Sorry, I can't find codes

[What job]

Hello forum.

Sorry to be asking this in this part of the forum. I tried but, I can not find the listing for code BO20 or Code BO21 on this 91 seville. Am I reading the codes wrong? I checked twice and the codes are what looks to be BO20 and BO21. I have checked in two differant places on the web and neither list these two codes.

I also looked in the FAQ but found nothing that would help. Any ideas?

Thanks folks for any input.

[Cadillac Jim]

Here's what I find in my database:

S020 Left Rear Damper Solenoid Valve Short to B+

S021 Left Rear Damper Solenoid Valve Short to Ground/Open

P020 (E020) Open Fuel Pump Circuit

B1021 Driver Deployment Loop Resistance High (Air bag code, OBD II)

I don't think that any of these is likely to be the same as the OBD I B020/B021, and my database starts the Body codes at B110. You're going to need a 1991 FSM, or for someone with one to step in.

[Dominator]

the s021 service code that I have found applies to the 93 Allante and it does refer to the l/r damper soleniod valve-short to ground. Looking at the manual now

[Cadillac Jim]

S021 Left Rear Damper Solenoid Valve Short to Ground/Open

Most likely, the connector to the left rear shock is loose or off.

[Dominator]

S021 Left Rear Damper Solenoid Valve Short to Ground/Open

Most likely, the connector to the left rear shock is loose or off.

That's not the case with my Allante Jims...without probing every possible wire, harness etc I can't seem to find an easy fix. It's a huge nuisance to constantly have the message come up on my display to service ride control.

[Cadillac Jim]

Dominator -- the next step is to unplug the left rear shock and check the shock connectors for continuity with an ohmmeter. Can you do that? If the shock checks good, then you need to look harder at the connector and terminals. It's probably the connector or the shock itself. Barring that, then check the connector to the PZM on the other end of that wire. Then, you can check the continuity of the wires from the PZM to the shock connector...

Yup...sure can do that...I'll keep you posted

OK...here's the scoop...After following the tree in the manual it says that I must replace the damper. Now the question is...where the hell is that located? Is it the solenoid mounted on the frame? Or is it in the position sensor itself...Or am I just plain stupid and it's the shock itself? Of course everything that I read refers to the shock as a shock and not a damper. I have found nothing in the manual that points out where it is located.

[dmk9561]

I've heard shocks referred to as dampers before, so I'm sure that's what it is.

[Cadillac Jim]

It's the rear shocks. To get the price, you need the suspension option code, which will be in the spare tire compartment somewhere. People here have had good luck with Rock Auto. Monroe seems to be OEM and is a little less than AC/Delco, so Monroe is OK. I don't know about others.

There may be people who chime in on how to disable parts of your suspension to get a cheaper shock than OEM replacement. It's your car, but I think it's a bad idea to cheap out maintenance of my Cadillac. What do you say if you sell or trade the car, or if someone has the car inspected and finds that leveling/RSS/Stabilitrak has been compromised or disabled? Then. there's the performance and safety perspective. Your car, your choice, though.

When "automatic" shocks go bad, the computer turns them to "manual" default mode (stiff one). I would leave the shocks alone and just disable the service computer ride message. Check this out:

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.

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.

once again defeated..this being a 93 the info you supplied is not applicable.

After verifying that the shocks ere bad with a resistance check, I would get the suspension code from the options sticker (or, failing that, from the dealer with the VIN number) and get OEM Monroe shocks for that suspension code.
