2005 XC70 SRS reset. No communication to many modules
 

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.

Looks like you have a dead Dice.
Has it ever successfully connected?

Thanks for the quick reply. It has connected to some modules and cleared codes, but never to those modules in red.

The Dice is knackered unfortunately.
Communication to all available modules is one of the many things I test on Dice and VCX before selling them and if they have a sea of red blocks like in your pictures, they get sent back.

If you check various Parameters from the affected modules in the Vehicle Communication section, you'll find inconsistent or no data from them.

You can check the Dice and confirm its operation on an alternative known working Volvo model but I think you're going to have exactly the same outcome.

Thanks again Simon. Could you PM me the current price and your payment details for a replacement Dice please.

Pm sent.
Just a quick question though.
Have you had Dice and Vida connected with the above problems when the DIM and everything else is plugged in or have you only read the car with the DIM removed?

Yes, these scans were carried out with everything intact. Have only just removed the DIM to inspect it.

Ok. It was just a thought as the DIM is not just a speedo and is interconnected to a surprisingly number of other modules.

All of the red network errors on a fully connected system still point to a faulty Dice then.
