Volvo Xc40 ultimate 2023 Led to Pixel Led retrofit guidance

[nismoboy]

Thankyou to the creators of the software and to this forum .
I've had the luck of getting a front end damaged volvo xc40 recharge ultimate. have purchased a front end that has Pixel Led headlights . Ive inspected the previous headlamps LED only and found them to have the same pinout for the connector which is great. From what i can tell the vehicle comes with the radar and Camera on the Windshield as well as on the Nose of the Grill .
So in short this should work out .
Now the real questions come .
By default is it possible to code the headlamps using Orbit to the vehicle?
If i do this will the pixel LED still turn on and remain focused ahead as per the factory config on the Headlight control module ? I know these functions are driven by canbus messages and not sure what are the enable commands for park headlight and bright, and if they are universal across the head light control modules LED and LED pixel ? Possibly some canbus snooping might be required .
Following this would be the logical steps of enabling the functions ( not sure where either in the Body control or Vehicle control ) that will provide the Led pixel functions of active sweeping around corners and dipping for oncoming vehicles etc.
Is there any way i can verify this information from those that are more experienced and understand the tech in more detail and what controls which functions where ?
I still have a way to go to reset the SRS unit but i do have a ENET cable from some BMW work i carried out for a friend so a few steps ahead thankfully . Will soon grab a license for the software and get going . Thanks in Advance ...

SRS cannot be reset via cable. Either new SRS or send to SRS module to specialized company that will clear memory on bench. Following instructions carefully when removing SRS. Make sure battery has been disconnected for a long time.

For light changes which means HCM change see working with headlights and HCM in How To Guides section.

Hello everyone

I'm planning a standard LED to Pixel LED headlight retrofit on a CMA platform car and wanted to share my research so far, ask some questions, and hopefully contribute to the community as this progresses.

---

**My Car:**
- 2023 Volvo C40 Recharge Ultimate
- CMA platform, Android/iCup infotainment
- Built WITHOUT pixel headlights (Thailand market — pixel option was removed during the chip shortage and never came back for my market)
- Standard LED headlights currently installed
- Car has front radar and windshield camera (for driver assist features)

**My Goal:**
Full pixel LED headlight retrofit with adaptive driving beam (ADB) functionality enabled via OrBit.

---

**What I've Researched So Far:**

I've spent considerable time going through this forum, SwedeSpeed, XC40 Forum, and the Polestar Forum. Here's what I've pieced together:

**1. What Works on SPA (Reference)**
- Power6 successfully completed non-bendy LED to bendy LED swap on his 2019 S60
- Key lesson: factory non-bendy HCMs (stamped "MID") physically won't support bendy lights — need "HIGH" stamped HCMs
- The diagnostic part number and software are the same for bendy/non-bendy HCMs to VIDA
- Best approach: buy headlights WITH HCMs attached from donor car to avoid software/pairing issues
- OrBit can handle side assignment, software loading, and headlight learning if parts are sourced separately

**2. Pixel Activation via OrBit on CMA (Proven)**
- Multiple XC40 Recharge and Polestar 2 owners have successfully enabled pixel ADB by changing:
- Parameter 106 (Headlight Type) — change to pixel variant value
- Parameter 109 (Active High Beam) — change to "06 With AHB3 (Adaptive) Pixel Light"
- This works on cars that ALREADY HAVE pixel hardware installed
- No infotainment menu changes needed — pixel function is controlled by headlight stalk (Auto High Beam), confirmed working when dash icon turns blue

**My Questions for the Community:**

1. Has anyone here completed or attempted a physical standard LED → pixel LED headlight swap on any CMA car? Even partial progress would be valuable to know about.

2. Do OrBit's HCM tools (ECU Tools — side assignment, software flash, headlight learning) fully work on CMA pixel HCMs? I've seen that post-2021 HCMs have limited third-party support.

3. If I source complete pixel headlight assemblies WITH HCMs attached from a wrecked C40 or XC40, is the process: physical swap → OrBit CEM config change (106 + 109) → done? Or are there additional CMA-specific steps?

4. The 2 extra pins on the pixel small connector — does anyone know what signals they carry? CAN bus lines for pixel matrix control? Or something else?

5. Is there a MID vs HIGH hardware distinction on CMA HCMs like there is on SPA? How can I identify the pixel-capable variant?

6. Would a pixel HCM originally from a Polestar 2 work on a C40 after OrBit reconfiguration? Or must it be from the same model family?

7. If I have to buy pixel headlights and HCMs separately (since eBay sellers almost always strip them apart), what do I need to watch out for?
- Are there specific part numbers I should look for to ensure the HCM is the pixel-capable variant and not the standard LED variant?
- Does the HCM come pre-loaded with software that works for pixel headlights, or are there different software versions for standard LED vs pixel?
- Does it matter which model (C40, XC40, Polestar 2) the HCM originally came from, or is the software universal across CMA?
- Does the HCM need to be re-paired/learned to the new headlight assembly, or will any pixel HCM work with any pixel headlight unit?
- Is there any marking or label on the HCM itself that identifies it as pixel vs standard?

Thanks in advance!
