Service Air Bag Message displayed

[lovemycadi]

I am a new user here and would like info from someone other than the people who last worked on my car. Feeling very "gun shy".

My 1999 Cadillac De Ville is displaying Service Air Bag message as of last night. I just got the car back from having the cooling system

pressure tested and the following done - new Radiator, Water pump, and Coolant reservoir, and 2 new struts. 

i will greatly appreciate all information received.

[OldCadTech]

If you would please pull the codes and write them down here that would be very helpful.

Hold the OFF & WARMER buttons down for approx 3-4 seconds when the WOW display stops (you'll know it) use the warmer button for yes cooler button for no. The DIC will display ALL DTCs? push the warmer button and write them all down. You may have to cycle through them a couple of times as they go pretty fast.

Post them here....

Thank you for your reply. 

Ok Here is what I got from the display.

CURRENT CODES

ACM B1983   IPC  B1983   PCM B1983   ACM B1312   SDM B1327   

HISTORY

IPC B1552   PCM B0603   PZM B1552   PZM B1558    PCM B2471  SDM U1255   SDM B1148   

 

NO TCS, NO IRC, NO RFA

 

Now the car will not start, just get clicking sound.

Something is wrong with the codes you jotted down.  I find it helpful to use the video on my smartphone and tape them as they come up.  Post them here exactly.

Just I guess, but my guess is that they left the air bag collision discriminator unplugged by the radiator.  

Also look at your high side temperature sensor against the firewall to see if it is disconnected based on the B1312 current

[OldCadTech]

Sounds like the battery is low, charge the battery.

[lovemycadi]

BodybyFisher,

Thank you for your reply.

I did use my phone to record the codes as there were so many and they came quite fast. There is an error in the list,

PCM B1983  should have been PZM B1983,  sorry for the error. 

I am a senior female, and have no clue what I would be looking at, I can check oil and add some, that is about it. 

 

OldCadTech

Thank you!

Unfortunately, my charger is in my other car, which is in the shop. I have no transportation until it is finished possibly late Monday or early Tuesday.

The battery is less than a year old.  

[BodybyFisher]

B1983 Device Power Circuit Low

A battery is one year old can be bad from a bad cell, internal short or dirty or corroded cable connections.  It needs checking.

Look very closely at the codes.  I just worked on a 2000 that had an air bag message current and it had this code:

A current code B0041.  It means > B0041 LF/Driver Side Deployment Loop Open.  On a 2000 it is related to the LF collision sensor.  Not sure if that related to a 99 regarding side impact.  

If your 99 is the same as my 96, 97 and 98 there is a collision sensor that needs removing when the radiator is removed and since you had your radiator removed, it is where I would look.  BUT, you are not showing codes for SIR, but I didnt see you state NO SIR codes.  That is why I want you to look closer and run your codes again.  

@OldCadTech picked up the low battery / voltage code and that can create lots of false codes so if your battery is weak or bad look there first.  I am not a fan of jumping these cars by the way and would never jump mine or jump anyone else.  

If you are getting an SIR message you should be getting an SIR code if the battery is good

ONE CAUTION!!!!  DO NOT PLUG IN A COLLISION SENSOR WITH THE BATTERY CONNECTED, DISCONNECT THE BATTERY, NEGATIVE CABLE!!!! WE DO NOT WANT AN ACCIDENTAL DEPLOYMENT.

Sounds like the repair shop needs to re-check their work.

Call them and be the squeaky wheel

I just edited by prior post, to let the OP know that a one year old battery can still be the problem. 

[OldCadTech]

LOL, I was about to do the same edit, you beat me to it.

A one year old bad battery still has warranty on it

[lovemycadi]

Thank you so much BodybyFisher and OldCadTech. 

When I get my other car back from the shop,  There is a trickle charger in that car, would it be ok to use that, or should I call AAA and have it towed to shop? 

I double checked the video, there was one message it displayed that I did not know what to do about it was PCM? 

Thank you again for your help. I will get a new battery and return the one in the car somehow. 

[lovemycadi]

I tried to attach the video but it is too big.

[OldCadTech]

I would call the repair shop and ask them;

1) Why did the SRS/Air Bag light come on after they worked on the cooling system?

1a) Did they disconnect the forward sensor? If so, did they reconnect it?

1b) Did they disable the SRS/Air Bag system prior to working on the vehicle? (They should have)

2) Why did my one year old battery die after they worked on the cooling system?

2a) Did the battery go dead while they were working on the vehicle?

2b) Did they remove the battery to facilitate removal of the radiator or any other replaced items?

