    Lightbulb Bypassing Service Ride Control?

    Does anyone know how to bypass the electronic strut system so the service ride control message does not appear on the dash?

    I need new front struts, I was hoping to just get regular struts w/o the sss/electronic hook up b/c they are cheaper. Will that work?

    Yes, put regular struts. Here is how to disable CCR message. It worked on my car. The message was indeed annoying.

    1991 Eldorado and Seville with Computer Command Ride (CCR): Refer to the Service Manual page 8D-12. Set the BCM override value BS09 to 0 by using the warmer and cooler buttons. Store this value by pressing the Econ button on the climate control panel and the Instant Econ button on the Fuel Data/Drivers Information Center for about five seconds. The new value will be stored even through the indicator does not flash. Remove the key from the ignition. Disconnect both battery cables from the battery. When both cables have been disconnected, touch the ends of the cables together and hold for five seconds. This will discharge the capacitors in the system and allow the system to perform properly when the battery cables are reconnected. Advise the customer they will have to reset all radio stations and clock.

    Document #740707
    Info -- Procedure to Disable Illumination of Service Indicator AFTER installing Passive Struts #00-03-11-001A
    Applies to:
    • 1989-1992 Cadillac Allante
    • 1991-1993 Cadillac Eldorado, Seville
    • 1991-1995 Cadillac DeVille
    This bulletin is being revised to clarify when this bulletin may be used to turn the service suspension lamp off. Also, a step has been added to the 1991 Cadillac Eldorado and Seville repair. Please discard Corporate Bulletin Number 00-03-11-001 (Section 3 -- Suspension)
    Some owners may bring their vehicles in for service with an illuminated service suspension light. The service suspension indicator lamp is telling the owner that the vehicle is due for strut/shock replacement, a maintenance item. The customer may elect to have passive struts installed in their vehicles due to the repair cost savings and/or parts availability. The installation of passive shock/struts will result in handling characteristics which are the equal to a like vehicle without the computer controlled ride, with all other components such as tires, tire pressure, springs, etc. being equal. The installation of (4) new passive struts will cause the continued illumination of the service suspension indicator. If desired by the customer, the service indicator may be disabled AFTER THE INSTALLATION OF THE (4) NEW PASSIVE STRUTS, using the appropriate service procedure listed below. This bulletin DOES NOT authorize this procedure unless (4) NEW PASSIVE STRUTS WERE INSTALLED ON THE VEHICLE.
    The wiring harness going to each strut and or chock assembly should be cut and taped back to clean-up the appearance both under the hood and under the vehicle. In addition, each specific vehicle will require a modification as outlined below:
    • 1989-1992 Allante with Speed Dependent Damping (SDD): Refer to the Service Manual page 8D-13 (1989) or 8D-14 (1990-1992). On these vehicles, adjust the BCM Override value "BS08". To do this, use the warmer/cooler button on the CCDIC to decrease the BCM override value "BS08" which is displayed when you enter the system by two(2). When the desired number is displayed on the CCDIC, it must be stored by holding the "Elapsed Time" and "Fuel Used" buttons until the new value flashes on and off. When it flashes on and off, the new value has been stored.
    • 1991 Eldorado and Seville with Computer Command Ride (CCR): Refer to the Service Manual page 8D-12. Set the BCM override value BS09 to 0 by using the warmer and cooler buttons. Store this value by pressing the Econ button on the climate control panel and the Instant Econ button on the Fuel Data/Drivers Information Center for about five seconds. The new value will be stored even through the indicator does not flash. Remove the key from the ignition. Disconnect both battery cables from the battery. When both cables have been disconnected, touch the ends of the cables together and hold for five seconds. This will discharge the capacitors in the system and allow the system to perform properly when the battery cables are reconnected. Advise the customer they will have to reset all radio stations and clock.
    • 1993 Eldorado and Seville with Speed Sensitive Suspension and 4.9L Engine Only: Refer to page 8A-43-6 in the 1992 Eldorado Seville Service Manual.
    o Cut Circuit 1020 (PINK)
    o Attach the IPC side of circuit 1020 to relay pin 87A
    o Attach the module side of circuit 1020 to relay pin 86
    o Run a ground wire to relay pin 30
    o Run a wire from a switched ignition (hot in run) source to relay pin 85.
    • 1991-1993 DeVille with Computer Command Ride (CCR): Refer to the Service Manual, page 8A-43-0. Cut Circuit 1300 (Dark Green wire) at the CCR module (Pin C15) to disable the indicator lamp. Tape the wires back into the harness to prevent shorting to other components.
    • 1994-1995 DeVille with Speed Sensitive Suspension (SSS) and 4.9L Engines ONLY: Refer to the 1994 Eldorado, Seville, DeVille Service Manual, page 8A-43-14:
    o Locate and cut circuit 370 (RED)
    o Attach the IPC side of circuit 370 to pin 87A of the relay
    o Attach the module side of circuit 370 to pin 86 of the relay
    o Run a ground wire to relay pin 30
    o Run a wire from a switched ignition (hot in run) source to relay pin 85.
    • The following part numbers are required to make the correction on the 1993 Eldorado/Seville and the 1994-1995 DeVille:

    1993 Eldorado and Seville with Speed Sensitive Suspension and 4.9L Engine Only: Refer to page 8A-43-6 in the 1992 Eldorado Seville Service Manual.
    o Cut Circuit 1020 (PINK)
    o Attach the IPC side of circuit 1020 to relay pin 87A
    o Attach the module side of circuit 1020 to relay pin 86
    o Run a ground wire to relay pin 30
    o Run a wire from a switched ignition (hot in run) source to relay pin 85.

    this works, and on mine I taped the brown wire for pin 85.....No more light

    Service manuals are available from time to time on Ebay. You don't need it for this if you follow directions carefully.

    You can buy the relay (P/N 12193601) and the connector(P/N15306045) at www.gmpartsdirect.com .

    The module you are looking for is mounted on the rear seat support, lower right, right of module marked Bosch, lower right side, accessible from the trunk. It is about 5" X 4" with a connector on the bottom.

    Following the instructions previously posted, you will identify which pins on the relay correspond to the wires on the connector/socket. The relay is plainly marked as to pin identity. The socket has extra connections for other uses so just strip the ends of the wires you will be using.

    You will find the pink wire coming out of the connector on the module. Cut it at a convenient place. You will wire pin 86 to the section of pink wire going to the module. You will wire pin 87A to the other section of pink wire.

    You will locate the solid brown wire and splice the wire from pin 85 into it.

    You will run the wire from pin 30 to a good ground. I used on of the bolts holding the Bosch module to the seat support.

    That should do it.

    When I did mine I soldered the connections and used shrink tubing and it has held fine for about 8 or 10 years.

    FWIW
    YMMV

    I know how to change the value, but How you open the BCM window to monitor the value as it changes.

    This thread has been dead for 4 years, better off starting your own in the Seville forums.

    Your Seville has passive suspension. What are you trying to do?
