seat belt pretensioner question

I'm trying to check if my seat belt pretensioners are still good or i need to change them. I just purchased the truck and i'm not sure if it was in an accident. what is the resistance i should be looking for at the 2 pins coming out of the tensioner? can someone take a known good unit and check? preferably out of a 2004-2006 model year. My airbag code tells the there is something wrong with the system but nothing specific. i don't want to spend the cash if that is not the problem.

You know, I have never seen that question asked. I'll be interested to see the answer myself..

so seems like this is a very unique issue i'm having with my Titan. turn out the abs control module checks for a 2 ohm resistance coming from a working pre-tensioner. All i did was put in a 2 ohm resistor across the connector, meaning i bent a 2 ohm resistor in a U shape and plugged it into the holes where the pretensioning unit would normally go. This cleared the blinking airbag light and now i know which unit is faulty. For some Titan trucks a airbag reset procedure is necessary to eliminate the blinking but mine turned off immediately after the first start. Please make sure to disconnect both battery posts before doing anything with the airbag or abs systems.

Wow, good troubleshooting skills there! I'll have to remember this if I ever have this problem..

[/quote]Dang! nice work there. Like JD, this is the 1st I've ever seen of this issue.
