will the V2 work as a J2534 Pass Through to allow acdelcotds.com CAN bus programming?

Before I go an buy the ACDelcotds.com subscription...does anyone know if the EFILive V2 will act as the Pass Through interface for the laptop-web based GM programming update service? The software is Tech II emulator.

I'm assuming I can update my truck's HMI or Radio via the CAN bus and the Tech II emulator software, but I need a J2534 compliant pass through device.

I'm simply trying to add backup camera programming for a 2015 Silverado with IO4 (and no backup camera).

Or better yet, can EFILive tuning software make changes to body modules and radio and or HMI modules?

Thanks, Karl Ellwein

Hi Karl,

No, it will not.

Thanks for the quick reply.

Hello Karl,

As a caveat, I primarily work with Hot Rods or custom vehicles. From time to time I will work with an OEM vehicle (usually as a courtesy to a long-term customer) that requires a programming update of some sort from GM. I have done wheel / tire upgrades, radio/nav/connectivity systems, cruise control, etc.

If whatever you wish to do comes as a kit from Chevrolet Accessories (and you purchase this kit), you will have fewer issues with getting GM to update the programming.

As an example, I have added cruise control to a Chev Cruze on several occasions. The "kit" from Chevrolet Accessories comes with an authorization number to have the programming updated (BCM and IPC programming need to be updated). If you have an authorization number, the process if reasonably straight forward. If you don't have an authorization number, it can be a real pain, and will depend greatly on the knowledge of the person who answers the phone when you call to get the programming updated.

GM dealers can call the GM Techline directly. If you use ACDelco TDS, then you must call ACDelco customer service for programming updates, who will put you on hold while they in turn call the GM Techline.

I have never done a rearview camera upgrade on a new pickup using GM components, so I don't know how difficult this may be, or what potential issues may arise.

It may end up being easier to install a rear view camera kit from the aftermarket (like Rostra).


Best regards,
Taz

The general public can't call GM Techline right? Nor get their TIS subscription via that? I've wondered if the dealers are subjected to the same level of restrictions that TDS customers are.

Hello Ross,

The answers seem to depend on where you are located, and who you know.

In the USA, I believe GM dealers still do their own programming - and therefore have a GM SPS account. In Canada (at least in Ontario anyway) GM dealers no longer do their own programming - this function has been contracted to another business entity.

Non-GM businesses must deal with ACDelco (at least here anyway) for programming services and subscriptions.

If you have access to a GM SPS account (login) there is NO restriction on programming - you can still bench program anything and everything. If you have an ACDelco TDS account (login) then programming restrictions are active.

If you call the GM Techline they will immediate ask for your account - if you have an ACDelco account, you will be referred to the ACDelco customer service line. When you call the ACDelco customer service line to get programming updates applied, you will be on hold for a bit while they then call the GM Techline to get the programming changes activated.


Cheers,
Taz

I live in Ontario Canada and work at a GM dealer. I replace and program all my own modules. The modules come blank and must have the vin programmed into them. And when I add an accessory like cruise control or remote start we have to call tech line as well, and give them an authorization code.

What kind of programming restrictions does ACDelco have vs SPS?

Nice to know that some dealerships in Ontario have maintained in house expertise. Many use York Electric for programming work.

As of January 2015, ACDelco TDS will not allow offboard programming of 2010+ modules. Kind of funny when you think about it - GM use to market an offboard programming adapter.

We order radios and on star modules and clusters from york. But we program them when they get here. Any electronic upgrades that a customer wants such as nav, or backup camera they will come down and change parts and program for us.

I have a great relationship with my local GM dealer - and always try and purchase GM parts from them, rather than importing these. The dollar was trading at 68 cents US today - making purchasing locally that much more important to managing costs. I have no use for York Electric.

GMCDenali, have you added backup cameras to customer truck/cars? (such as in my case where I have a 2015 Silverado LT with 4.5" screen and no camera and desire to add a backup camera) . I'm just wondering if so, then do you simply update the radio module with programming for a VIN that came with the camera or is the programming available using my VIN?

EFILive subject mater related to this...I think it would be awesome if the EFILive V2 could work as a pass through J2534 device too which would allow me to subscribe to the AC Delco tech line and upgrade customers to remote start and back up cameras and such.

From the posts between Gmcdenali and myself, I came to understand that "add ons" to vehicles were done by York Electric, while maintenance (and programming) of existing components were done by GM Technicians.

In an OEM vehicle, using SPS, you can only program with the VIN for that vehicle. GM would have to update the vehicle's programming (based on the VIN) to activate the desired features. This is where an authorization code from a GM kit will expedite getting the vehicle's programming updated.

Hi Taz, thanks for the reply and info.
Just pulling this thread a little further, I see that from the GM Tech line and using my VIN there is HMI and Radio software for backup camera, (even though the factory did not install it). So the "CVN" is 0001EB5 and part number is 23159645 (for example). I am now assuming if my dealer flashed that CVN or part number then that would tell my radio or HMI to toggle to the video input during shifter in reverse signal.

EFILive guys...have you thought of expanding to get into the various control modules such as the HMI so that we can custom tune them, (put our company logo on the Radio video screen for example)? (and turning on camera input functions or navigation).

