Hi All,

Any advice gratefully received here.

I was advised to fit a new clock spring on my qashqai j10 (07) as the horn stopped working.

When I removed the old clock spring I found the wiring looked very strange! [photo link below]
The yellow connector which links the wiring from the main loom into the clock spring carries 3 wires (Y, Y/R, Y/L).

However these 3 wires had all been clipped (I have since stripped them back a little as the photo now shows, but the wire ended flush before).

Can anyone advise why there are 2 resistors soldered on to the end of the yellow wire??

One resisitor I presume was fed to the yellow wire end in the connector, and the other resistor was soldered to connect the yellow wire to the yellow and blue wire? Is this normal?? I would expect no resisitors here and the wiring just to terminate straight in to the connector? The repair manual shows no additional resistors that I can see!

The airbag system showed no fault before despite this weird wiring set up - can anyone advise how this should look and what was the previous owner doing with this soldering? Am wondering if the airbag was even connected before?
many thanks

Added pic showing

- the three wires still in connector

- the three wires from harness with 2 resistors attached to Yellow, and 1 of those also soldered to Yellow/Blue...

Welcome to this forum

Looks very peculiar

Calnorth might be able to elucidate

Anything like that around the spiral cable unit automatically alerts me to Air Bag interference. Is your SRS lamp always off?

General Info:
The airbag connectors are bright yellow in order to more easily identify the airbag cables and connectors.

Inside the connector there is a jumper which prevents the airbag from being deployed unintentionally if work is being carried out on the airbag system. This could occur as a result of static charging, for example.

The jumper is a contact which connects the two contacts inside the connector when the plug connection is disconnected, in order to eliminate any potential.

Hi - and thanks both for your assistance.

No I think the airbag light was on before at ignition and showing no errors.

After disconnecting the battery, I tried connecting the wires from the clockspring to the loose wires in the harness and it started giving a flash pattern error of 3secs + 2x 0.5secs - ie air bag module error, for which repair manual says check harness wiring first.

Am I right in thinking those soldered on resistors are definitely not found as standard in a qashqai j10?

The bit that puzzles me (aside from the resistors) is that the wires out the back of the clockspring were cut clean (and short), and had no sign of solder on them so it is not obvious which of those were previously connected to the three wires in the harness.

Is it also normally the case that each of those three wires (Y, Y/R, Y/L) would just go straight from the harness into the clockspring?

Thanks very much.

The connection should be without those amateur soldered resistor additions. They appear to be 2.2 ohms each. Look on eBay for the QQ clock spring unit as they show clean one piece cable & plug connection.

At a guess it looks like someone has added the resistors to present a specific load to the Air Bag Control Unit. Stop it signalling an error somewhere?

Very dangerous stuff.

Thanks, calnorth - yes seems extremely dodgy!

I have only now checked the MOT history online and - yes indeed - it was failed 3 years out of 5 on an SRS Fault! (prior to me buying it 2 years ago).
Each time it was subsequently passed by the same garage in 2013/14/17, presumably after they somehow, er, fixed it.

I bought the car from a dealer in Dec 2018 via an autotrader ad.
Would the dealer/seller have any responsibility in a case like this where dodgy/dangerous SRS wiring is discovered in the car 2 years after purchase?

Not sure what can be done about it....you probably need to contact the MOT authority DVSA.

Hmm.... I've just Googled:

< airbag fault cured with resistors >

Lots of references for a variety of cars. It seems you can even buy them on eBay!:
