I turn to this forum once again for help. The last time I needed it, you guys came through and made my life easier. Thank you.
A friend of mine wants to install an automatic start/alarm system in his new 2012 Chevy Colorado. I offered to help. I checked online and it doesn't look like they have a Fortin unit available for this application as of yet. I checked the DB-ALL and apparently that one will work. When I was having issues with my Altima, the DB-ALL was my main problem, I got the Fortin and everything worked great. I am hesitant on using the DB-ALL on the Colorado because of my past issues. Does anyone have any experience with a 2012 Colorado or similar? Not sure if the 2011 or any other model year are the same. Will the DB-ALL be an okay option or is there another. Thank you in advance!
Haven't tried a DB-ALL on a Colorado, but going by iDatalink info, starting with the 2008 models, Chevrolet did something
to the Passlock2 that made it very difficult for Data Mode bypass modules to reliably function. Due to this problem, they
recommend doing the Passlock2 bypass the "old school" way with relays and a very accurate resistor value. Here is a link to
the Passlock2 "relays and resistor" method from Audiovox : https://documents.audiovox.com/700054.pdf
Here is the warning info from iDatalink : ( Posted in 2010. )
H3, Colorado & Canyon Passlocks
H3, Colorado & Canyon 2008-2009-2010 Passlock Tamper Mode: Please read the following before installing.
Passlock is not covered by the module on these vehicles because the BCM doesn't adapt well to external passlock modules.
Vehicle BCM internal power fluctuation which occurs in many different circumstances negatively affects external passlock bypass reliability.
When such fluctuation occurs the risks the vehicle going in tamper mode during remote start are high. The bypass module provides you a
highly precise (0.002v) passlock value, the module will not fluctuate when the BCM does which can result on the BCM and module not being
on the same comparison scale. If such situation occur the vehicle will probably go in tamper mode.
The IPC reference wire must be used as the sole Passlock reference in these vehicles to avoid Tamper Mode.
We recommend using relays and very accurate resistors on these specific Models/Years. (the Module will still take care of the PK3 immobilizer,
OEM alarm and doorlocks).
That being said, I did use an ADS bypass module ( without relays ) on a 2008 Colorado, soldering all connections, several years ago and it has
been performing flawlessly ever since. ( It's a neighbors truck that I see often.)

Soldering is fun!
I really appreciate the info and I will take a look into both options. Possibly try the DB-ALL and see how it responds. Thank you!
i always use the 2 relays/resistor method and have never had an issue, very easy truck to do just did one yesterday, if truck doesnt have trailer tow pkg, brake lights is a light blue in the harness going up the a pillar on the driver side( can get it from under the dash)
