Hi All

The SRS light has illuminated on my 05 Streetwise.

Nothing unusual happened or was in the car no passengers or anything.

It came on and then after I had stopped and turned the car off and locked it and came back to it an hour later all was ok.

But then on the next journey it came on again and has not gone off since at all.

It comes on as soon as the ignition is on and does not go off.

So any ideas? What are the usual suspects?

Had a Ztt and had a similar problem but the common and known issue was the connector in the wiring of the seat occupancy sensor for the airbag and seatbelt pretensioner. Cleaning it with electrical contact cleaner resolved the problem.

Seatbelt pretensioner connection under seat is the first point to look at. Look under both seats.

It’ll most likely be the above belt pretensioner plugs, or possibly the slip ring behind the steering wheel.

Ideally the fault codes need reading to diagnose rather than guessing.

Yep i'll see if i can borrow a code reader prob best place to start.

My 45 SRS light came on and it was this. Dodgy connection under seat

It will need to have the capability to read SRS codes, the basic/midrange ones can't.

If you are close to Letchworth I don't mind hooking it up to my PScan, alternatively if you are going to the MK Museum event I believe the Coupe Owners club have the equipment to read the DTC's, too.

Different car but my old BMW had this issue - the seat sensor pad had failed on the passenger side. I fitted a little plug on the loom which makes it think the seat is occupied. In a crash both airbags would go off rather than just the drivers but I figured such a crash would write the car off anyway so the extra repair cost was irrelevant. Not sure if that’s a possibility

Hi Yes it appears i've just found that out.

SRS light still on but no SRS codes.

But slightly troubling is that i have 2 other codes, P0302 cylinder 2 misfires and P0340 Camshaft sensor A Bank 1 circuit malfunction.

Cleared those codes but after starting the engine and rescanning they are back, but the car appears to drive fine, doesn't sound like it misfires but hey who knows.

Looks like i'll be trying the seat connectors as per my old Ztt but any ideas on the misfire fault code?

Cheers Bean

First thing I would do with a misfire code is to swap the ignition coils around and see if the misfire moves cylinders.
