Selecting The Test

Selection of the DATA?, INPUTS?, OUTPUTS? or OVERRIDE? test types will result in the first available test being displayed. If dashes appears in ECC, this indicates that test is not allowed with the engine running. While selecting a specific test, any of the following actions may be taken to control the display:

1. Depressing OFF button on the ECC will stop the test selection process and return the display to the next available test type for the selected system.
2. Depressing LO button on the ECC will display the next smaller test number for the selected test type. If this button is pressed with the lowest test number displayed, the highest test number will then appear.
3. Depressing HI button on the ECC will display the next highest test number for the selected test type. If this button is pressed with the highest test number displayed, the lowest test number will then appear.
4. Depressing RESET/RECALL button on the DIC will halt diagnostics and return system to normal display and operation.
