Reversing camera problem - would an obd11 fix it?

[Crippso]

Hi all
A garage has recently fitted a pioneer head unit and WiFi reversing camera to our 2016 T6. They really struggled to get camera working reliably. Sometimes the image is ok. Sometimes it drops out or goes noisy, with image repeated three times on screen. Accelerating makes it worse. They say they tried to hard wire the video signal and no change (so it's not the WiFi link between camera and head unit).

Doing some reading on line it sounds like it could be due to PWM on the power to reversing light (where the camera gets it's power from). They fitted a voltage stabiliser/filter but still no good.

Google ai suggested using obd11 pro to turn off pwm on reverse signal. I wondered if anyone has experience of that and knows if it's possible, and if it can resolve the camera imagine issue? If so, I'll possibly invest in one. I have a carista evo but couldn't see options to turn off the pwm

Thanks
Stuart

radio revering cams are pants unfortunately.

you will run around in circles trying to get that working correctly.

best option is to bit the bullet and get a hard wired one,

if you have a full conversion - yun can run the cable under the van to the engine bay or to the seats - then to the radio.

Agree that hardwiring is much more reliable, but it does sound like the PWM on the reverse feed is also an issue. Rather than try and code out the PWM, I would try a specific PWM filter or a relay for the camera power feed.
If you do want to code out the bulb failure for the reverse lights I suspect you would probably need VCDS rather than OBDeleven, but don't have OBDelevn to confirm sorry. Others can probablt advise.

Need to do something like:

1. Go to 09-Cent. Elect..
2. Select Security Access - 16 and enter code
3. Select Coding - 07 and open Long Coding Helper.
4. Navigate through the bytes to locate rear light diagnostics (typically Byte 19 for T6.1, though it may vary, look for "Lamp Diagnostics" or "Cold Monitoring" for reversing lights).
5. Untick the box related to reverse light diagnostics.
