires I have connected to make is easier.

H1 Harness
RED / White - Trunk - hooked to Orange trunk wire on bypass
Red = Battery
Brown = Siren
Black = Ground
Green = Door trigger - hooked to Pink/White on bypass
White = Parking light relay

H2 Harness
Violet/White = Tach wire
Dark Blue = GWR to Brown on bypass
Grey = Hood Pin This is currently unhooked and taped up
Brown = Brake Switch
BLACK/ White = Ground

H3 Harness
Pink = Ignition Pink/Light Green on Jeep
Violet = Starter Pink/Orange on Jeep
Red = Battery
RED / Black = Battery

Thanks

Shawn

Today, I tried to run a separate ground just for the BLACK/ white wire. I had it tied in with the main ground for the unit. Just wanted to make sure it wasn't a bad connection issue.

Also flipped the toggle switch in the other direction (off) position just to double check it wasn't backwards. Still same issue.

Zapped the programming and started over.   Reprogrammed the remotes. Still getting the same issue. And then the one way remote stopped working. Thought maybe it lost the programming somehow. Worked fine when I reprogrammed it after I zapped the unit, but picked it up to try the remote start to make sure it was not just the 2 way remote having an issue with the remote start, and it lights up, but wouldn't lock or unlock the doors. So tried to reprogram the one way and it won't go into programming mode at all. Tried the to put it in Auto learn, and still nothing.

So all that is left is possibly a defective unit. Got another one in route to see if that cures the issue.

Any other insight of something I am missing? Or I am right to assume the unit is defective?

Thanks

Shawn

The DLPKCHG2 takes care of the second start/accessory wire through the MUX wire.

I don't feel the issue is with the bypass though. If it were the bypass, the vehicle would at the very least crank over.

This one is not even cranking over. Just instantly goes to remote start error on the 2 way. So that tells me its still in manual mode, or a safety is active. Hood pin is the only other safety used, and it is disconnected and taped up so it can't rest against anything to pick up the ground signal.

It honestly seems like its not accepting programming from the bitwriter for whatever reason. I can set it automatic, but still get the 7 flashes meaning manual mode. Also when I set it for 2 button press for remote start activation, it still only takes one button press to attempt to remote start.

The bitwriter shows automatic, as well as 2 button press activation. When I zapped it, it went back to manual and 1 button press. I changed them both back and still nothing.

I am seriously at a loss.

Shawn

what version of the chip do you have in your bitwriter?  also for the sake of it being in manual mode or not have you tried going through the shutdown sequence as if it was in manual mode to see if it was infact in manual mode?

-------------

I am not sure on the chip in the bitwriter. I ordered it when I ordered the replacement Pythons. I did ask the distributor if I would need the update chip and he said the bitwriter I was buying already had the updated chip in it.

As far as trying it in manual mode, I only got the quick reference install sheet with the Python. And I didn't see where it talked about the steps to start it in manual mode.

Shawn

look up the manual for the viper 5701 on the downloads section of this site and scroll down to page 78.  Where it says engage the parking brake you just need to flip your neutral safety switch to on.  The manual for the 991 is on this site as well for reference. 

-------------

So if it starts by doing the manual setup, what does that tell me besides its in manual mode? Where do I go from there?

If it doesn't that means something is not hooked up properly or one of the components is messed up.

I am gonna pull apart my bitwriter and check to see what it has in it. I know when it boots up it says the version its using, but don't remember what that was. So I will check both of those things out.

So if the bitwriter is not the proper version, will it still read, just not write to the brain?

Thanks

Shawn

This is a silly question but you are using the "write" button on the bitwriter to save your changes, correct? 

-------------
Advanced

Yes I am using the write button. Then it goes to "Write Successful" "Please Wait". Then it takes a second or 2 then goes back to the very first programming option.

After I program it, and go back in with the bitwriter, all the changes I made show up on the bitwriter, but the brain isn't actually doing the changes that were made.

Shawn

ok, just making sure.  in some of the previous posts you talked about "zappin" it

-------------
Advanced

Update. New brain is installed and working fine.

The only issue we are having now, we can't get the sequence on the 2 way for the 2 button press for activation. But it does work fine under single button press for activation.

On the one way, you press the start button, wait about 1 second and press again, fires right up.

This does not work on the 2 way.

So does anyone know the proper 2 button start sequence to use on the 2 way remote?

Also, how do you do the button lock to stop accidental button press activation?

As far as the old unit, not really sure what was causing the issue. Just did the brain swap and changed to tach, learned tach, and did 2 button activation and it works just fine, as long as you are using the 1 way remote. The old unit wouldn't respond to even 1 button press activation setting. We are just chalking it up to a bad unit. I swapped the brain, antenna, and the remotes. So it could have been anyone of those things causing the issue.

Thanks

Shawn

On page 35 of the Python Owners Guide is the info for setting the key pad to "AutoLock"

So the autolock is the only way to lock the remote? It doesn't have a button sequence to press to get it to manually lock?

Thanks

Shawn

It is probably the same as the Viper 5301 & 5701 i have, they are set to lock 60seconds after the last button press. Then use one time on the function button and then the unlock button to unlock the key pad.

Yeah, I can set it for autolock. I was just hoping there was an easier button sequence to lock and unlock the remotes. Not sure why they can't have a lock/unlock button like so many cell phones have these days. The one on the remote is not very user friendly for the customer.

I guess I will play around with the 2 pulse activation sequence on the 2 way. That way the customer won't have to worry about accidentally starting his car with his keys in his pocket.

Thanks

Shawn

I might have an answer as to why the bitwriter would not write the changes you were trying to make.  I was adding a trunk trigger to my daughters car with a Viper 5701. I had tested the alarm and had not cleared it from the memory. I could not make any changes to her 5701 with the bitwriter.  Once I started the car with the key, it cleared the zone alarm and then I could write changes to the brain. Don't know if anyone else has run inot that issue, but that is what I had on this one.

I'm having the same problem installing a Python 991 into a 2007 Escalade. I'm using a Xpresskit DLPK and I can get the rs to crank the truck neither. I get the remote start error from the 2-way remote. Is it possible it's a bad brain from the python unit?
