Bench to Bucket Seat Swap

Okay so a couple more questions to follow up, I actually did this swap last night haha.

1. The airbag codes that I am getting are: B1801 and B1650. These were actually present before my swap, so I'm assuming that B1801 is a clock spring issue, yeah?

2. The fact that B1650 was present at one point, and still is, just makes me assume that calibration is off. Because as it stands now, the passenger seat does detect weight in it, the airbag ON light illuminates when someone is sitting in the seat, and the flashing no seatbelt light comes on.

3. You mentioned not swapping over your bladder sensor, how do you get the airbag code to not trip? I currently have mine wired and am going to try and recalibrate it, but if that does not work, I obviously need to go a different route.

4. There was a Seat Position Sensor on both sides, so but I mounted that and think it's working fine, no codes.

 

For #2 and #3, you have to emulate passenger weight. I posted up how to make the switch in another post here that outputs two different values. one value for no passenger and one value for a ~160 lb passenger sitting in the seat.

If the occupant ECU that is originally under the passenger side of the bench can't detect that there is a bladder sensor present, then you will get codes. The switch will fool that occupant ECU into thinking all is well and the best part is you have control if the dash airbag is on or off regardless if there is weight in the seat or not. Great for those that have small children or a dog riding. You just have to remember to turn it on if you have an adult passenger riding.

As for #1, I never saw that code on my truck so I am going to guess that is a completely unrelated issue.

Surprisingly I probably spent the most amount of time getting the seat belts to cooperate and not trip codes. Of course I could have reused the original seat belts but the inner buckles for the bench have an odd twist in them that interfered with my new aftermarket buckets and console so I just removed all the original seatbelt stuff went all new OEM as if I had OEM buckets. I don't regret it at all.

 

Okay so ironically, I went outside and cleared the code history, and the Seat Occupancy code did not come back. Sat in passenger seat, airbag turns on and seatbelt light flashes, and stops when belt is plugged in. We're in the clear!

Once I moved the wheel B1801 came back so for sure seems to be clock spring. Unrelated, but a good problem to have that it's not seat related.

As for the seatbelt buckles, of course mine have that twist as well. I wanna use the same receptors because there's no wiring mods needed for the harness. Could you explain more of what you did?

In my situation, I could bolt on the bucket seat buckles but there's two problems, the connectors are not the same for wiring, and two the seatbelt latches are too large. That can be grinded, but I still have the wiring mismatch.
