Circuit/System Testing
Important: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or
replacement of the affected.
* SDM
* SDM wiring harness
1. Ignition ON, verify the scan tool Primary Key Status displays Valid.
瀚慖f not the specified value, verify the scan tool SDM Primary Key matches the Received Primary Key. If the key does not match, perform
the Setup SDM Primary Key in BCM procedure.
2. Ignition ON, verify the scan tool Secondary Key Status displays Valid.
瀚慖f not the specified value, verify the scan tool received VIN Digits 2-7 match the vehicle VIN.
* If the VIN does not match, reprogram the BCM and perform the Setup SDM Primary Key in BCM procedure.
* If the VIN matches, reprogram the SDM, ensure the correct SDM calibration is used and perform the Setup SDM Primary Key in BCM
procedure.

DTC Descriptor
DTC B1008 42
- Calibration Data Not Programmed Calibration Data Set Not Programmed
Circuit/System Description
When the ignition is turned ON, the rear object sensor control module performs a self-test to verify if a critical malfunction exists within the
system. During the power-up mode, the rear object sensor control module checks for a valid calibration data set.
Conditions for Running the DTC
* DTC B1325 is not set
* Ignition voltage is between 9-16 volts
Conditions for Setting the DTC
A valid calibration is not detected upon module power-up.
