Beeping upon startup

[SoulSoak]

This has always happen but I'm just now making a thread (curious). When I enter my '03 LS8 sport and turn the key all the way before starting and the instrument lights come on, I get 6 beeps. Then I start the car and go to work. However I've noticed if I stop at the gas station to grab a drink or snack and turn the car off, when I go to start it again I get only 3 beeps. Sometimes 4, and sometimes none. But always 6 beeps at a cold start.

Just curious as to what these beeps mean, thanks guys and God bless.

Are you sure this is from the beeper in the cluster? Might it be some aftermarket device instead? Do you have a remote start or extra alarm installed?

 

[G-RELL]

the same Chime as if you left the lights on and the car off? (door open)??? sounds aftermarket

 

[LS4me]

IIRC, there is an "alarm" if the battery was disconnected for an extended period of time or someone tampered with the mileage.

 

[SoulSoak]

No aftermarket alarm or starter. Beeping is the same chime as the repetitive chime you get with door open while key is in ignition(just a slower extended chime).

 

[RigsLS]

Audible alarm possibly indicating some light bulbs out on dash, on start, for the first 5 seconds, does the airbag light illuminate ?
Might be as simple as a dash bulb out alert. On the Message center when you run a Status check, everything comes back as OK ?
Does it do it with or without the seatbelt clicked in on startup ?

 

[Andrizzle]

Side note. Is there a way to disable the chime that reminds you to take the keys out of ignition with door open?

I almost shot myself the other night replacing window regulator clips.

 

[SoulSoak]

Okay so I buckled my seatbelt prior to turning the key and I get no beeping/chime. However, when I turn the key all the way prior to starting, all the instrument lights come on for a few seconds, then they all turn off except the battery, Engine and oil lights.

 

[joegr]

If by "all" you really mean most, this is correct operation. It's often called "prove out," and it allows you to verify that the warning indicators are working. You shouldn't see lights like the turn signals, high beam, and so on do this.

Correct I meant "most", thanks Joe.

Start the car and look on the instrument cluster and see if this light comes on for 5 seconds and then goes out.




It should just come on solid for 5 seconds and not blink thereafter, does it ?

The AirBag Readiness should momentarily illuminate when the ignition is turned to the RUN position. I suspect the SRS system may have a fault.

The wiring under the seats could be damaged, there are occupant detection sensors in the seats used to determine deployment of the airbag.


Did you ever replace the clock spring in this LS ?

I've never replaced the clock spring, and yes that particular light stays on for 5 seconds then shuts off. The battery, oil, and engine picture lights stay on however.

 

[RigsLS]

Hmmm strange cuz the 5 beep series is a warning that it's unable to tell you something via a bulb in the cluster as far as I read.
common for the Restraint system. (SRS)


Battery, Oil & Engine lights should stay on while in the RUN position, they should go out when started though.


What about #9 in the above picture, the seatbelt one, same thing ?


----EDIT: what I meant is, it actually come on before it goes out.

Sometimes used car dealerships pull the bulbs rather than fix things and then the system gives the audible alert because it's unable to indicate a fault via a bulb.

 

[RigsLS]

Just an idea ... for "how they say" funzies. (???)

you know the 1/2 driver preference settings on the drivers side door.

try adjusting your tilt steering up and down and your seat back and forth and reset setting #1, hold SET and push 1 (or the other way around, can't recall)

try resetting that ... never know.


if not, personally myself, I would try a hard reboot on the PCM via the disconnecting of the battery cables for a while, reset the whole thing, see what she does.

 

[1LoudLS]

as bigrig mentioned, the The battery, oil, and engine lights should stay on when the key is turned to the "RUN" position and the engine is not running (either hasnt been started or engine died)

the battery light is on because the voltage of just the battery is too low for normal operation with the motor running and the car thinks there is something wrong with the charging system. the oil light is on because the car is not seeing enough oil pressure (because the motor is not running and pumping oil) and that would be a major problem to a running engine. the engine light is on because the key is in the RUN position and the car is expecting to "see" a RUNning motor and is telling you that there is a problem and that you need to check the engine. all of the other lights that turned on will still shut off (normally) because the systems passed the test and are working.

I almost shot myself the other night replacing window regulator clips.

Couldn't you just pull the key out 1/3 of the way in the cylinder? (I think that would have shut it up, will have to check myself)


There's only the Fasten Seat Belt enable/disable, "Belt minder chime" option.



and Lock Chirp ON/OFF ... but that's not an interior chime.

 

[Andrizzle]

Well I needed window operation for the regulators.

 

[RigsLS]

True, Key in/out when needed.

I'm sure if you were to open it all up, in there somewhere, it must be possible to either cancel it out or desolder the damn thing.
could very well with a tune be programmed for ON/OFF on the options. must be possible, I've seen instruction sets on the testing tools for ON/OFF options.

Has got to be possible to load a program with desired options tweaked.

 

[SoulSoak]

Just got out of work, haven't been able to respond until now. Yes Bigrig, my instrument lights seem to be functioning properly as of normal instrument response of a problem free LS. Also, ever since I've began buckling my seatbelt prior to inserting my key into the ignition, I've had no beeping/chime. And as of resetting the computer, I've had the battery disconnected for long periods of time when doing my LoC install to my factory head unit to accommodate my aftermarket subwoofer amplifier. So I'd assume it's been reset? But I don't know, thanks everyone for all the input, hope the dealer didn't pull bulbs on me.

