JSCAN

[BMCGC]

I am installing auto headlamps if the switch ever shows up. I followed the thread that maflivingston posted earlier this year.

maflivingston used JSCAN to enable the auto headlamp function.

My next project will be passive entry. Will JSCAN also enable passive entry? I looked on their website but was unclear as to all the functions available.

If JSAN will not enable passive entry, what's my best programmer choice?

This is my wifes Jeep, when the oem tires wear out, I may be able to sneak in a size larger, otherwise this is all I will be using a programmer for.

AlfaObd can do that too.

It's been a while, but the original monster size thread on this was so large that I bookmarked in it what I thought was the first post in which @Etch first explained the process:

It's possible that things have changed since this, but following its guidance I was able to effect the proximity lock functionality you seek. Of course in addition to JSCAN you will need the various upgraded cables and guidance on how to install them.

The JSCAN, cable, adapter and license runs about $190.

I'm only going to do passive entry on the driver door using the kit. That runs $250.

I wanted to make sure the $190 I spent on JSCAN would also work on the auto headlamps and the passive entry.

I just dropped 82k on a new F250, so I am spacing out my mod dollars every month.

The JSCAN, cable, adapter and license runs about $190.

You should be able to get it all for under $100 ($20 JScan license, plus sub-$20 12+8 cable, plus ~$60 compatible OBD-II Bluetooth adapter).

 

[LAM]

Agree with the ~ $100 total cost. Add in a set of SGW extension cables which makes it easier to connect and disconnect the securitzy bypass cables.

 

[Rhinebeck01]

Reality is a guy that is on a budget lets say, can put together a lets call it, a pretty decent, JSCAN set-up for even less. For about $66 total.. JSCAN license $20, $32 BT Scan Tool and $14 for 12+8 Chrysler cables.

Although ...Personally, I think 12+8 Chrysler cables are laughable and not the way to go. Far better to buy a dedicated security gateway bypass module.

IF one wants to use JSCAN and to be able to deal with all that JSCAN can throw at it, you would be best to go with a VLinker MC+ @$59. The VGATE offering will handle what most guys would throw at it with JSCAN. Buy here:

For those that want it all lets say, go with and OBD Link MX+, an ECRI dedicated security gateway bypass module and JSCAN license and a ZAutomotive security gateway extension cable..... This set-up can be had for say $175-$200 tops. What's nice about this set-up is that someday you will be able to resell the superior set-up and re-coop your $. Not necessarily so with the bargain set-ups.

 

[AndySpill]

Plus 1 for the SQW Extension Cable even though it isn't required.

Having this will allow the sometimes challenging task of disconnecting the factory 12 and 8 pin cables from the factory security gateway a one time operation.

Also, I am interested in hearing more specific details about who and what kind of problems using the 12+8 pin adapter people ran into.

@BMCGC Geo: intent here is not to bash more expensive components like the ECRI Security Gateway Module but have you appreciate that I had no problem adding proximity locks using a 12 and 8 pin cable, and equally important didn't end up buying a security gateway module twice.

Restated, monies for my security gateway module went to Z Automotive whose offering, albeit pricier than the ECRI, isn't simply a security gateway module but provides many interesting features as well. Given you desire to only do one proximity lock, and budget monies, only you can determine your priorities here: all we can do is provide informed information.

You've been thrown more acronyms here Geo than the military has. Hit us back with questions if you'd like a product links and instructions, etc.

Gotta say, this is the way to go. I use both the Tazer and OBDLink MX+ with the finger-saving Z-Auto security gateway extension cables neatly tie-wrapped way up behind the dash, just waiting for when I need them. Absolutely zero issues with either module alone or in tandem to date.

Oh, and thanks Mr. Rhinebeck, for the tip on the 3D printed Tazer mount and OBDII dust cover. Those two items really helped clean up and protect things behind the dash.

@LSJKU
Good to hear the info I posted helped you...

The ideal set-up is to have a set-up that you can very very easily bring into play when you are out on the trail, on a busy, dark Interstate Highway late at night, etc..

IF you have a dedicated security gateway bypass module (ECRI or ZAutomotive branded) in place 24/7, 365 and you throw a code, you go into limp mode, etc........ that you can in seconds, without any drama... without having to crawl under and hook up clunky, iffy, el-cheapo 12+8 Chrysler cables square things away/clear the code.. All you need to do if you have the dedicated security gateway bypass module is to plug in the BT Scan Tool into the ODBDll port and have at it. Again, No having to crawl under the dash to hook up 12+8 Chrysler cables , yada yada.

Yes, a dedicated security gateway bypass module will cost you $59 and 12+8 Chrysler cables costs half that... but you are far better off with the module and it is easily re-sellable someday whereas the 24/8's will be had to sell and recoop your $. Also.... 12+8's tend to fail over time with bending. Not so with the module.