3) Would they please tow the vehicle to their facility at their expense and recheck their work?

3a) Would they like you to send the vehicle to a Cadillac dealer for diagnostics and they pay for the diagnostic time?

If the battery is dead, the codes are irrelevant at this point. It needs a good battery source first!!

They could be responsible for the battery problem, see how the conversation goes first before replacing the battery.

[OldCadTech]

Also, as a side note @lovemycadi 

I think the side impact sensors are in the area of the struts which were replaced, isn't that a coincidence ?????

Also, the coolant reservoir is very difficult if not impossible to remove without evacuating and recharging the A/C system, another coincidence ????

Send it to my email address at reconsultant3@yahoo.com.  i can accept a pretty big file there.

How convenient lol. ....

My Dad used to say, these mechanics wouldn't make a patch on a mechanics arse lol

I used to be slow, but now I am half-fast.......

My GM service info is showing some different info...

1148- Passenger side airbag malfunction.

1327- Device power low (below 9.5v)

The 1327 will cause a 1255.

1255- disable state of health code.

The side impact sensors are in the doors.

 

 

[lovemycadi]

Thank you both so very much. I will use all of the information you have shared when talking to the people who serviced my Cadi.

I used to get very good service at the place I take my cars. I have not been real confident in their work since they changed mgt 2 years ago. One of the owners managed the shop, but he moved to one of their other shops which is quite a bit farther away. 

I recently had a brake job redone at the shop the old mgr moved to - my almost new brakes were replaced under warranty by his shop. He assured me the guys at the other shop, where I usually took my car would be able to handle the pressure test and any work needed. 

There are a lot of coincidences here, aren't there?

Sending the video to you BodyByFisher.

I am very thankful for your help.

 

[lovemycadi]

Logan,

Thank you for the response, I really appreciate all the help I am getting. 

I will be contacting the manager of the shop that did the work as well as the owner who moved to another shop.

Good pickup Logan, I missed that.

[OldCadTech]

@Logan You're probably correct, I must have my cars confused. I was thinking Cadillac had a three forward sensor setup for off angle hits, that probably proceeded 99 model year by a few years tho. 

[lovemycadi]

Well, this is a final thanks to all of you for your help. So here is how my saga is playing out so far.

I made the shop pay for a tow to the garage, as they did not want to pay for a Cadillac service center to check their work. Tow came at 7:30 Monday night, I went with him because my other car was ready, So I paid that bill and drove home, and a whole new problem popped up with that car. 

The shop was kinda surprised at all the info I had - thanks to you - and agreed to recheck their work and diagnose the battery issue.

So, I got a call this am telling me they found no reason for the Air Bag Service message, and the battery checked out OK. I told them it did not make sense to me. Especially since one of the codes was a result of low power.  Anyway, because of the new issue on the other car, I had to go back with it. They told me all they did to check out the battery, and were satisfied it was OK. So, I left the keys to the car I drove in, picked up the Cadi keys and went out to leave. Nope! Car did not start, tried to turn over and that clicking sound again. I went in and told the service manager Cadi would not start, he almost fell on the floor. He got  a mechanic to come out with a battery diagnostic device,  When they came out with the device of course it started on first try. they ran diagnostics and after the 3rd or 4th test (load test) a problem showed up, 111 volts not the 600 they were expecting to see on one of the readings. They said "THE BATTERY IS BAD!"  almost in unison. I ALMOST laughed, but it was not funny. So, two hours later after going to get new battery and having them put it in, and returning the old battery to the store to get my full credit for the 8 month old battery. I am home, unable to relax worrying about what the !***! is going on with the other car. I am just trying to get it ready to sell.  

SHOT IN THE DARK!!!  Do you know anybody who knows about the Exhaust system sensors on a 2004 Lincoln LSE ????? (that is what the check engine codes that are popping up are related to).

Sorry, if this was boring, but I wanted you to know the rest of the story, as far as the Cadi is concerned. 

Thank you for sharing with me.

[BodybyFisher]

When you say exhaust system sensors, I assume you are speaking of O2 sensors.  Can you provide the codes to us?   By the way, OBD2 codes are the same for all manufacturers for the most part..   If you click, OBD2 in my signature below, you can look up codes, you will be looking at P or Powertrain codes.  OR you can post them here and we can help.

[OldCadTech]

Did the AirBag light go out after the battery replace?

[lovemycadi]

Old Cad Tech,

Yes, they charged the old battery and when it was charged, they said all the codes stopped coming up as current.
