DIY: [How-To:] Racing Seat airbag light fix

DeliriousClam

I just bought a pack of 50. I still need to test them but if they check out I'll mail you some

How are you testing the resistors you have in place?

Using the terminals on the connector will give you odd readings that will cause you to think the resistors are bad. Had the same issue when I did mine a few years ago.

First I already had my connectors done up and heat wrapped. I then put the leads on the exposed wire from resistor to heat wrapped. The reading was .8-.9. Granted I had already tried testing both connectors with resistors plugged in and the original weight sensor plugged into its connector. I also went thru the reset procedure. I also tried using the leads within the connector and same reading .8-.9 So maybe these blew?


I tested with just the resistor, new one out of package and put one lead on each side and was reading 5.5. How else do you test them?

I ordered some new ones. These were a bit more expensive as they were 4$ for 10 as last ones were like 4$ for 100.

What gomer_110 is trying to tell you is that you can't check the resistor in-circuit. You will need to disconnect one end of the resistor from the sensor circuit to get a good reading.

To pick a nit: It's not the connector that is the problem (unless you have a bad connector), it's what's hooked up to the connector (seat sensor).

The seat sensor is an entirely separate item. It's NOT connected to the same harness as the airbag and therefore has no effect on the resistance reading.

ah. I''m getting two convos mixed up. Sorry about that.

I am about to tear out my dash to remove the bulb for this air bag. I have tried 4 different types of resistors. Testing on resistor leads on each end not connected and voltmeter on 200 OHM setting(lowest) it reads 5.4-5.5. Was thinking it should be 4.7. Idk. Each time I did the reset trick and this thing never works. I have the weight sensor plugged in from passenger seat and both clips in for airbags with the following resistors.

Any ideas?

disconnect + on battery and wait 5 minutes to reconnect. Worth a shot

May we know why the positive and not the negative? I always disconnect the negative to reset.

Actually the way I've always done resets is disconnecting both and touching the cables together. ALWAYS reset everything.

A direct short like that can cause problems (the capacitors discharge too fast). Pressing on the brake pedal (or placing a fairly high resistance load between the terminals) will limit the amount of current. Granted, it's not a big problem with most modern electronics, but why take a chance?

Doesn't matter. No need to wait 5 minutes - just press on the brake pedal for a second or two.

Took four hours but mine are in and everything is functional including the weight sensor. Don't know maybe I just got lucky

Any chance you can include a link to where you bought them or can you tell me what voltmeter reading you have on a spare resistor?

If you have extras, maybe you could send me 2?

Searching online it says it should show 4.7 not 5.5.

Can someone please post a link to resistors you can buy online that you have used and are working?
