    Hi,

    Ive got a SRS warning which has been diagnosed as a Satellite B Pillar Left (SBSL) Module failure. Apparently the module is no longer communicating?

    I've been told the module is located in the door itself but some of the info I have been able to find suggest it is located somewhere under the seatbelt reel on the b pillar?

    Can anyone tell me where this module can be found and how would be best to remove/replace?

    Also, here appear to be several part numbers on realoem for this module which are shown as "ended" but only one with a cost next to it? Does this mean that any of these part numbers can be used but the one with the cost next to it is the most recent revision? Or am I getting this wrong?

    Thanks in advance!

    Hi,

    Thought I would give a quick update of events since my first post to see if anybody out there can shine some light on the fault codes I have identified.

    I took the car to a local indie who cleaned the connections and re-coded the module. This appeared to fix the restraint system warning for a couple of months before it returned once more. As a result I decided to obtain a cable and software (INPA, DIS, etc) so that I could read and clear the codes as necessary, which has now become weekly occurance - the car will be fine for a week or so then "bong" the Restraint Warning is back again! I keep resetting and it keeps coming back but doesn't seem to be getting any worse (probably reset about 6 times now)?

    On reading the codes using INPA and DIS, I get the following:-

    982D CAN SBSL No Message
    98AD CAN SBSR No Message
    96B1 CAN TMBF No Message
    FFFF CAN Communication Fault
    96FD TMBF Voltage Supply Limit Value Undershot
    93DA Deactivation Front Passenger Door Module
    93AE - Not sure about this one?

    I believe this could be either a low voltage issue or a door module fault? However, the battery appears to be good (typically 14-14.5 Volts when driving), so could this be voltage regulator related?

    Can anybody advise on anything I can do to distinguish between voltage issue or module issue or anything else which could be a cause?

    Thanks,

    Farmerc

    the fault could be a connection or power supply fault , or even a control unit fault , just because it says its faulty does not mean to say that part is faulty .

    Thanks for that - certainly a few more things to consider here and more questions?

    In the case that the door module failed either as a result of a voltage issue or due to a module fault, why would comms with both SBSL and SBSR? My knowledge of the system is limited so this could be completely wrong?

    Okay - The fault has been traced to a faulty passenger door module which was intermittently loosing comms. As a result this would deactivate the left and right satellite modules throwing up a restraint system warning.

    I've now replaced the module with a used module making sure the part numbers were exactly the same. However, whilst I've managed to clear the faults and the module seems to be working fine, I'm now getting a VIN mismatch fault. I guess this is because the VIN on the module doesn't match the VIN of my car.

    Does anybody know how to change the VIN on this module, or is there any instructions available on how to do this. I've got WinKFP, DIS, INPA, NCS-Expert, etc but I'm not sure which to use and even if I did I wouldn't know how? I've used INPA and DIS to read and erase fault codes but that's as far as it goes!

    Can anybody help or advise?

    Thanks in advance,

    Farmerc
