My fbh has thrown a fault which is U3000-16 (2F) Control module - General electrical failure - circuit voltage below threshold.
Any ideas anyone?Volvo XC60 - does all that the D4 should have done

I had a similar code on my MY13. Gave the battery a good charge on the CTEK and then cleared the fault with my IID Tool. It's not come back since, and the FBH has been working fine. D4 MY14 XXV - RLD/IID BT
D4 MY13 HSE Lux - RLD/IID BT
P38 RR - Sad parting
110 - Even sadder parting
S3 88" - Still going strong after 23 years of ownership

The fault codes are pretty good at describing what's up. Sometimes. 06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti
Any issues with the site let me know!
Battery voltage is normal. Is this a fbh pcb fault?Volvo XC60 - does all that the D4 should have done

It is coming back after clearing it?06 D3 SE / 15 LR D90 XS SW / 88 LR 90 Td5 / 68 BMW 2000 ti

Yes. I have seen it once before and cleared it and now its back again. The car goes in on Tuesday for the 3 degree fix and I'll let the dealer take a look.
I am interested to know if others have had this fault and how it was fixed.Volvo XC60 - does all that the D4 should have done

Out of interest, what is the resting voltage of your battery? Another question would be which battery are you measuring the voltage of? Being a MY16, you'll have the stop/start system and therefore a second battery.
I have no idea what runs off the auxiliary battery versus the cranking battery, but it could be somewhere to look? When I bought mine, the battery had been fubared by the time I got it, so 'persuaded' the dealer to fit a new one, which I then condition charged. Touch wood, I've had no problems since. 8)D4 MY14 XXV - RLD/IID BT
