Side lights

[CRH]

I don’t know whether it’s relevant but at the moment I have a failed steering column module, meaning I have no indicators or high beam, along with lots of warnings such as reduced braking. . However my hazard warning lights still work.

That's one thing going for it

The hazard switch appears to be wired directly to the BCM so the SCU plays no part. The other lights are controlled from the SCU over CANbus to the BCM.
