#About<\/strong>
\nThis is an automated test that manually operates the EFC Actuator to ensure that the EFC Actuator is functioning properly. The test runs for a maximum of 60 seconds.<\/p>\n

To perform the test:<\/strong>
\n1). Attach the PC\/ Laptop to a running engine in a non-moving vehicle, or Engine stopped with key switch ON. Read More: How to Connecting CUMMINS Engines using Cummins INSITE Software.<\/p>\n

2). Select EFC Actuator Override Test from the list in the ECM Diagnostic Tests Wizard (refer to Figure 1.1 above). Click Next, and the EFC Actuator Override window opens.<\/p>\n

\"\"<\/p>\n
