Toronado (ECC Panel)
Selection of the "DATA", "INPUTS", "OUTPUTS" or "OVERRIDE" test types will result in the first available test being displayed. If "= =" message appears, this test is not allowed with engine running. Turn engine off and repeat sequence.
The last 4 characters of display will contain a test code to identify selection. The first 2 of these characters are letters which identify the system and test type (i.e. ED for ECM DATA) and last 2 characters numerically identify the test (i.e. ED01 for Throttle Position). When selecting a specific test, the following actions may be taken to control display:
- Pressing the "OFF" button will stop test selection process and return display to next available test type for selected system.
- Pressing the "LOW" fan button will display the next smaller test number for selected test type. If this button is touched with lowest test number displayed, highest test number will then appear.
- Pressing the "HI" fan button will display the next larger test number for selected test type. If this pad is touched with highest test number displayed, lowest test number will then appear.
Upon selecting an "OVERRIDE" test function, current operation will be represented as a percentage of its full range. This value will be displayed on ECC panel. The display will alternate between "--" and normal program value. This alternating display is a reminder that function is not currently being overridden.
Pressing the "WARM" or "COOL" buttons on ECC panel begins the override, at which time the display will no longer alternate to "--". Pressing the "WARM" button increases value, while pressing the "COOL" button decreases value. Normal program control can be resumed in one of 3 ways.
- Selection of another override test will cancel current override.
- Selection of another system (ECM, BCM or IPC) will cancel current override.
- Overriding the value beyond either extreme (0 or 99) will display "--" momentarily and then jump to opposite extreme. If button is released while "--" is being displayed, normal program control will resume and display will begin alternating.
The override test type is unique in that any other test type within the selected system may be active at the same time. After selecting an override test, pressing the "OFF" button will allow selection of another test type (DATA, INPUTS or OUTPUTS). The secondary display panel will continue to display the selected override. By selecting another test type and test, while at the same time pressing the "WARM" or "COOL" button, it is possible to monitor the effect of override on different vehicle parameters.
