Go To Pinpoint Test A, to diagnose "The PCM Does Not Respond To The Scan Tool". See: Pinpoint Tests/Pinpoint Test A: The PCM
Does Not Respond To The Scan Tool
5. Carry out the network test.
-
If the network test passes, retrieve and record the continuous memory DTCs and proceed to Step 6.
-
If the network test fails, GO to Symptom Chart to diagnose the failed communication network. See: Symptom Related Diagnostic Procedures
-
If a module fails to communicate during the network test, GO to Symptom Chart. See: Symptom Related Diagnostic Procedures
6. Retrieve and review the DTCs.
-
If the DTCs retrieved are related to the concern, go to DTC Charts. Follow the non-network DTC diagnostics (B-codes, C-codes, P-codes)
prior to the network DTC diagnostics (U-codes). For all other DTCs, refer to the Diagnostic Trouble Code (DTC) Chart in Body Control
Systems. See: Diagnostic Trouble Code Descriptions/Communications Network See: Body and Frame/Body Control Systems/Testing and
Inspection/Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) Chart
-
If no DTCs related to the concern are retrieved, GO to Symptom Chart. See: Symptom Related Diagnostic Procedures

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 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.
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. To carry out PMI, refer to Programmable Module Installation (PMI) See: Programming and Relearning.
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
