ECM Data

ECM Data







You can retrieve data from the ECM by connecting a scan tool or the HDS to the data link connector (DLC). The items listed in the table below conform to SAE recommended practice. The HDS also reads data beyond that recommended by SAE to help you find the causes of intermittent problems.

NOTE: The "operating values" listed are approximate and may vary depending on the environment and the individual vehicle. Unless noted otherwise, "at idle speed" means idling with the engine completely warmed up, in neutral position, and the A/C and all accessories turned off.
