Principles of Operation
Note. The smart junction box (SJB) is also known as the generic electronic module (GEM).
Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique modules for one vehicle line. These modules must be configured when replaced as part of a repair procedure.
Configurable modules should not be exchanged between vehicles since the settings are unique to each vehicle. Failure to configure a new module may result in improper operation and/or any of the following DTCs setting
- B2477 - sets when a body/chassis module is not configured or is configured incorrectly.
- B2900 - sets when there is a VIN mismatch between the module with the B2900 and the PCM. The stored VIN in either module may be incorrect.
- P0602, P0605 and/or P1639 - sets when the PCM vehicle identification (VID) block is not configured.
- U0300 and/or U0301 - sets when the configuration between 2 or more modules do not match.
- U2050 and/or U2051 - sets when a valid strategy/calibration is not present.
The following are the 3 different methods of configuration
- Programmable module installation (PMI)
- Module reprogramming ("flashing")
- Programmable parameters
Some modules do not support all 3 methods.
Vehicle Identification (VID) Block
Some PCMs contain a memory area called a vehicle identification (VID) block. The PCM VID block commonly stores powertrain configuration items such as VIN, tire size, axle ratio, and whether or not the vehicle is equipped with speed control.
As-Built Data
As-Built data is a VIN-specific module configuration record. During vehicle build, the configuration from all modules is downloaded and stored in the As-Built database. As-Built data will not reflect customer preference items that have been changed from the default state. These items will need to be changed using programmable parameters after the module is configured.
Note. It is not necessary to obtain As-Built data unless directed to do so by the scan tool. This data may be accessed from the technician service publication website.
The following chart lists module As-Built data addresses

| Accessory protocol interface module (APIM) | 7D0 |
| Audio control module (ACM) | 727 |
| Front display interface module (FDIM) | 7A6 |
| Instrument cluster (IC) | 720 |
| Restraints control module (RCM) | 737 |
| Satellite digital audio receiver system (SDARS) module | 782 |
| Smart junction box (SJB) | 726 |
