Selection of a test type will result in the first available test being displayed. If a "Select ERR" message appears, this test is not allowed with the engine running. Shut engine off and begin again.
Four characters of the display will contain a test code to identify the selection. The first 2 are letters which identify the system and test type. For example, the letters ED stand for ECM DATA. The last 2 characters numerically identify the test. For example, ED01 stands for ECM DATA for throttle position. When selecting these tests, 3 alternatives are available:
- Pressing the "EXIT" key pad will stop the test selection process and return the display to the next test type for the selected system.
- Pressing the "NO" key pad will display the next smaller test number. If the lowest number is already displayed, the highest number will then be displayed.
- Pressing the "YES" key pad will display the next larger test number for the selected test type. If this key pad is touched and is already at the highest number, the lowest number will then appear.
