2003 Santa Fe GLS 120K mi. 2wd, 2.7L, AT.

Been having for some time an intermittent problem where the air bag light will come on and not clear. I can clear it sometimes by removing the neg. batt. term. and letting it sit for a few minutes. The "air bag" light always seems to come on when someone sits in the passenger seat. The dealer reported a trouble code of "B1382-- PSAB harness improper pin tension" They said that they re-seated a connector and it was good to go. Now the "air bag" light is on again. Does the description refer to the pin tension in a connector? which connector does it refer to and can I just tighten up the female part of the connector such that the male pin makes better contact? Is it the yellow connector under the seat?

any ideas?

Hi Bo.
Yes, many airbag errors seem to point to bad connections of the connectors underneath the seats.
An electrical error cannot be related to a mechanical pin tention, but would certainly indicate a wrong pin tension, so voltage.
This can point to a bad contact, open contact or short circuit.
Often it points to a bad contact between pin and female connectors.
So you might need to check loose connector or maybe corroded.
Sometimes WD40 does the trick.

Good luck,
Paul

1382 means there is a resistance issue with the PSAB circuit


B1382 Side airbag front-Passenger resistance too high (open circuit) somewhere between PSAB and SRSCM

"Loose pins" is not a monitored code specific thing.. SRSCM is looking at high resistance, low resistance, short to ground, short to battery... look at the laundry list of applicable codes to SRS..

I have my own way of testing the circuit, I use GDS in the DTC screen, create short and watch "low resist"code pop up, open the circuit, see low change to History, and now high resist marked as active,, well now I know harness between component plug to SRSCM is in order..

majority of time, the movement of pigtail off connector moves the terminals around over time, and now you essentially have a 1/2" dowel in a 3/4" hole for pin fit... looks like good cause for high resistance (open circuit to me)... I take a tiny pick and close the opening of the female end to reduce size of opening so the male pin fits tighter in the hole (excuse the porn please).. hence the better contact.. prior to re-assemble of connector, wrap the end of conduit with electric tape to up onto the end of yellow connector to provide support.. plu it together.. snap it into the black holder under seat...

NOW.. use a couple zip strip to secure harnass to seat bottom.. secure the harness (floor side) approx 2 inch from connector to seat botom/frame so that when harness move with seat movement, it actual flex point is at the zip strip, and not at the wires into/at the connector where the flexing wiggles the pins to open the circuit again.. do same for opposite side of connector for PSAB pigtail into seat

In the end, DO NOT PUT JUNK UNDER THE 2 FRONT SEAT !!!

Thank you paul/sbr.

This confirms what I originally posted. That I can tighten up the female end to make the male end fit tighter. I'd rather play with the female side if you know what I mean.

And knowing that there are connectors residing under them, I have never made a habit of putting anything under the 2 front seats besides the occasional dunkin donuts wrapper.....

thanks again guys.

no joy. I removed and checked the yellow connector under the pass. seat. Only 2 wires/pins. They are actually bayonet type flat "pins". The pins look ok. In good position and not distorted/pushed back. I cycled the connector to scrub the pins and then re-assembled. and secured. air bag light still on. what is the resistance that the system sees at that connector? is it possible for me to connect a dummy resistive load so that the system thinks it sees the passenger side SRS? I do electrical/electronic work and have a DVM. Can I check the resistance of the seat SRS safely without setting the bag off?

What are the "next steps"

Best advice I have read all day!

To add a little levity and, hopefully, bring a smile while you're being traumatized by all of this: "My airbag light illuminates every time the wife gets in the car." After 42 years, I'm still learning to accept it.

If this is definitely a contact issue, or lack of contact (hi res) in the 2 wire yellow connector under the passenger seat what about (I know it' a drastic step) just cutting off the connectors and soldering/heatshrinking the wires together for a more permanent connection??

What's the downside, besides the obvious no connector thing??

Not quit sure what SBR was talking about, the connector or maybe the sensor unit itself?
I have no idea what the sensor actually is build of.
I read some thread in the past about a problem with airbag sensor they had to replace the whole seat for it.
But for a problem with connectors, I'm also sometimes simply replacing a suspected connector for a permanent or semi-permanent connection, the latter being a screw in connector. That provides certainty in connection.
Downside would be if you had the need of taking the seat out (maybe inspecting the sensor) you needed to cut the wires again, but I think that wouldn't be that difficult.
Good luck,
Paul
