    Default CIM problems Vectra C

    Hi, it all started when the cruise control turned off when I pressed the deceleration button. I bought an op-com and thought that the cim module needs resetting. so I did that, then the car would not start, found I needed to program the keys. Now the cruise control turns off whenever it wants an I get

    Source Address: CIM
    B3794 - Switch Cruise Control Circuit Malfunction
    (08) - Not present
    U2103 - No Communication with CAN-Bus (High Speed)
    (00) - Not present

    Source Address: AIRBAG SDM
    U2139 - Invalid Data from CIM (Steering Column Module)
    (00) - Not present

    Source Address: PAS
    U2139 - CAN-Bus No Communication with CIM (Steering Column Module)
    (00) - Not present


    and this one started to show about the time I reset the cim module, don't know if it's related:

    Source Address: IPC
    U2105 - CAN-Bus No Communication with ECM (Engine Control Module)
    (7F) - Not present


    Can someone tell me if I need to reset/program other ecus after a cim reset with opcom, and if so how should I do this?

    Thanks

    Your car is <2005? Vectra C?
    ABS Light and ESP (if you have) have illuminate without reason?
    I think your problem is CIM, a very common problem on Vectra C/SIGNUM <2005.
    Your only hope is replace CIM. No repair kit avaible.
    I hope i'm wrong, but....

    PS: In attach you will find 2 pdf regarding your problem. I hope will help.

    yes, it's august 2004... thanks for the info.

    There are some things I don't understand about the op-com. When it sais reset module, what does this reset do? does it erase the memory of the module and then you need to reprogram? because when I reset the cim it did erase the keys but I don't remember me reprogramming the cim module. the abs light and airbag does not light up. the only problem is with the cruise control.

    hi m8
    just had my cim replaced on my vectra c after doing the normal checks.
    check and clean the abs plug
    check the abs sensor
    and check all plugs from the cim to the control modules.
    but if all that is wrong is the cruise control. check the clutch return spring .
    best way to do this is that when the cruise control cut out hold the clutch pedal up and see if the cruise control work then.
    if it that then you will need to get the spring repair kit from vx only about a tenner

    The CIM is the Gateway for this vehicle, if you will reset the CIM it means
    1- this module is ready for replace
    2- this module is ready for reprogramming
    try to reprogram the module, and see if the communication codes of the Can-bus will vanish or not if these codes vanish and everything is ok check curise control programming on CIM, IPC, ECM
    if not then measure the signal ,and replace the defective ECU

    Problem is not SOFTWARE but Hardware ok?
    they tried to explain before.

    if you replace with new you have to code and learn keys + pin.

    if you replace with secondhand just copy 93C66

    Before the new CIM is fitted, first note the following:

    Security Code
    V.I.N.
    Mechanical key number
    Variant encoding
    High Speed CAN configuration
    Mid Speed CAN configuration
    Low Speed CAN Configuration
    Run a full DTC scan and save the results
    Make sure that the V.I.N. in the other control devices consistent with the car
    Reset the old CIM

    Install the new CIM

    Configure the CAN-High, Low and Middle configurations
    Program V.I.N. and mechanical key number in the new CIM
    Program Immobiliser function, (choose CIM installed)
    Program the available transponder keys to the new CIM
    Reset the following devices:
    IPC
    REC
    BCM
    PDM
    DDM
    Switch the ignition off and wait at least 15 seconds
    Program the security code in the following steering devices:
    IPC
    REC
    BCM
    PDM
    DDM
    Configure the variant coding of the new CIM
    The final step is to calibrate the steering angle sensor

    First of all, if you reset any controller using op-com or tech 2, then all that happens is that the security code is erased,the original settings and configurations remain the same.Second hand cims can be reset and reconfigured, the only controller that cant be reconfigured is airbag.cim takes a fair bit of configuring,i use tech 2 and and only work on VX , but still have bother at times.
