Program Override
WARNING: This page is about a different car, the 1988 Cadillac Allante and 1987 Cadillac Allante. However, it is still accessible from the selected car via links, so may be relevant.
When trouble shooting a malfunction, the override feature allows testing of certain system functions regardless of normal program instructions. Upon selecting a test, that functions current operation will be represented as a percentage of its full range. This value will be displayed on the CCP. The display will alternate between "--" for 1 second followed by the normal program value for 5 seconds. This alternating display is a reminder that function is not currently being overridden.
- Touching "WARM" or "COOL" buttons on CCP begins override at which time display will no longer alternate to "--". Touching "WARM" button increases value, while "COOL" button decreases value. See Figure. Upon release of button, display may either remain at override value or automatically return to normal program control. This depends on which function is being overridden at the time. If display remains at override value, normal program control can be resumed in one of 3 ways:
- Selection of another override test will cancel the current override.
- Selection of another system will cancel the current override.
- Overriding value beyond either extreme (0 or 99) will display "--" momentarily and then jump to opposite extreme. If button is released while "--" is displayed, normal program control will resume and display will again alternate.
- The override test type is unique in that any other test type within the selection system may be active at the same time. After selecting an override test, touching "OFF" button will allow selection of another test type. However, the CCP will continue to display selected override. By selecting another test type and test, while at the same time touching "WARM" or "COOL" button, it is possible to monitor effect of override on different vehicle parameters.
The available BCM program overrides are as follows:
- BS00
This test will display "none" as no overrides are active at this point. - BS01 - PROGRAM NUMBER
The "PROGRAM NUMBER" override can be controlled from "0" (MAX A/C) to "98" (Max heat). The display will hold the override value upon release of the buttons. - BS02 - LIQUID CRYSTAL DISPLAY (LCD) DIMMING
This override can be controlled from "0" (Max dim) to "99" (Max bright). The display will hold the override value upon release of the buttons. - BS03 - INCANDENSCENT BULB DIMMING
This override can be controlled from "0" (Max dim) to "99" (Max bright), if the park lamps have been turned on. The display will hold the override value upon release of the buttons. - BS04 - COOLING FANS
The cooling fans override will control to "0" (fan off) or "99" (Max fans) as long as the button is held. Normal control will resume upon release of the button. - BS06 - GENERATOR DISABLE
The generator disable override will control to "0" (Gen. on) or "99" (Gen. disabled) as long as the button is held. Normal control will resume upon release of the buttons.
