ACC (Adaptive Cruise) Retrofit >> Underway, PSA

[rhill2901]

That’s a good possibility. When I query the module in Jscan,, I can see the previous vin and the current vin is the same and it is the vin of the donor vehicle. I haven’t progressed to the point of getting it aligned yet, so I haven’t confirmed what you say. When I restore all the options back to the original prior to installing the dasm, I still get dynamic cruise and adaptive cruise configuration faults. Disconnecting the module is the only way to clear those faults. So it is highly likely you are correct. The cost of the radar camera new is obscenely high so I might just put this retrofit on the back burner for a while.

I doubt you’ll be able to use a used DASM (radar camera). That’s how it is with doing this on a Ram, and it’s basically the same DASM. The original VIN and current VIN stored in the DASM are locked, and unlike most other used modules, it will not pick up the VIN of the next vehicle it’s installed on. This stores a configuration mismatch in the DASM, and it can’t be calibrated. I’ve tried everything I could on a used DASM, but even CDA 6 doesn’t even give the option to write to the VIN counter.

I am not familiar with CDA 6, I assume this is a subscription-less option to replace WiTech? The WiTech and Stellantis subscriptions are insanely expensive (~$3k/year) for someone not using the device for service work. Do you know if CDA 6 will do everything the Stellantis/witech software does?

Unfortunately, you definitely won’t be able to use it. If it was going to work, it would have picked up your VIN as the current VIN after the first time you put the ignition in run.

CDA 6 (Chrysler diagnostic app) is what the engineers use that dealers don’t (usually) have access to. The problem is, it is live online only, so the only way to get it is a cracked version used with a micropod clone. Depending on who you get it from, it varies on how many/which ENG files are included. You won’t have access to any new flashes that come out. Since this is where Jscan and AlfaOBD pull all their info from, it’s basically a glorified version of those, with a few extra capabilities in extended diagnostics. But, it’s another good tool to have in the arsenal.

I"m considering trying something like this.

Reminds, me of recoding my Audi S8 ECU when I swapped a manual in it. Down the wormhole, you go.

$180 used, $1500 new, i think i'll tinker for a while

anyone know if you can separate out the ACC system to just the high beam control module?

Would love to have auto high beam with out all the other nanny stuff.

The auto high beam system uses the ACC camera and control module. The acc camera & control module wont function without the ABS module & controller....

 

[rhill2901]

What if... you changed the submenu setting from ACC with Stop to just ACC? Will the ACC control module still be looking for the abs module & controller?

Yes, that’s just the type of ACC used on the vehicle. And actually, on the gladiators, if you have a manual transmission, you can’t use the ACC with stop configuration, you have to use the ACC setting.

bummer, i was hoping there was just a photometric sensor that was added to the camera board that had some pin outs you could tap to.

Yeah, unfortunately like @DC3 was saying, you have to be all in. The DASM needs to be calibrated to function at all, and it won’t calibrate in the first place if the rest of the correct components and configuration aren’t in place.

That should definitely do it.
Here’s the issue when using normal means of trying to change the VIN:
Here, you can see that the VIN is locked, and in the “write” column, there is no option to write to the VIN odometer:

And here is the reason the CPU prevents the VIN from being written to the eeprom, because these values would need to be reset to 0, but since there no write function…

Here it shows that the VIN CAN be written, but since it’s locked, it fails to write:

Taking apart the acc module:

1. Remove the 4 outside screws and run a blade around the cover to cut through the silicon.
2. The cover comes off and exposes the radar antenna. Take those 4screws out and gently pry the board from the module. The backside has electronics, most likely fir the radar high frequency circuitry.
3. Remove the metal shielding cover, which exposes additional circuity and the 2 screws holding the camera in.
4. Remove the screws and the camera comes right out.
5. Now I’m stuck, still haven’t seen the eeprom. Suspect it behind this board. The board won’t come out because the connector on the backside of module is soldered directly to this board. I’ll need to get desoldering wick to continue….
