Suspension Wiring Connectors

[Riviot]

I recently received the dreaded Service Suspension Soon / perimeter sensor warnings. After a car wash, they would flash on for like 3 seconds, turn off, then repeat a few times during the ride home. Now they're staying on after about the third flash. A sleep cycle clears it but it inevitably returned. Luckily, there is no turtle mode with it, which made me suspect wiring and not true suspension issues.

Having dove into the other SSS posts, I couldn't find any pictures or description of the connectors to check. So naturally, this riviot climbed under a 7000lb truck showing suspension errors and started poking around. ??‍?

Once I figured out how to remove them gently, I tested my theory by asking my wife to check the driver display (no issues), I pulled a plug (errors popped!), and then reseated (errors gone).

Each strut has 3 connectors, with one of the rear further up and harder to reach. All of mine were caked in dry mud, pine needles, and all other sorts of detritus. I pulled them all, cleaned, and went for a drive to do errands. Sure enough it returned.

Coming home with the error, I asked the wife to monitor the driver display while I jiggled each connector. Culprit: Passenger Front, #2. I popped and reseated, no issues, so I covered it with electrical tape and tried to rig it to stay secure. ??

That’s what you get for washing your truck

Interesting. Sounds like you found the source of this issue. I wonder if it's the female or male side of the connection that is the source of the issue seems like the connection is not secured properly?

I would guess male end, the connector within didn't seem all that strong. If I had full access to parts, I'd get a new harness and probably just that one sensor.

Time will tell if my fiddling alone fixed it, we've got 1200 miles this week to test it! The irony is all the bumpy off-road I did last weekend, and there were zero issues.

@Riviot thanks for this!

I would also recommend putting the vehicle in the highest off-road highet and put it in Tire Change Mode for extra safety against unwanted changes in ride height while you're under it to check these.

Did you just trial and error unplugging each harness until the air went away? I have the same issue only when it rains.

Turns out I had a chafed starboard wiring harness. The original gen1 harnesses didn't have a lot of give, and mine got worn out somewhere along the line, exposing the wire and allowing water to make contact. They replaced the entire wiring harness, which took a very long time to diagnose and replace. I had to go in and remove my gear tunnel slides so they could access the harness as it runs along the inside there.
