I'm in work tomorrow (sorting out a D3!) so I'll do a bit more prodding - the venturecam terminal voltage was stable, the charge level showed as ~75% when docked.

Sorry mate, didn't get chance, a couple of diag jobs (which are not to be booked in on Saturdays) were, well, booked in...
I'll try again during the week.

BTW, I assume fuse 43 in the CJB is ok and not corroded?

Oh no problem, thanks!!

I think on a 2010 vehicle its fuse 65. That's intact and is shared by the surround cameras which are working fine.

I needed to finish routing the cables for a dashcam so while I was on I swapped the dock for the other one I had (which is from a 2008 vehicle), there's no difference to the operation of the dock / cameras. I also put a pin in the plug for the dock and at the plug I measured just over 14v.

Can only presume that for some reason a 2008 dock is not compatible with a 2010 vehicle?

Cheers

Unless the signalling on MS CAN is different, I can't see why not - I suppose it's possible that the dock isn't getting the 'ignition on' message, that would prevent it working.

That was my reasoning too............

Is there a way of checking what the can hi & lo connections are doing at that plug?

Was watching a video about such things earlier & although it pointed out how you can't be sure that the rest of canbus circuit is good from a resistance check I suppose if I'm only wanting to test that single canbus wire pair then does a resistance check between hi & lo suffice?

Not really, you want to check each leg to ground, but that will only confirm activity, not the content of the data packets. If you can 'scope each line, you should see something like the photo below on the CAN-H line, the CAN-L will be similar but drop down below the baseline.

Click image to enlarge

If not, the voltages should be around +/- 2.5VDC with respect to ground.

To fully test both the CAN & the module, disconnect the CAN lines and test at the cable, then test the dock, there should be CAN voltages / frames at both. Of course, this doesn't check whether the earlier dock can understand the later vehicle frames, just that communication 'can*' take place....


*see what I did there? Wink

Thanks very much (again!) for the info.

Sadly scoping it is beyond what I have the equipment or knowledge for...

When I get a chance I'll get in there & check the votage between the pins & ground.

Before that, although the camera button appeared correctly in the 4x4 info screen I might try removing the camera and dock from the CCF and re-adding (& will try both with the camera in the dock & out (I cant remember for sure which way it was when I added it before)).

At least I'm getting good at taking the passenger side dash apart Wink

Edit to add: I've also emailed GAP, to see if there is anything else in the CCF (apart from 'A venture camera system is fitted' and 'Companion docking station') although I can't see anything and I've seen reports (in this forum) of successful retrofit which mention only those two settings to enable.

PS, At least it wasn't a joke about bean cans! Smile

Right, across the Venturecam, I get 2.95VDC (not docked) across the dock pins with the ignition on, I get pulsed 5 - 11.5VDC
Hope that helps....


Just been checking my cameras again....... one of the two I had with power in them is now too flat to turn on. However. none of them show any voltage at all across the pins on the camera body (& yes, I tested my meter, with an AA battery).

I'll try to find someone in the area with a working cam / docking station and hopefully try their camera in my dock & one of my cameras in theirs.

If that works then I'll take the batteries out and try a circuit as per MikeO's post.

Did you get any chance to measure the CAN voltage?

Not yet, that will need to wait until I have a chance to get the dash taken apart, again Censored

Was thinking before I do so I'd try one of my cameras in another car (if I can find someone in the area with a working venture cam) & hopefully a known working camera in my car.

I've just taken the camera which still turns on apart to check the voltage at the plug on the battery lead and I get 8.7v, so it's not a camera low-battery issue. But, why would it be 0v across the contacts on the back of the camera(s) when you get 2.95v? It's making my head hurt now haha Smile

Maybe because mine had recently been removed from the dock? There is next to no info on how they interact with the dock other than the IR LED - mine works 'occasionally', which I'm putting down to the 2.4GHz band being saturated in towns.

I've just checked again - 2.95Vdc across the charge terminals, which made me check the test points on the PCB, same voltage. Mine was in the dock but not latched, it's possible 'someone' (i.e. the Mrs.) has been playing as it was charged and operable last time - but with a similar charge pad voltage.

Terminal voltage is still pulsing on the charging pins 5-12VDC with the ignition on but engine off.

ETA - the test points are two round copper pads near the battery connector on the PCB, there are also two below the connector for the charge pads

Thank-you very much, again!!

I've just tried the points near the battery connector, 7.85v. The points near the charge pad connector though I get 0 (which figures with the pads themselves being 0). Just to confirm please, you get a voltage on the second set of test points yep?

When I have some time I'll try the camera with recently depleted battery (there must be something left in it) but I suspect that it'll be the same story, as the charge pads showed 0v when it had the juice to turn on. Next step I guess is putting the new battery pack (which has good voltage still) in the third camera (the one with a completely dead battery) & see what the test points show then.

I'm getting the same voltage on both sets of test pads - looks like your PCB has an issue... there is continuity between the -ve pads but a 2VDC differential between the +ve pads which indicates some sort of voltage processing / regulator between the two to me.

ETA - bear in mind it's 'old tech' and capacitors don't last forever - especially on electrically dead circuits.

Yep, certainly looks that way.

Hopefully one of the others will come to life with the new battery pack in, at least then I'll be able to confirm the docking station is working (or not!).
