EGR Test Harness EN-48565

Applications: 2004-Current C/K truck, G-Van, H1 Hummer with 6.6L diesel

The EGR motor and harness connections are difficult to access for diagnosis, and GMPT has many ECMs returned with no trouble found for EGR motor codes. EN-48565 installs between the EGR motor and the harness connection, and has an indicator which lights when the EGR motor function is commanded with the Tech 2. The visual indicator will assist the technician in diagnosing whether the fault is in the ECM or wiring, or actually in the EGR motor. EN-48565 enable the technician to have a more accurate diagnosis, especially due to the limited access to the EGR motor.
