Procedure To Turn Off SDD Error Message
If you wish to deactivate the Service SDD (Speed Dependent Damping) message on the Driver Information Center (DIC) message window, you can do it yourself by using the following procedure.
Four buttons on the AC control are used:
LO (fan speed) = No or skip or increment down
HI (fan speed) = Yes or select or increment up
COOLER = (Blue Button) = decrease by one for each time pressed
WARMER (Red Button) = increase by one for each time pressed
Ignition turned on, car running or not (it does not matter), press and hold the OFF and WARMER buttons on the DIC until the display changes. This is the beginning of the diagnostics mode. After the display changes, release these two buttons. Any stored trouble codes will be listed, and can be copied for future analysis. The automatic function will end at "ECM?".
At that point, press and release the LO button to skip.
At "BCM ?", press HI to select the BCM segment.
At "BCM DATA ?", press LO to skip.
At "BCM INPUTS ?", press LO to skip.
At "BCM OUTPUTS ?", press LO to skip.
At "BCM OVERRIDES?", press HI toi select.
At "BSOO No Overrides", you will need to press the HI button until you reach "BSO8 Option 2". Note down thecurrent value (probably 3) in case you want to restore it later. If you have a 1993 Allante', this value will be 11. Nortmally the new stored value should be "1" on 1989 through 1992 Allantes, and "9" on 1993 Allantes.
Press COOLER button until the number on the right is reduced by 2.
Press and hold ELAP TIME and FUEL USED buttons for at least3 seconds to save the new value in the EEPROM. The display will flash momentarily and then display the newly stored number. Press RESET to exit diagnostics or shut off the ignition.
If you have any questions or the procedure does not seem to be working for you, feel free to call us at 561-844-3938 or e-mail us at Allantesource@gmail.com .
