2016 XC90 SRS-B11721A (and other DTCs) - VDASH won't clear

[ejfhorne]

Hi all

This is my first post and first fault with my 2016 XC90 D5.

I've had some battery issues during lockdown and I think it's probably on the way out.

Recently and SRS Service Urgent warning has been on the display. It was intermittent but now permanent.

I had a 2009 XC90 D5 previously and was quite familiar with VIDA so I hooked up my DiCE to VDASH and cleared all the codes (seemed to work very well). These were the ones left:

DTCs:
ECM-P008A7B - Low Pressure Fuel System Pressure - Too Low. Mechanical Failures. Low fluid level
TCM-P011586 -
VCM-U105101 - WLAN Module- - General electrical failure
VCM-U105117 - WLAN Module- General Electrical Failures- Circuit voltage above threshold
VCM-U122B11 - BM circuit short to ground- General Electrical Failures- Circuit short to ground
VCM-U122C11 - BP circuit short to ground- General Electrical Failures- Circuit short to ground
SRS-B11721A - Starter Motor Cut Off - Deployment Control- General Electrical Failures- Circuit resistance below threshold

I know about the VCM and it's on my list to fix. I'm a bit confused by the ECM fault but I do need to get the SRS one fixed. Does anyone have any ideas or would someone with a VIDA subscription be able to take a quick look at the fault finding? I would be very grateful.

I look forward to learning more about DIY'ing the SPA XC90!

Many thanks
