Hi All,
My V70OR has manual seats. I'm trying to upgrade the drivers seat to a electric adjustable model. The car was not pre-wired for this and had no CAN-bus connection for it. The seat came from a 2000 V70 P2. Therefore I made a extra connection on the LS CAN-bus on the node directly behind the CEM. This is the location given by the Volvo electric diagrams.
I succeeded adding the PSM to the CAN-bus and the software recognizes the module, only leaving it yellow.
The dtc the CEM is generating is 1A54 "signal missing from PSM". The software however does return the correct hardware number of the unit, so it must be able to communicate with it.
I tried the option to revert to original, but this generates a message that this cannot be done and that I should contact the developer. In one occasion the PSM appeared green in the CAN-bus overview, making it look OK. Unfortunately, the controls of the seat did nothing.
I did test another PSM, but this model wasn't recognized by the CEM at all. Altough it seems to work OK, since I was able to adjust the seat the first 40 seconds or so after power up.
Is there somebody who can help me with this problem? I hope so and thanks in advance!
Kind regards, Martin