 

[RigsLS]

Not sure what to tell ya, everything I've read on this beeping subject leads to a fault in the Supplemental Restraint System (SRS)



There does appear to be a Fuse/Relay involved in the above pic but it's not LS specific, we'd have to check.

If it is related to the SRS, it's important that it get corrected properly so as during an impact the airbags will in fact deploy.
The fact that it doesn't do it when you click the seatbelt tells logic thinking that it's related and could even be as simple as a cut wire under the seat.

You could of course go in the settings and do that disable seatbelt chime
... but that's not a fix, rather a band-aid solution and not even guaranteed it'll stop the fault alert.

Sounds like an expensive dealership repair.

If you do decide to check the wiring/connectors under the seat,
do be sure to disconnect the battery first as those airbags can go off in a hurry and knock you silly.

Additional info,


Restraints Control Module (RCM)

The restraints control module (RCM) is mounted on the center tunnel under the instrument panel. The RCM performs the following functions:

- signals the inflators to deploy the air bags in the event of a deployable crash.
- activates the belt retractor pretensioners to remove slack from the safety belt webbing.
- monitors the air bag supplemental restraint system (SRS) for faults.
- illuminates the air bag indicator if a fault is detected.
- flashes the air bag indicator to indicate the lamp fault code (LFC) detected.
- communicates the current or historical diagnostic trouble codes (DTCs) through the data link connector (DLC).
- signals the instrument cluster to activate a chime if the air bag indicator is not available and another SRS fault exists.
- contains an internal safing sensor which is not serviced separately.

The RCM monitors the SRS for possible faults. If a fault is detected while the ignition switch is in the RUN position, the RCM will illuminate the air bag indicator located in the instrument cluster.

When the ignition is cycled (turned off and then on), the air bag indicator will remain lit for six seconds and then go out. If an SRS fault exists, the air bag indicator will then flash the two-digit LFC associated with that fault. The air bag indicator will flash the LFC five times, then remain illuminated for the rest of the key cycle. The RCM will also communicate the current and historical DTCs through the data link connector (DLC), using the New Generation Star (NGS) Tester. If the air bag indicator does not function, and the system detects a fault condition, the RCM will signal the instrument cluster to activate an audible chime. The chime is a series of five sets of five tone bursts. If the chime is heard, the SRS and the air bag indicator require repair.

LFCs are prioritized. If two or more faults occur at the same time, the fault having the highest priority will be displayed first. After that fault has been corrected, the next highest priority fault will be displayed.

The RCM includes a backup power supply. This feature provides sufficient backup power to deploy the air bags and belt retractor pretensioners in the event that the ignition circuit is damaged in a collision before the safing and air bag sensors determine that an air bag deployment is required. The backup power supply will deplete its stored energy approximately one minute after the battery ground cable is disconnected.


Electrical System

The electrical system that supports the air bag supplemental restraint system (SRS):

- is powered from the battery through the ignition circuit.
- provides the electrical path from the restraints control module (RCM) to the SRS components.
- provides the electrical path from the RCM to the air bag indicator.
- provides the electrical path from the RCM to the data link connector (DLC).
- provides the electrical path from the RCM to the instrument cluster.

Sorry BigRigLS, but you are going way off in the wrong direction here. The five sets of five beeps from the cluster is well known to be the warning that the SRS has a problem and that the SRS light isn't working.
SoulSoak has confirmed that the SRS light is working, and that the source of the beeps was the initial seatbelt warning (six beeps, not 25 beeps). I (and I suspect you), get the same warning at startup if we haven't buckled the seat belt yet. Now that he is buckling his seat belt, he is no longer getting the warning. Let's not try to create a problem where there is none. The LS has enough actual problems.

 

[RigsLS]

Just reading all this SRS stuff in the workshop repair manual for GEN I and .... I wouldn't begin to f*ck with it, it's got deactivation and re-activation procedures in it for the sake of safety on the airbags, too complex, sensors and connectors everywhere. Requires special Restraint system diagnostic tools even to perform testing along with reading the Diagnostic Trouble Codes (DTCs).




Prove Out Procedure

Turn the ignition switch from the OFF to the RUN position and visually monitor the air bag indicator with the air bag modules or restraint system diagnostic tools installed. The air bag indicator will light continuously for approximately six seconds and then turn off. If an air bag supplemental restraint system (SRS) fault is present, the air bag indicator will either:

- fail to light.
- remain lit continuously.
- flash.

The flashing might not occur until approximately 30 seconds after the ignition switch has been turned from the OFF to the RUN position. This is the time required for the restraints control module (RCM) to complete the testing of the SRS. If the air bag indicator is inoperative and an SRS fault exists, a chime will sound in a pattern of five sets of five beeps. If this occurs, the air bag indicator will need to be repaired before diagnosis can continue.



... and I'm not even sure if you are getting "chime will sound in a pattern of five sets of five beeps" ?
Thought you mentioned, random beeps, sometimes 4, sometimes 5 ... might not be at all related if it's not in series of 5 X 5.

So it's just the normal ****ing seatbelt chime he's bitching about, are you for real ?

Egg on my face!






There's a procedure to disable the seat belt chime. it's in the OM.

I get the regular beeps when I start the car but also, from the radio it sounds like, I just started getting 3 beeps and the radio reads "all seats", anyone?
