Actuator Output Circuit Test

The third item on the menu the EVO control module will output to the Star Tester is DTC 25. This represents asking the service technician whether he/she would like to "Perform actuator test?". If the service technician releases the HOLD/TEST button for one second, then latches the HOLD/TEST button down again within eight seconds after receiving DTC 25, the EVO control module will enter this self-test and automatically test for the actuator faults. If faults exist, the control module will store the appropriate codes in memory, output these codes to the Star Tester and complete this test by outputting DTC 22 to the Star Tester which signals end of test. If no faults exist, the control module will complete this test by outputting DTC 26 to the Star Tester which represents "Test passed."
