Override Displays

When trouble shooting a malfunction, the BCM override feature allows testing of certain system functions regardless of normal program instructions. On Reatta and Riviera models, upon selecting a test, that selection's current operation will be represented as a percentage of its full range. This value will be displayed on the CRT below the "EXIT" key pad.

Pressing key pads above or below "OVERRIDE" ("WARM" or "COOL" on Toronado) on the CRT begins the override. When in override, pressing key pad above "OVERRIDE" increases the value, while pressing key pad below decreases the value. Normal program control can be achieved in 3 ways.

• Selection of another override test will cancel the current override.
• Selection of another system will cancel the current override.
• Overriding the value beyond either extreme (0 or 99) will display "---" momentarily and then jump to the normal program control.

The override feature, or test type, is unique in that any other test type within the selected system may be active at the same time. After selection of an override test, pressing the "LEVEL" ("OFF" on Toronado) key pad will allow selection of another test type, yet the CRT will continue to display the selected override. When selecting another test or type, and then pressing the key pads above or below "OVERRIDE" ("WARM" or "COOL" on Toronado), it is possible to monitor the effect of override on different vehicle parameters.
