Fiatecuscan Lambda fault code

Guys help needed here. I just completed my first OBD tests using fiatecuscan and have a few error codes.

Error code 08 - Driver squib circuit. The Airbag activating circuit indicated by the code is shorted to Ground.

Error code P1749 - Steering Wheel Controls. Gear selection button error on steering wheel. The reason for this fault is that ECU has received very high signal from the sensor.

Error Code P1762. CAN line message transmission/reception error
The reason for this fault is that ECU did not receive signal from the sensor.

The above all likely relate to the steering wheel change a couple of weeks ago and the disconnected audio controls on the wheel so not a major issue for me - although is the airbag dangerous like this? Anyway will get that looked at.

But the other error relates to a Lambda sensor but can't find any info on it:

Error Code P0156 - Lambda 2 signal below catal

Any help as to what this means or how to fix I'd be grateful. I don't have any running issues with the car currently other than a slighty fluctuating exhaust note every so often at idle when at full operating temp. Every 15-20 secs the sound dips for a couple of seconds then returns. The revs very slightly dip at the same time but hardly visible on the rev counter. Ragazzon exhaust fitted.
