2005 XC70 SRS reset. No communication to many modules

[tonygee]

Hoping someone can help.

I've a 2005 model year XC70. I have a Vida Dice clone. I did the classic disconnecting the AC panel without disconnecting the battery and triggered the SRS light and SRS service urgent message.

Thought I could easily reset it with the Dice, but I cannot communicate with the SRS module, or many other modules, see photos. No fault codes are stored, presumably because Dice cannot access the modules.

I've checked the CEM connections externally for any signs of water ingress, but they're perfectly clean and there is no evidence of water ingress.

I have the DIM out at the moment, and it's the later model with surface mount LEDs etc, which I thought was relatively trouble free.

Any advice on where I should be looking? Thanks in advance.
