RED UFO

I have only owned my C5 for a couple of months so I am still learning about it. When I use the remote to lock the doors I push it twice. I am expecting to hear a beep. I get no beep. Is this normal? If it isnt where should I look for the problem?

I do not have a FSM yet.

Hey bud,

Press the options button on your car and you can adjust whether or not you'd like the horn to beep/lights to flash etc.. You press it and wait a second, then press it and scroll through. I'm pretty sure that the "reset" button is the one that turns it "on/off".

You have to program it to do that.

Perhaps this will help (from 2000 owner's manual, but should apply to your 1999):

Arming the System
Use one of the two following items listed here to arm
the system:

Press the LOCK button on the remote keyless
entry transmitter.

Open the door. (The SECURITY light should flash.)
Lock the door with the power door lock switch.
The SECURITY light will stop flashing and stay on.
Close the door. The SECURITY light should go off.
Testing the Alarm
Use the following to test the system:
1. Make sure the hatch/trunk lid is latched.
2. Lower a window on the door.
3. Manually arm the system.
4. Close the doors and wait 15 seconds.
5. Reach through the open window and manually
unlock the driver’s door.
6. Open the door. The alarm should sound.
7. Turn off the alarm.
If the alarm is inoperative, check to see if the horn
works. If not, check the horn fuse. See “Fuses and
Circuit Breakers” in the Index. If the horn works, but the
alarm doesn’t go off, see your dealer.
Disarming the System
Always use your key or the remote keyless entry
transmitter to unlock a door. Unlocking a door any other
way will set off the alarm. If your alarm sounds,
listed below are the ways you can disarm it:

Unlock the driver’s door with your key.

Put the key in the ignition.

Press the UNLOCK button on the remote keyless
entry transmitter.
Now, if a door or the hatch/trunk lid is opened without
the key or the remote keyless entry transmitter, the
alarm will go off. Your horn will sound for two minutes,
then it will go off to save battery power. And, your
vehicle won’t start.
The theft-deterrent system won’t arm if you lock the
driver’s door with a key, the manual door lock, or if you
use the power door lock after the doors are closed.
If your passenger stays in the vehicle when you leave
with the keys, have the passenger lock the vehicle after
the doors are closed. This way the alarm won’t arm,
and your passenger won’t set it off.

and from the DIC information within the owner's manual:

Lock and Arm
Press the OPTIONS button until LOCK & ARM
appears on the display, then use the RESET button to
page through the following selections:

LOCK & ARM - OFF

LOCK & ARM - HORN ONLY

LOCK & ARM - LIGHTS ONLY

LOCK & ARM - HORN & LIGHTS
If you choose LOCK & ARM - OFF, you will receive
no security feedback when locking or unlocking
your vehicle.
If you choose LOCK & ARM - HORN ONLY, only the
horn will chirp to let you know when your alarm system
has armed when locking your vehicle.
If you choose LOCK & ARM - LIGHTS ONLY,
only your exterior lamps will flash to let you know
when your alarm system has armed when locking
your vehicle.
If you choose LOCK & ARM - HORN & LIGHTS,
the horn will chirp and the exterior lamps will flash
briefly to let you know the system has armed when
locking your vehicle.
Alarm
Press the OPTIONS button until ALARM appears on
the display, then use the RESET button to page through
the following selections:

ALARM-HORN

ALARM HORN & LIGHTS
If you choose ALARM-HORN, the horn will sound
during an alarm.
If you choose ALARM HORN & LIGHTS, the horn
will sound and the interior and exterior lamps will flash
during an alarm.

Thank you

I have the owners manual. I don't have the Factory Service Manual yet. I do have the FSM for my 91. I plan to buy the 2003 FSM the funds are there.

RED UFO

Thanks,

I will put this PDF on my computer for quick reference.

The owners manual would have answered your original question.....

RED UFO

Point taken.

It just never accurred to me that it would be a selectable feature.

00Corvette

It's cool man, you said you've only had the car for a couple weeks. Most cars don't have anywhere near the features of a C5 as far as the DIC goes.

The DIC is your little driver information center there below your speedo/tach that lets you adjust all that crap.

Another cool thing that I don't think you'll find in the owners manual.

Press and hold number 4 on the right of the instrument cluster, simultaneously press number 1 four times while holding number 4. You will enter diagnostic mode. This is basically meaning that you can check and see what the problem is any time there is a trouble code/check engine light on in your car.

Bill Curlee

You don't need the service manual to set up the memory and IPC functions. There in there but,,,,, the owners manual is your friend in this case. Have you considered the ELECTRONIC version of the service manual?

Its a DVD/on line service manual that covers ALL GM from 1995 to 2005.

There are a couple of people on the forum and on line that sell them and there very reasonable

Bill Curlee

This might help understand the DTC and code reading:

READING YOUR Engine Diagnostic Trouble Codes (DTC)

This procedure should be carried out any time you experience a problem with your C5. Most inexpensive store bought aftermarket code readers will ONLY read power train DTC’s. Reading the DTC’s with the C5 built in code reader will allow you to read ALL the modules in the vehicle.

