Allante V8-273 4.5L (1991)
Body Control Module: Reading and Clearing Diagnostic Trouble Codes
Override
BS00
This test will display "NONE" as no overrides are active at this point.
BS01
The program number override can be controlled from "O" (Max A/C) to "98" (Max heat). The display will hold the override value upon
release of the buttons.
BS02
The LCD dimming display can be controlled from "O" (Max dim) to "99" (Max bright). The display will hold the override value upon release
of the buttons.
BS03
The incandescent bulb-dimming override can be controlled from "O" (Max dim) to "99" (Max bright) if the park lamps have been illuminated.
The display will hold the override value upon release of the buttons.
BS05
This shows the current state of circuit 856, the TCS enable output. The system operates normally with the output alternating between "HI" and
"LO". Pressing the warmer button disables the TCS system by forcing the output to the "HI" state.
BS06
The generator disable override will control to "0" (generator enabled) or "99" (generator disabled). The display will hold the override value
upon release of the buttons.
BS07
This allows the ability to change the vehicle option content information stored in the BCM EEPROM. The BCM uses this option information
to determine how to operate the displays and other electronic devices Incorrect option content information in the EEPROM may cause many
different problems. Upon selection of this override the option content information will be displayed as a number on the DIC. To determine the
proper option 1 number, calculate the sum of the applicable numbers from the following table:
If vehicle is equipped with:
Add
Non-French Canadian displays
128
Domestic displays (US cars only)
64
Japanese displays
1
Oil level sensor
32
Output switch module #13 (all cars)
16
Two filaments in each tail lamp (all cars)
2
Canadian daytime running lights
8
Sweden/Norway daytime running lights
4
If necessary, the "WARMER" and "COOLER" buttons can be used to increase and decrease the Option 1 number. When the correct number is
reached, simultaneously press and hold the "ELAPSED TIME" and "FUEL USED" buttons for three seconds to permanently store the correct
value in the EEPROM. The display will blank momentarily and then display the newly stored number.
BS08
This allows the ability to change the vehicle option content information stored in the BCM EEPROM. The BCM uses this option information
to determine how to operate the displays and other electronic devices. Incorrect option content information in the EEPROM may cause many
different problems. Upon selection of this override the option content information will be displayed as a number on the DIC. To determine the
proper option 2 number, calculate the sum of the applicable numbers from the following table:
If vehicle is equipped with:
Add
Low coolant sensor
1
Speed dependent damping
2
Great Britian daytime running lights (no cars)
4
If necessary, the "WARMER" and "COOLER" buttons can be used to increase and decrease the Option 2 number. When the correct number is
reached, simultaneously press and hold the "ELAPSED TIME" and "FUEL USED" buttons for three seconds to permanently store the correct
value in the EEPROM. The display will blank momentarily and then display the newly stored number.
