SPECIAL TOOLS Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool
Scheme 89
Principles of Operation
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 incorrect operation and/or DTCs setting.
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 Vehicle Identification Number (VIN), tire size, axle ratio, and whether or not the vehicle is equipped with speed control.
Transmission Identification
PCM controlled transmissions have a solenoid strategy identification tag located on the left side of the transmission case with a 13-digit solenoid strategy number. The solenoid strategy is correct if the 13-digit number displayed on the scan tool matches the number listed on the tag. If the numbers do not match, then the solenoid strategy identification etched on the main control will need to be compared to the identification displayed on the scan tool. The solenoid body strategy must be downloaded to the PCM if the identification on the main control does not match the identification displayed on the scan tool, or transmission damage may result.
