When using the AL519 on compression ignition, I first configured the monitors, deselecting all spark monitors and verifying all compression ign monitors are selected. When I run the I/M test, it displays spark Ign and monitors. I have repeated this test numerous times, and the result is same.
How do I properly configure for Compression Ignition?? Vehicle is 2011 GMC Sierrra with 6.6 Diesel code LML.
