Is there any way to test the front seat belt pre tensioners with a multimeter to see if they are faulty or ok.

I've just looked in the yellow connector it only as two wires, i'm curious about the brass contacts, do they just connect one wire to the other as a straight forward connection, they look to have a small prong on each that goes to the middle of the plug, does this close to make a short circuit when the other half of the connector is pushed in.

Will it be ok to cut the wires and join them together in case i just have a bad plug causing the srs light to come on.

have u cleared any dtc faults through a suitable diagnostic reader yet

the srs light will not go out until u get it plugged into a reader as its a hard fault

if it reappears then u need to start investigating but need find out what the dtc error codes are first

this is a bad idea digi. not unknown for the voltage from a multimeter to trigger a pre-tensioner or air bag.

cheap multimeters are not so affected, as they only use a couple of AA or AAA batteries, so the power is quite low. However, move up the range to something more robust and professional and could be in all sorts of trouble, although some have a high internal resistance so less of a problem, bit of a minefield.

just linking the pins out is unlikely to work, usually, the ecu is looking for a resistance back rather than a dead short.

sometimes, this fault is caused by moving the seat and causing damage to the wires which spend most of their life in one place and become brittle.

I left mine unplugged in error once, brought up the srs light, replugged it in, after a couple of start cycles, it cleared itself.

obviously any information in this post is at your own risk and no liability is accepted

I haven't cleared the fault codes yet as i'm waiting for the scanner to be delivered from the states, i ordered the autel al619 from amazon, i got a good deal total cost was £105.69 when converted from dollars that includes shipping and import tax, the scanner itself was £80.09.

I was just tinkering hoping i could find the problem while i was waiting, i'll leave well alone with the multimeter, i don't want to cause any further problems.
