    Hello, Administrator.
    VIDA can only monitor VGM PIN
    The other PINs can only be obtained by using the VIDA ordering software. I'm sure you know this.

    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

    Can anyone shed some light on this strange fault?

    I've got a recurring "impulse sensor fault" that come back pretty much immediately.

    Up to now ive changed the crank ,Cam sensors. Changed the crank sensor connector ( as the wires had split insulation)

    I've checked all the ecu connectors, cleaned them and checked for corrosion (non apparent)

    Ive then checked the 3 wires from the ecu connector to the crank for continuity/high resistence, and everything checked out there.

    The only then i can think thats left us the ecu itself.

    The car runs and drive with no warning lights (just the impulse sensor faulty message when ypu scan for codes.  The cars definitely down on power.  It cant get past 60mph or rev pas 2500rpm.  I suspect its stopping the vnt in the turbo from moving.

    l've logged the rpm signal coming from the crank sensor and theres nothing wrong with it. Signal is constant with no dips or breaks in signal.

    5v and sensor ground look to be good

    The only thing that does look funny is theres 10v on the signal line. Im not sure if this is normal or not as I can't see the raw data for the crank signal line with my scanner.

    Any help would be appreciated