The Diagnostic Display Mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the RESET button to turn off any warning messages. (i.e. door open, trunk open ect)
3) Press and hold the OPTIONS button
4) While holding OPTIONS, press FUEL button four times within a 10 -second period.

Initially, the on-board diagnostics go into an Automatic Mode which will cycle through each module and shows diagnostic codes in a pre-set sequence: PCM - TCS - RTD - BCM - IPC - RADIO - HVAC - LDCM - RDCM - SCM - RFA. All codes will be displayed for each module. ( i.e. PCM = 4 codes) If none are present in a given module, you will see No More Codes on the display.

There are two types of diagnostic codes, Current and History designated with a letter suffix, “C” or “H”. A current code indicates a malfunction is present in the module displaying data. A history code indicates a problem existed sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it's potential evidence of a previous problem, now resolved, that was not removed by clearing the codes. More likely it's an indication of an intermittent malfunction.

Intermittent codes are the most challenging of the diagnostics. An intermittent code may have happened once, may have happened more than once but is inconsistent or may be happening on a regular basis but not at the time the codes are displayed. History codes can also be caused by a current malfunction in a system that is not operating at the time codes are displayed. An example is the rear window defogger which doesn't operate until the Body Control Module detects engine rpm. For history codes set by a module that does not operate with the key on and engine off, a special diagnostic tool called a Scan Tester is necessary to properly diagnose the malfunction.

Once the system has displayed all modules, it goes into the manual mode which allows selection of each module using combinations of Driver Information Center buttons. Manual mode can also be entered during the automatic sequence by pressing any button except E/M. Once the display shows Manual Diagnostics, select a module by pressing the OPTIONS button to go forward or the TRIP button to go back. Once a module is selected, a code is displayed, and if more than one are present; press GAGES to go forward or FUEL to go back.
To exit the diagnostic mode at any time, press E/M. If you want to erase codes in a given module, press RESET To reset the codes once in manual mode, press and hold RESET until it displays NO CODES Press OPTIONS to go to the next module. Repeat the steps until you have reset the codes in all the computer modules.
NOTE!! Only reset the codes IF you want to - it is NOT necessary to do this. Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory. If you clear the code/s, and extinguish the Check Engine Light, your emissions status ready will NOT allow you to pass an emissions test until you have completed the required driving cycles. There are a few body module DTC’s that if set will prevent the module from operating properly. Once the DTC is cleared, the module will return to full function. This is not true for power train DTCs.

If you have never read and cleared your codes, there will probably be a lot of old history DTCs. It is recommended that you clear your codes and see if any come back during a driving cycle. Those are the ones that you need to concentrate on diagnosing.

Once you have the codes, the next question is: What to do with the information?
First, consult the factory service manual. Any serious C5 Do-It-Yourself owner should invest in the Corvette Service Manual of the appropriate model year. The Service Manual is really a requirement if you want to understand and work on your C5.

NOTE and a WARNING. You can read the DTCs while the engine is running. I pull mine up all the time while driving.
WARNING. Don’t become distracted while reading DTCs while your driving and cause an accident!!!!! Use common sense and drive safe.

These are some very good C5 Diagnostic Trouble Code (DTC) explanation web sites!!! They also explain how to read the DTCs

Here are some very good sites that explain what DTC mean:

http://www.gearchatter.com/viewtopic11755.php

http://www.obd-codes.com/trouble_cod...d-ii-codes.php

Make sure to include the H or C suffix when you post your DTCs!!

Friendly suggestion, read the owners manual cover to cover. There is a lot of good information in there.

Where is the alarm.... is ther a way ioto adjust the sensitivity?

Bill Curlee

The alarm system consist of the following components:

Horns
Door, trunk switches
BCM
Theft deterrent ignition system

Theres NOT anything to adjust other than what will honk, flash or blink light wise when the alarm sounds. If you open a door or the trunk or cause something to wake the BCM from the sleep mode IE drawing current to turn on something) the alarm will sound if you have it enabled in the options.

The ONLY thing that it doesn't have is a shock or sonic sensor but, there are companies that can add that ability to our C5 system.

Thanks Bill.. I was assumming that it was like the F-Body Alarm system...

Corvette Maniac

I know this is an older topic, but is it possible that I don't have the ALARM option in the DIC?? And I can't select horn & lights for locking/unlocking :S

Is it possible the previous owner or dealer turned the alarm off?? If I open the hatch or door, the horn sounds tho... Very strange to me... :S

Bill Curlee

The alarm is not an OPTION and it can not be disabled. Its part of the BCM and you can interface how it alerts" Lights/ Horn/ LIGHTS and HORN".

Even if you turn everything OFF, the security system will still disable the car.
