Anytime backup troubleshooting

as in pull away from base but still leaving partially in and probing the exposed terminals? Or completely off the base and measure somehow.

 

Off the base, test alone

 

Sorry for the the ignorance. But from what pin to what should I be measuring? I know I should be getting resistance across certain pins but am not savvy enough to know which ones.

 

No biggie, using a 9vDC battery test coil pins (85 & 86) relay should click.

 

I’ll need to find some terminals to wire that up as I don’t have the adapter.

To summarize, if it’s bad I obviously just need a new one. But hypothetically if the relay turns out to be ok what do you think it would be? I personally hope I can just ask for a new relay and go from there.

 

Short jumper wires will do, no need for fancy adaptors.

 

that diagram helped a lot!

86 to 85 yes I am getting a click

 

So now test continuity on the base terminals to the video RCA's.

 

Can u elaborate? Beginner here :-(

Yep understand that much. Just curious where the focus is on now. So back of the JBL unit on the RCA jacks? Prob from back of harness to other end of video cables?

 

Stay with the relay harness RCA's. Base pins to RCA terminal.

 

I’ll need to table this unfortunately. The RCA terminals are buried a bit and taped up. This camera sure is a PITA lol

 

If they are mess up, they'll have to be removed.
Did you ever get to view the front camera on the Head Unit at all?

 

Yes. Front cam works great on the HU when toggled. Rear is just a complete failure.

 

You indicate here that both cameras worked, when swapping connections around. Maybe relay-to-socket connection was poor. Easy to try plugging it back in again and retest?

 

Man I may have mis-spoke but can’t seem to remember. I “think” I might have seen the same issue with no rear cam view except the only difference was the front cam now showed when toggled to rear switch setting. To be honest I’m low on patience to try this again but may try later. My fault for not remembering.

 

Given the relay seems to be ok (which would of basically been the only plug and play fix) I think it’s safe for me to be removing everything minus the camera side to troubleshoot outside the truck.