The GM Techline is a telephone number, that connects you to a service representative. I think you are referring to the VIN / CVN database from the TIS2WEB service website.

However the vehicle is currently programmed, is the only way that a GM dealer can program it. There is often optional programming available, but this requires the staff at the GM Techline to update or "release" this programming.

Not all hardware "updates" require a programming change. The rearview camera may or may not require a programming change - have never done one.

It is highly doubtful the EFILive will ever offer a J2534 pass through device - there are many of these already on the market.

Taz: I stand corrected. I am referring to the TIS2WEB service VIN / CVN database....not the GM Techline.

Let me ask another non-EFILIVE related question. If there are not any optional upgrade equipment software/firmware programming available via GM dealer then how do the aftermarket companies upgrade? That is basically what I want to do...change programming in my 2015 Silverado HMI and Radio.

Aftermarket companies find "work-around" solutions regarding late model vehicles. Take a look at the Rostra website. For late model GM Trucks they offer an OEM looking backup camera system. The camera is in the tailgate release handle, and they replace the OEM windshield mounted rearview mirror with one that displays the input from the camera. They also offer a cruise control system that inserts in-line with the APP (gas pedal) - I would never use one of these - but that was their work-around.

Yes that and on anything outside of the USA they have a lot of checks before it can be programmed. Eg, you can't return a Holden to stock, it will not allow a write if the segment numbers match up to what it is about to download. Makes me wonder how Holden dealers do this? Korean and Opel cars forget it, they all need TIS approval numbers.....how does a non GM dealer get that? Crazy stuff.

While I'm complaining about TIS, the service area is rubbish too. GM have really dropped the ball on this. We also subscribe to Chrysler/Dodge Tech Authority, the service data area on that website is amazing, blows GM out of the water with the best wiring diagrams and layout I've ever seen.

You are right, plenty of cheapish options on the market and it isn't as easy as you might think. Pretty sure it is some sort of scripting type language that is used, I don't think we'd have room left in the V2 flash to implement it.

I don't know ant dealers that are bench flashing anymore. Should be the other way around but I am guessing GM is keeping programming out of the parts supplier's hand by doing this.

FWIW, when I added the backup camera to my 2010 CTS, I just got a 3 day subscription and reprogrammed the radio, selecting the calibration that included the backup camera. Easy as pie. The camera was not an option in 2010, but the same radio was used until 2013, so the programming is available.

Thanks for at least considering making V2 available as a J2534 pass through...and editor of CAN controllers. Editing of the HMI and radio and dash display would add a new market of customers for me and for you. No need to go to GM for the updates and the ability to give customers custom logos on their radio display and or custom parameters on the dash and other things like window roll up from key fob etc.

There is one company that sends a small dongle that plugs into the ALDL and auto tunes the CAN HMI or Radio module (as if the factory was doing it). It is fascinating!

No work-around. Elegant plug and play and Factory fresh.

Maybe one day EFILive can add select or limited CAN module editing? :)

Cougar281 thanks for that info. Please tell me...what passthru device did you use (Tech2?) and how did you select the programming? Did you insert a 2013 CTS VIN in the lookup?
I am contemplating going this route but I need to buy a J2534 passthru and then the $55 3 day subscription.

I used my Tech2 w/CANDi module and no, didn't have to use a different VIN. I just selected the radio for reprogramming and when it asked what calibration to flash, I told it the one with the camera. I'm not sure of the current address, but calid.GM.com used to allow you to enter your VIN and see what calibrations are options for the modules under your VIN.

It was similar when I reprogrammed the original headunit in my truck from 'premium' to LUX for the LUX amplifier.

Thank you very much for that info. It validates what I was thinking. I did look up the latest calibrations and options at www.calid.gm.com and my VIN does have radio and backup camera tune and HMI and backup camera tune. Very helpful info sir. thanks. Karl

not exactly EFILive related but here is the info (if anyone is interested) as to how to have the GM programming available for your vehicle to do things like activate the back up camera, (if it was not originally equipped).
As someone mentioned in this thread, you basically call ACDelcoTDS and ask for authorization. They put you on hold and they talk to GM. Then even though the backup camera was not purchased as part of an official GM accessories package they still make the HMI module reporgamming available. The AC Delco guy on the phone said it would cost an additional $50 (as well as the SPS subscription). The SPS programming was quick and easy. I selected the HMI programming and it flashed the HMI in about 5 seconds. So apparently they authorized my account to have that programming. Otherwise it would not work as I tried to do this last week and it only recognized that my HMI was up-to-date and it would not program it.
Karl Ellwein

My apologies ... when I described the process earlier in this thread, I neglected to mention that unless you have a programming authorization code (which is included with some Chevrolet Accessories kits), there is a $50 fee to update / release the programming.

Nicely done ...

Thanks, good to know.

Is this a one-time deal (i.e. do you have to do this each time you want to flash a unit...?)...?

Thanks Taz and joecar, Taz...very much thanks for your advise. joecar, it was a one time deal and it seems that if I were to do this again for another car they would require me to get permission again.
I'm glad it worked though. It was quick and easy after having permission.
