Corsa D BCM locked up? after a flat battery

[the_big_d]

OK Corda D's after the battery has gone flat the vehicle appears to have an immo fault but i believe some of the modules have become misaligned?
I believe Opcom can sort this but what exactly is it that needs to be done?

[pawl]

Have you tried resetting the module and re-teaching? pin is known ?

[the_big_d]

Im going to have a look at the car tomorrow, not been near it yet. Will i be able to pull pin with normal key programming tools or are they unlikely to pull the pin whilst it is in this state?
Assuming i can get pin Which modules need re teaching, what am i actually doing? is it just re entering the pin?

PIN from OBD....... IPC, DIS, ECM

[pawl]

read the dash the volume should be a pin ,or carpass maybe it is ,as I remember correctly it is done to reset the module and program the pin

PIN from OBD....... IPC, DIS, ECM
Yes but will normal OBD tools pull the pin whilst it is in this state? I have several tools that will pull the pin on these but not sure if they will work if the car is in this state?

[davorOS]

yes You can rwd it in this state
I do it from ECU

recode SDM and BCM and car start most time
only on few I had to code keys and ecu

ive never used opcom for this but am told it works well , i tend to use abrites . yes you can still read pin , do this first , then i normally do fault scan , every unit with faults i re enter pin in each unit and clear faults , do same with bcm and ecu then reset and rematch the bcm and ecu , run fault scan again , when no faults i recode keys and job done , not failed on one yet doing this with avdi .

this is silly season where i normally get 1 or 2 of these corsa D a week as temperatures drop and bad batteries die on badly maintained cars .

All sorted with opcom. Reset ECU, IPC, airbag & BCM.
didnt try to read the pin as the car pass was in the car.
