Prestige APS997E, Flashlogic FLcan DL-GM1, 01 Tahoe

First time installer here and im a tad baffled. I cant get the FLCAN to acknowledge my key during programming. Below is what i have hooked up currently, Note i did not hook up a few things with the APS997E due to convenience and courtesy of my Apartment complex.

FLCAN: Reset it, waited for Solid red for Programming, Turn key, Flashes Red, with Ign on and Ign Off

APS977E      TAHOE WIRE
POWER/STARTER 8 PIN
BLUE----------PINK
RED / WHITE-----RED
GREEN---------WHITE
PINK----------N/A
PURPLE--------ORANGE
RED-----------RED
YELLOW--------YELLOW
RED / BLACK-----N/A

4PIN 2nd MAIN
Black-------GROUNDED
WHITE/ Red----RED(on the APS997E)
WHITE/ black--Not Connected to siren
White---------Brown at BCM

26Pin Main
BLACK/ White (horn)N/A
Lt Green------Yellow/RED on FLCAN
GREEN/ ORG-----TACH at Cluster, WHITE
Brown---------TAN at BCM
BROWN / Blk-----White at Brake pedal

FLCAN
Yellow/Red----LT Green on APS977E
Brown---------GROUND
Orange--------OBDII PIN 2/VIOLET
Pink----------PINK AT APS977E Blue to Pink
Im not sure if Purple yellow and purple black need to be connected to the APS997E since I don't have sliding doors....I dont know what to hook them to.



Locks are not connected at this time
Shock Sensor is not connected at this time

This is driving me nuts... any help would be appreciated, and i would love to get this working before the next Ice-age in chicago

I do apologize, this is on a 2001 Tahoe

You didn't hook up the brown accessory 2 wire in the ignition harness...Did you omit this intentionally? I usually hook up all the ignition wires to emulate the key. I've seen this be an issue before--some years need it, others don't...easy enough to use the IGN 3 relay in the Audiovox--tie the thick 8 pin RED / black to 12V, thick 8 pin Pink (ign3) to brown Accessory 2 in the Tahoe. Program the aps997E ignition 3 to "Same as Accy".

Did you use the D2D cable between the FLCAN and the APS997E? If so, don't connect the FLCAN brown--Only the black connections from the guide need to be connected. I assume that the FLCAN is programmed with the correct firmware.

Reset the FLCAN (See guide).

Make sure the FLCAN is in Data mode, then program.


Hope this helps.

yes im using the d2d cable and am in data mode. I did not hook up Acc 2 yet. The wiring diagram i had didnt show a Acc2 so i didn't hook that up. Once i found this site and found the long list of Diagrams i checked and plan on hooking it up later. I am hoping it has the right firmware. theres a slight chance the seller i got it from didnt flash it correctly as i did request an 01 tahoe diagram and they sent me an 04 Cadillac Esculade sheet. Once i get paid i am probably going to have to reflash the thing to DL-GM1 as i requested. The FLCAN sheet shows my tahoe is a Type one Setup

AUTO-RELOCK (-) INPUT - BROWN (shows to Ground)
LEFT SLIDING DOOR (-) INPUT - PURPLE / YELLOW (shows to output to the Remote starter
RIGHT SLIDING DOOR (-) INPUT - PURPLE / BLACK shows to output to the Remote starter
YELLOW/RED - TRUNK STATUS (-) OUTPUT Shows to input of remote starter
ORANGE - DATA (J1850) (to data pin 2 on ODBII
PINK - IGNITION (+) INPUT (to Ignition output)

Are all listed as solid black lines.

When you say ignition wires to emulate the key...how do you mean?

I'd power other accessory wire . Your vehicle and 04 escalade use same firmware . Everything your key does when ignition is on is what you want 997 e to emulate . After factory reset select data mode and don't forget to lock it in. Turn ignition on and then start led should go solid green then shut off on flcan . It's s pretty simple process with gm

but each one has a different wiring setup, i followed Type 1 for DL-GM1 i reset it, lock in data mode, and it doesn't Accept the key

Different wiring but same firmware . Re flashing would not make a difference . Could it be possible that it's not gm immobilizer based ? Or sometimes people use resistors to bypass . What happens when you attempt to remote start it ?

Remote starter simulates key turn to acc, Radio and instrument cluster come on, lights (if dark, thank you GM autolights....) fuel pump turns on, turns over, fires for 1 second.....shuts down......remote system, attempts two more times, then remote states inhibit

The no start condition sounds like a Passlock2 problem which is correct being as the FLCAN did not program properly to your
truck. Here are a few things to know and check.

