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 - 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.

Definition of Terms

The following are definitions of configuration terms:

Programmable Module Installation (PMI)

PMI is a scan tool process which configures settings in a new module. Data used for the PMI process is automatically downloaded from the original module and stored when a scan tool session is started. If this data cannot be retrieved from the module being replaced, the scan tool may prompt for As-Built data entry or display a list of parameter values that need to be manually selected. Some modules are reprogrammed during PMI when a strategy/calibration update is available.

NOTE: It is important that the scan tool identifies the vehicle and obtains configuration data prior to removing any modules. The new module must be able to communicate with the scan tool in order to carry out PMI.

To carry out PMI, refer to Programmable Module Installation (PMI) .

Module Reprogramming

Module reprogramming (also referred to as "flashing") is a scan tool process which updates the strategy/calibration in a module. Module reprogramming is automatically carried out during PMI when a later strategy/calibration is available.

Reprogramming a module with the same level of software will not improve module operation or repair a hardware failure.

NOTE: Module reprogramming should be limited to circumstances where a published TSB procedure recommends doing so.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
