Service SSS Light on

[bob393]

Does anyone know how to reset the check speed sensitive suspension light on the 1993 Deville.

The light came on when I unplugged one of the front struts and now it will not go out.

Simultaneously press and hold the OFF & WARMER buttons to enter the onboard diagnostics. After the codes have been displayed, use the HIGH fan button to answer YES and the LOW FAN button to answer NO. Answer yes to CLEAR CODES?.

[bob393]

Does it say clear codes or do I just go through the sequence?

I don't get a diagnostic code for the SSS.

You did plug the terminal back in good didn't you? Was it corroded or dirty? If it was, you might try to unplug it again and clean it up. When all else fails unhook the battery for a few minutes to clear it out.

Which code was it? Some codes cannot be reset by unplugging the battery, or even from the DIC controls, and require a Tech II or the equivalent (i.e. a $200 PC-based code reader with full Tech II capability). I thought that the only ones like that were air bag codes but I don't have any definitive reference material on this.

Pull all the codes and post them here. Here's how:

Well I tried the internal reader and when I pressed high I got a 000 display but it didn't clear the check SSS light. The only code that is displayed during the check was F47, if I remember and that's an air conditioning freon code and that code is correct, it is low on freon.

I may not have been specific enough, the service SSS light is not a code but a warning light that showed up in the information display at the bottom of the dash, left side of the wheel, the panel to the right of the wheel is where the service air conditioning light comes on and off intermittently. Because the AC light displayed a diagnostic cone I assumed that the service SSS would also.

I will check again but I think I plugged in the strut wire in tightly, I will check it again when it stops snowing.

I would love any more thoughts you may have.

Thanks

If the SES light is on, there is a DTC stored.

[bob393]

Ranger I don't doubt that there is a DTC code stored,

but the only code displayed is an F47 and that clears when I use the high fan button.

The service SSS light comes on when I turn the key on, I think that's the self test for the bulb, then goes out,

and than comes back on about 10 sec after I start the car and stays on.

Perhaps there is something really wrong with the system? It just seems strange that it came on

after I unplugged one of the front strut wires and plugged it back in.

I just ran the on-board diagnostics again and this is exactly what I got after simultaneously pressed and held the OFF & WARMER buttons:

888 F F47 FF F47 70 Than I pressed the High fan button and got E95 I pressed it again and got E00.

Ant thoughts?

P047 (E047) ................................................. IPC - PCM Data Problem

I think an "F" code might be history, but I am not positive. Someone will correct me if I am wrong, but both are the same DTC as listed above.

[bob393]

I checked the connection on the strut plug today, It's tight with no corrosion.

I also disconnected the battery for five or ten minuets while I cleaned and

tightened the body ground lug by the battery.

The light is still on!

Help, please.

[Ranger]

I'm out of ideas.

The Check Engine light is supposed to be on with the key on and the engine off. That's the bulb check for that light.

When you press the OFF and WARMER Buttons, the first thing that happens is the segment (bulb, LED and plasma display) test. Everything should come on. If you have a 24-character display and are seeing things like "888 F F47 FF F47 70" then there may be a problem. If you only have three seven-segment digits and the display is "888" then "F" then "F47" etc. then you are OK.

The E047 code is a network code. I would check the purple wire (if the network wire is purple in the 1993 model year). If you are having consistent network communication problems between the IPM and the PCM that will set the code. I don't have any F codes in my OBD I listing; could this be a P? My listing of OBD I codes includes B, L, I, T, R, A, S, and P or E codes. I believe that OBD I has a suffix of H for History and C for Current.

[bob393]

I know all the lights come on when you turn the key on for a self test before you start the engine.

I have a three digit display separated by periods. 8.8.8. so all the segments are working.

The F is really an F and not a P. I have no E047 code, that would be one digit to many for my display.

I just checked the cods and a new E98 has creped in, still has the F47

code which I was told was low freon in the AC, which is true.

I can tell you that the car starts, runs and drives fine, perhaps a bit stiff in the suspension which makes me think

that perhaps the SSS light is correct if the system defaults to full stiff, but it's fine.

Thanks for the help, this is really killing me!

I am stumped.

A couple of other things to check.

If the system senses a "dive" condition (heavy braking), or a "lift" condition (hard acceleration) it will switch to firm mode. Stating in either position for an unusual period of time will set the error lamp.

Check:

• Does your car sit, and drive level?
• When you worked on your car, did you bend a link, dislodge a link or wire connection, disconnect a Ride Height module?
• Have you been doing anything in the trunk, that may have bumped or dislodged any wire connections? (Thats where the computer ride control module is.)
• Look at the fuses in the engine compartment (C7?) a 10 amp fuse, might be abbreviated for SSS or RSS.

George, thanks.

I will check those items when it stops raining, lousy weather in the Northeast.

It could be riding a bit tail high as the headlights seem a bit low all of a sudden.

I was snooping around the trunk because I was told there was a fuse block for the

trunk motor, I never found it but who knows I may have disturbed something.

I'll look soon.

E98 means you have probably shifted from park or neutral into drive or reverse with an engine rpm 600 greater than desired. The harsh shift most likley was driver induced. Basically your car is telling you that you shifted it too rough.

[bob393]

Well that is true if it counts when you first start the car and the high idle is engaged.

Otherwise no way.

But these codes are not resetting!

[bob393]

In the final analysis I would have to say the car rides and sits level.

Nothing under the car is disconnected, loose or bent, everything seems to be connected.

All the wires in the trunk are connected.

The engine compartment fuses are good, and the interior fuses are good.

I'm at my wits end on this one?

Another thing that seems to be wrong is the radio clock stays on all the time, I don't remember that.

[bob393]

Another symptom seems to be that the battery will go dead after three days of sitting.

When I drive the car every day it's fine but let it sit, dead as a door nail.

I don't know if that's related but it's true.

[Ranger]

You have a parasitic drain. Pull the battery cable and place a 12v test lamp in line (between the cable and the terminal). The light will probably illuminate. Start pulling fuses till it goes out. Then you will know what circuit or component is causing the drain.

This could be what is causing your battery to go dead.

How old is your battery? If it is due to be changed, do so. A low battery will cause all kinds of electrical gremlins. I would unhook the battery for a while and see if that clears out things. Check the grounds and clean the terminals. Make sure they are good and tight also. As far as the F47 code, it means that your freon is low. The FF in front of the code means it is a "current" code. As far as the battery drain, check the visors after dark, check the glove box light, check the trunk light to see if it goes off.

My 1993 Sixty Special displayed its "Service SSS" light about a year ago for a couple of days. But it went out on its own. Now, it has come on again and this time it has stayed on. I haven't done anything to cause it as far as I know and I can't tell any difference in the car so I am just going to ignore it. I wish I did know what is causing it, though. My self-leveling in the rear works perfectly so I don't think that is the cause.
