flcan bypass on viper 5701

Hi all!

I need help programming an Audiovox FLCAN FLC-AL(DL)-CH5  bypass on my Viper 5701 alarm/remote start.

Try as I might, it’s just NOT acting like the instructions say it should and I’m unable to get it to “learn” my key.

Here’s the skinny – bear with me as I’m long-winded:

I have a Jeep Liberty 2011 with a Viper 5701.

The 5701 was installed by a dealer and it has been functioning great.I wanted more range, so I purchased the antenna and LCD remote that come with the Viper 5901 – DEI said that would work with the 5701.I purchased a Bitwriter and recorded every single setting available just in case I lost the settings when I paired the new remote/antenna combo.Swapped the antenna and paired the new remote – no probs so far.All was well for every function EXCEPT Remote Start. When I tried that I’d just get a remote start error on the keyfob.There were NO parking light flashes to indicate errors.I decided the bypass must need to be reprogrammed to my factory key again.I reset the FLCAN unit to factory defaults per the instructions I got from Audiovox – it’s the FLC-AL(DL)-CH5 unit (unplug cables, hold programming button in while plugging the 4-wire cable back in – release the button, etc.)

Now the annoying part…

The instructions then say that to reprogram the unit to my key I need to:

1) Press and release the programming button (on the FLCAN) to select the installation mode – 1 flash=DATA MODE, 2 flashes=STANDARD HARDWIRED MODE and then HOLDING the button to choose that option…NO CAN DO. Pressing the programming button does nothing – LED stays off. I have a feeling that there are possibly Jeep-specific hoops I need to jump through BEFORE I press the button to choose a mode – like open door, close door, pat head, rub stomach, etc.

2) I tried HOLDING the button in. This causes the LED to flash green once (delay) then twice (delay) then 3 times,… until it gets up to like 9 or something and then it starts over at 1. If I release the button the LED goes out and if I press and hold it again it starts the same routine over.

3) I’ve tried doing this with the door open, closed, key in, key out, key ON, key OFF…no go. I actually got it to darn near act like the instructions by opening the door and leaving it open, holding the button down for like 2 minutes until the LED flashed RED once over and over.  I hit the button again and got 2 RED flashes. I took this to be hardwired mode. I pressed and held the button again and got solid green which the instructions indicate should be happening. I put the key in and turn it to ON and the LED just stays solid green even though it’s supposed to switch to RED and then flash green rapidly. I don’t know exactly what I did to get this all the happen, but I managed to stumble across it a couple more times and tried the whole routine with both programming modes (not sure which I want anyways – I figure hardwired mode…?)

Anyways, sorry to draw this out – you get the picture…

What am I missing?

I’m hoping there’s someone out there that has used one of these FLCAN units that can tell me what’s in the secret sauce so  I don’t have to break down and bring it back to the installer and deal with that whole mess…

Thanks everyone!

Try this to set the installation mode.  1.)  Do the Factory Reset up to & including Step 5.2.)  At this point the module is reset and if you continue to watch the light it will       start doing a quick single green flash.     a.)  This is Data mode.  If you want Data Mode, just press and hold the button until           the Green light comes on steady to lock it in.     b.)  If you want Standard Mode, quickly press the button.  Now the light does a double          green flash, then press and hold the button to lock it in.3.)  Continue with Step 6Soldering is fun!

Thanks SO much for the quick reply! :)

Makes total sense!  I guess back at the time when I did the factory reset I did notice that the LED was flashing green, but I must have moved on and done something else not realizing that was my only chance at the proper programming mode :)

Here's another question for you - WHICH mode do I want? If I just want to "learn" my key would I choose the WIRED (standard) mode? Is the DATA mode for upgrading firmware? (read something about that in my HOURS of scouring the internet)

Thanks again!

The Installation Mode has to do with how the bypass module will communicate with the Viper.  In the

install guide, you would follow the Type 3 diagram.  Loaded with the FLC-AL(DL)-CH5 firmware, theFLCAN is capable of 2 way D2D communication with the Viper thru the D2D harness. That would meanall of the dashed Orange connections are handled via the D2D harness.  This is "Data" InstallationMode.

If you selected "Standard" W2W mode, then all of the dashed orange wires would have to be connected.

Either way the solid Black wires should be wired.

Note :  Ensure that the FLCAN bypass module is flashed with the FLC-AL(DL)-CH5 firmware.  There are many

different firmwares available.  There should be a white sticker that lists the firmware and install guide to use,as loaded at the factory.

Sorry, ignore the note above as the bypass was already flashed and working in your Jeep.  Just look at the wiring to see if the D2D cable is connected.  That will decide which Install Mode to select.

Soldering is fun!

Hiya!

The sticker says:

FLCAN(32)

914B7E8BD8

AL32K1.24

Sorry to be such a newb, but can you tell me which harness is the D2D?

On the LED/SWITCH side of the FLCAN only the first 4-wire harness (DATA MODE according to the diagram) is connected -  Is this my obvious clue as to the identity of the D2D harness? :)

On the other side there are 3 harnesses starting opposite the cable I just mentioned.

I see very few (if any) of the dashed-orange wires (from the diagram) connected so I guess I can be fairly certain I should go with the DATA MODE option :)

Thanks again for your help! You are a MAJOR blessing! :)

Sounds like Data Mode.  There should be a 4 Pin harness from the FLCAN module on the LED side, last port on left.  This harness connects to the Viper D2D port, same side as BitWriter port but far right.

The FLCAN might have come with no firmware loaded and the install shop flashed the module with the CH5 firmware prior to install.

Soldering is fun!
