Installing Passive Struts (Non-Electronic)

Bulletin No.: 00-03-11-001A

PROCEDURE TO DISABLE ILLUMINATION OF SERVICE INDICATOR AFTER THE INSTALLATION OF PASSIVE STRUTS/SHOCKS
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.

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 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 shock 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.

I have the wireing diagram and the relay info needed to turn off the Service ride control message but I am unable to post jpgs or links at this time due to website security, I will look for other ways to post this data for you.