Trivia: The guy in Poland that brings us JSCAN uses a dedicated security gateway bypass module, not 12+8's. He told me he made his own dedicated security gateway bypass module. He encouraged me to go with a dedicated module.

My goal is a bit of comfort and convenience for the misses. It's her JL, she drives it a couple hundred miles a month, usually not after dark and never off road.

She wanted one when she turned 16 and her parents wisely said no. I bought her a new JK in 2011. I sold it a year later with 2500 miles on it and we worked on paying off the mortgage. Now that we are retired, she will probably keep this one for many years.

 

[THAW]

Please note: Tazers and ECRIs are not "security gateway" modules as some are writing in shorthand; they are security gateway bypass modules.

They do not provide security. While connected, they bypass the factory Security Gateway, removing that security layer.

More specifically, bypass modules (and cables) allow CAN Bus traffic to flow freely between the telematics/radio/OBD-II and vehicle control ECUs; the factory Security Gateway normally filters that traffic to block "public" access to vehicle control systems. Bypassing the security gateway is what allows OBD-II devices to make changes to settings in various vehicle ECUs.

Please consider, "when in Rome" putting the tailgate handle on proximity control for Misses as well. This isn't to say Geo @BMCGC that you can't add it later, deference to your watching your outflow of cash over time right now.

Of course you know her use case and I don't, but IMHO 2 of the most useful reasons to have proximity locks for the better half (I don't mean to sound sexist, plenty of young ladies could probably kick my ass) are so that she doesn't need to reach for her keys when entering the vehicle and to load packages in the back. Again: no sexism intended on the latter: yours truly does the food shopping for the fam.

I do know that within the entertainment system controls that you con configure which doors open when you press the fob once and I think this transfers over to proximity lock functionality. My point being here that if safety at all is motivating this mod, consider configuring the vehicle additionally so that only her door opens when actuating either the fob once, or the soon to be configured driver's door handle.

I don't know why @Rhinebeck01 holds a belief that taking the 12+8 cable route is an ill advised over a security gateway, particularly for your use case. In fairness he may have reasons but I couldn't find much on the forum that bashed this approach, which again I and countless others successfully used, particularly since your Jscan needs are very limited (at least at this time.) Of course as you learn what the tool can do there may be things I'm unaware that don't work, or work well with a 12+8 cable but Piotr Bialik, it's Polish inventor https://jscan.net/fca-security-gateway-module-basic-info-and-location/ I hope would remove suggestion to hook up using this cable from his website if it presented issues, much as its reported that he ops for a security gateway instead. I think I'll email and ask him.

Having that security gateway bypass module (yes, @THAW is right) instead will allow you quick plug in an ODB2 adapter into port, whereas the 12+8 will find you reaching under the steering wheel. But IMHO the true life saver for either approach is the SGW extension cord and with it, either approach is easy for the casual driveway tinkerer like you. Something tells me that the Misses isn't pulling off the road, much less you (or me) because proximity locks has to be reset (after a visit to the dealer.) If you truly have mobility issues or are regularly using Jscan though then I agree that the dedicated security gateway is the way to go.

If you buy such a 12+8 cable on Amazon with good reviews I think it highly likely that it will physically work. What I wonder is if a perfectly fine 12+8 cable still presents limitations here.

Lord knows that I, and many others like me have in hindsight bought cheaper JL products only to have to rebuy a more expensive better one that had I known I would have subjected myself to "buy once, cry once." I'd look at the features a JL Tazer might give you if I were you, along with your bank balance, https://www.zautomotive.com/products/z_tzr_jlm https://www.zautomotive.com/products/z_tzr_jll and decide, if you want to go the security gateway bypass module route, if these features justify to you, its cost over an ECRI.

 

[AndySpill]

I spoke with Jscan earlier today by email. I think Piotr Bialik, its inventor answered, but in fairness the answer wasn't signed so I can't be sure. His firm is small. He may (or may not) be the only one at it.

Anyway, not that it's been said otherwise, but according to Jscan there is no less functionality when using it with 12+8 cables versus a security gateway bypass device. As stated prior, the latter may be slightly easier and slightly more costly, or even in the case of Z Automotive's offerings, provide additional functionality, and can't speak to the quality of every FCA 12+8 cable out there. Mine's in as good shape as the day I got it years ago but in fairness I'm not using Jscan but to reset proximity locks when the dealer "blows them out" after a service visit. Fairness would also find me saying that many are happy with the ECRI device too.

I suspect most of you don't use Jscan that often either to make 12+8 cable wear or installation harder much a factor: the real benefit here lying in use an SGW extension regardless of direction taken.

I think which way to go here may be a little like the argument for @Redline Tuning's hood struts or @Genesis Offroad's non-relocation kit offerings. Both make excellent products but are best for the owner, respectively, popping their hood frequently or going offroad.

(Disclaimer: I own a 12+8 cable acquired before, and now rendered obsolete by my Z Automotive JL Tazer mini.)
