Only for add more info. The K60 (Steering Column Lock Control Module) module, stores too Pin and Vin, but is not part of the immobilizer. Then, if you buy a used K60 module, you need change pin and vin too in this module.

Wow, thanks for the information.

Still learning.

does the front camera module store the VIN/PIN, too? Or the calibration is possible without knowing the VIN/PIN from the donor? I don´t see it in the list, but just asking to be sure. Thank you

sorry, I meant the front radar, not the front camera

If I already drove the car with the new IPC can it be unlocked? I didn't know this would be an issue until this point

Yes but you will need to dump the IPC eprom chip and remove the lock code.

Related info for dashes (------) in speedometer:

The instrument cluster displays the engine coolant temperature, fuel level, vehicle speed and the engine speed based on the information from the engine control module (ECM). The ECM sends information via serial data to the body control module (BCM). The BCM then sends the information via serial data to the instrument cluster to display the engine coolant temperature, fuel level, the engine speed, the vehicle speed and the distance travelled, either in kilometers or miles, based on the vehicle requirements. The instrument cluster will display dashes when its VIN does not match the VIN received from the BCM.

 

If the VIN mismatch is corrected the odometer will once again be displayed in the instrument cluster. If the vehicle is driven for a calibrated distance with a VIN mismatch, it will cause the instrument cluster odometer to enter into an error mode and lock itself. When this occurs the dashes will remain on the display even after correcting the VIN mismatch. The vehicle odometer status data display on the scan tool can be used to identify a locked odometer. The only way to unlock the instrument cluster (clear the dashes from the display) is to perform an SPS programming event. Failure to follow the diagnostic and programming procedures may result in either an improper odometer value or a module replacement.

Resume: Perform a BCM config (type 4, not a calibration reprogram) will unlock the speedometer dashes always pin/vin was correct.
