Hi all,

I hoping someone here maybe able to assist. Apologies if some items below are not completely AWD related.

Last week, whilst driving, I received a 'DSTC Service' and 'Parking Assistance service' warning on the information screen. These both came on at the same time.

I parked up at my destination and on restarting there were no further errors until 2-3days later when they showed again and are now permanent, even after disconnecting the battery.

I've plugged in my vida dice and the network is showing red failed communication from the DEM and PAM. Other links are all green.

The error codes logged are listed below.

CCM-B103087 Left front seat heater - bus signal / message failure - missing message
CCM-103287 Right front seat heater - bus signal / message failure - missing message
BCM - U013600 Lost communication with DEM rear
CEM - U013600 Lost communication with DEM rear
CEM - U015900 Lost communication with PAM
CVM - U041568 Invalid data received from BCM - Algorithm based failue - event information
DIM - U015900 Lost communication with PAM


My plan this weekend is to check the DEM and PAM for 12v and any resistance in the communications link.

Apart from that is seems unlikely that these errors are not all linked to one item. The passenger seat & heater rarely gets used so a problem with this seems unlikely.

If anyone has a recommendation for the best approach on which items to check first I would be grateful.

Regards, Steve
