Engine Control Module (ECM) Diagnostic Trouble Codes (DTCs) Group 28 Troubleshooting Engine Control Module (ECM) Diagnostic Trouble Codes (DTCs) The manufacturer scan tool is the preferred tool for performing diagnostic work. Contact your local dealer for more information or visit “www.premiumtechtool.com”. Note: The use of a scan tool is necessary to perform diagnostic work as well as clearing of any diagnostic trouble codes (DTCs).
Engine Control Module (ECM) Diagnostic Trouble Codes (DTCs) Group 28 System Electronic Control Unit (ECU) Overview The engine control module (ECM) monitors and models (using physical principles) engine parameters to monitor the engine system’s performance in real time. This is performed to aid the ECM with its self diagnostic capabilities. Many sensors are used for input to the emission control system.
