Passenger Restraint Malfunction

famm3 · 05-11-2017, 09:24 PM

"Fault in passenger restraint system...."

Just got this code out of nowhere. Any idea what could be wrong? I tried searching everywhere and every thread says something different. Anyone can help?

I have the same thing and at this point it has been determined that it is the seat sensor that determines if someone is sitting in the seat. But it may also be the seatbelt tensioner. I will find out for sure when she goes in for the air bag recall.

Is it safe to leave the light on?

Just don't drive 60mph straight into a wall and I think you'll be fine. Eventually you should probably head to your dealer or local mechanic to have it checked out. I don't believe anyone can diagnose it remotely from here. Is it driver or passenger side?

Yea, mine is passenger also. Maybe some one has an answer.

Scan it... It can be multiple things.

Can this just be coded out? The floor mat sensor? But I still want the airbags to deploy

Check the battery cables in the trunk. It may be a loose wire on the positive cable on the side facing towards the front of the car

Yes OP, this is a possibility. Access to the battery is fairly easy. To your question yes, It can be coded out if it's the seat mat sensor but you have to disconnect the sensor wire under the seat and then someone like alex@alpine can code it for you for his advertised price of $60. Or a number of independent shops in your area also I am sure. I have not checked my battery wire as my trunk is loaded right now and I was going to have my service guy check that when I go in for my air bag recall. If not sure where the battery is or which wire to jiggle just use the search tab here or google it. It will definitely come up. Keep us updated on your progress, will definitely help other members if the battery wire jiggle works.

I taped mine down over the battery with a couple layers of electrical tape. Then i bought a battery hold down arm that comes on the 3 series verts that bolts across the top of the battery. I bent the arm a little to provide more pressure down to keep the battery from moving.

I tried to mess with sone wires. Even if it fixes it, will we have to reset the codes? Or will the light go away automatically

My understanding is it will go away. Click your heels three times if it doesn't. That usually does the trick.

Yes you can code it out and the airbag will still be functional.

Anyone know the exact modules to code and to what?

6ixSpd · 05-14-2017, 08:34 AM

Like I said before, SCAN IT. You need to know which exact component of the ABG system is triggering be fault. THEN you can disable it via NCS and clear the faults.

Otherwise you're just guessing with multiple possibilities and wasting your time.

Listen to the man lol!^
If you need help with coding it then ask.

Alright I'll look at the codes and get back to everyone! Thank you

Mine happens to be 93C3 which is the seat mat sensor. Let us know.

famm3 · 05-17-2017, 01:56 PM

Turns out the code is 93B2. Any suggestions on what to do? I went ahead and cleared it and it has not shown up yet.