1. The FLCAN must be flashed with the correct FLC-AL(DL)-GM1 firmware. From the factory they usually get flashed with the
    CH4 firmware. Take a look at the white sticker on the FLCAN package. If you have the ADS USB programming cable, you
    can check this and re-flash if necessary. If you don't have this cable, did you request that the FLCAN get flashed with
    the GM1 firmware prior to shipment?

2. In that year Tahoe, the FLCAM w/GM1 firmware only handles the Passlock2 bypass and provides a Tach signal. This is
    denoted in the Feature Chart on Page 2 of the Install Guide. While it does direct you to the Type 1 Install diagram
    on Page 5, it will not control the door locks, trunk, sliding doors nor provide door status, etc. Going D2D, the only
    FLCAN connections needed ( besides the D2D harness ) are the Pink and Orange wires for IGN and OBD2 data. The FLCAN
    will provide a Data Tach signal via the D2D harness but I would still hardwire the R/S to the trucks Tach wire at the
    instrument cluster.

3. If you are positive that the FLCAN has the correct firmware, try a Factory Reset, then do the Installation Mode programming
    and set it to one blink for Data Mode. Next follow the vehicle programming steps using the ignition key as shown on Page 9.

Do you mean this sticker? taht ha SW: FLC-AD(DL-CH4 2.5? Yes, i did request DL-GM1

Yes, that is the sticker. Without the ADS USB cable there is no way to verify that the DL GM1 firmware was flashed. We can only hope.

Double check / correct the bypass module wiring. Ensure that the Pink wire is connected to the thick Blue R/S IGN1 wire. The Orange wire should be nicely soldered to the Violet wire at the OBD2 plug.
Do the Factory Reset, set the Installation Mode & lock it in. Then try to program to the Tahoe with the key.

Well i just attempted it with just the Data and ign hook up, Failure, that tels me the seller who said they would flash it, didnt not happy...now i gotta find some one to flash it....

Try a local Best Buy. Bring some doughnuts...

well i struck out there, the only way he would touch it is if i let him back track all my wiring -___- at 100 an hour? screw that...i'll spend the 40 and reflash it

The damndest thing happened when i plugged the FLprog into it....NO FIRMWARE flashed it....i now have a working RS

That's good! I came here to lookup what wires need to be connected since the flcan guide is kind of confusing. Your question provided my answer (pink and orange) I'm going to try to install my flcan and 997E on my 99 silverado Saturday.

they just updated the install guide for dl-gm1 firmware as of the 3rd....I only have pink (ign) and orange (obdii data pin 2) hooked in and the data cable...be sure to check if you have 2 accessory power wires...my first diagram didn't show it my 2nd one did and this topic questioned why it wasn't hooked up. I had to program the apse997e to have ign 3 to act as acc 2 to get my hvac system up...just don't do this in 0 to 30 degrees...I did....

Now my next thing is...how can I disable the headlights after start? I know the override for when I'm in it...but...when I'm not near it and I remote it

Hello again, need some more help on my 01 tahoe. I know its a positive trigger and need to rig in the relays to this but i remember some where theres a 2nd unlock wire on my Remote starter system and don't know what that does...is it just the trigger to unlock all? and where do i tag that into? or dont i?

Vehicle: 2001 Chevrolet Tahoe
Engine: 5.3L V8 LM7
Accessories: APS997E and FLcan Passlock Bypass

The 2nd Unlock wire would be used if you wanted "progressive Unlock", where the first press of the remotes Unlock button would unlock only the drivers door. A second press of the Unlock button ( within 3 seconds ) would unlock the rest of the doors.

so what do i wire that to? the relay to the unlock?

I am a figment of your imagination...A girl that works on her own car

Do you really want or need Progressive Unlock? While the APS997E has a 2nd Unlock output, it doesn't have to be used.
The point is, adding progressive unlock to that car via the drivers door unlock motor wires requires additional parts
( 30/40 Amp SPDT relay w/ 5 wire harness and an inline fuse holder with 15 Amp fuse ) and a bit more work locating,
testing and soldering.

If you just want the R/S to be able to control the door locks, get a Directed 451M door lock module, obtain the 451M
Installation Guide in the Downloads section and follow the Type A wiring using these wires in the truck :
POWER LOCK            LT. BLUE (TYPE A)       @ BCM, BROWN PLUG, PIN A4
POWER UNLOCK          WHITE (TYPE A)          @ BCM, BROWN PLUG, PIN A3

Here is a photo of the wires at the BCM :
