Need Help With My 07 Nbs And A Dead Battery
Posted 15 February 2008 - 07:48 AM
I am having a weird issue with my 07 NBS crew cam Silverado and was hoping I could get some help. The truck is about 6 months old and has roughly 6k miles on it.
I drove it home from work last Friday and parked it in my garage. My wife went out of twon on Saturday so I was driving her car while she was gone because it got better gas mileage. I then got in it the next Wednesday (2 days ago) morning and the battery was dead. I did leave my radar detector plugged up to the cigarette lighter so I guess that drained the battery down. I went ahead and jump started it with my wifes car and drove it around the block and parked it back in the garage. I thought everything was back to normal. I then tried starting the truck that night (Wednesday) after work and it was dead again. I jump started it again and this time drove it around for about 15 minutes and it seemed fine. Then last night (Thursday) I tried starting it and the lights come on but it just clicks, not enough juice in the battery to start.
Is there something wrong with my truck or do I just need to drive it for longer then 15 minutes and that will charge the battery enough where letting it set for 24 hours will not drain the battery. That does not seem right.
Any comments from a mechanic or someone that might know would be appreciated.. I know its under warranty but don't want to waste my time going there if it just needs to be driven.
My wife will return home in the next couple of days and I will be beack to driving my truck on a daily basis, but it does not seem right for a truck to die after sitting for 24 hours in the garage. Is this the battery or something else causing this?
Thanks in advance.

THE SERVICE PROCEDURE IN THIS BULLETIN HAS BEEN REVISED TO ADDRESS VEHICLES WITHOUT A DRIVER INFORMATION CENTER (DIC) AND POWER DOOR LOCKS/WINDOWS, AND A CONDITION WHERE THE ODOMETER READING DISPLAYS METRIC UNITS INSTEAD OF ENGLISH UNITS.
TECHNICIANS MAY EXPERIENCE SLOW PERFORMANCE USING THE TIS2 WEB APPLICATION WHEN REPROGRAMMING THE VEHICLE TO CORRECT THE CONDITION. TECHNICIANS MAY NOTICE THE SLOWER APPLICATION PERFORMANCE FROM MID-MORNING UNTIL LATE AFTERNOON.
TO ASSIST IN IMPROVING PERFORMANCE AND REDUCE PROGRAMMING TIME, IT IS RECOMMENDED TO COMPLETE THE BULLETIN PROCEDURE ON CUSTOMER VEHICLES FIRST. VEHICLES IN INVENTORY SHOULD BE PROGRAMMED DURING OFF PEAK HOURS IF SLOW PERFORMANCE IS EXPERIENCED.
This bulletin provides a service procedure to reprogram the body control module (BCM). On these vehicles, and under certain conditions such as operating the radio with the engine off, the battery can become discharged, preventing engine start-up.
This service procedure should be completed as soon as possible on involved vehicles currently in dealer/retailer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.
A list of involved vehicles currently in dealer inventory is attached to the Administrative Message (US) or Dealer Communication (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS. Not all vehicles within the above breakpoints may be involved.
Important: Technicians may experience slow performance using the TIS2 web application when reprogramming the vehicle to correct the condition. Technicians may notice the slower application performance from mid-morning until late afternoon.
To assist in improving performance and reduce programming time, it is recommended to complete the bulletin procedure on customer vehicles first. Vehicles in inventory should be programmed during off peak hours if slow performance is experienced.
Important: The calibration numbers required for this service procedure are programmed into control modules via a Techline Tech 2® scan tool and the Techline Information System (TIS) terminal with the calibration update. Use TIS 2 Web version 2.0 for 2007 (available on 02/04/07) and on TIS DVD version 2.0/2007 or later, that was mailed to dealers on 02/14/2007. If you cannot access the calibration, call the Techline Customer Support Center at 1-800-828-6860 (English) or 1-800-503-3222 (French) and it will be provided.
Notice: Before reprogramming, please check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lights, interior lights, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if battery voltage guidelines are not observed.
The ignition switch must be in the proper position. The Tech 2® prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
Make certain all tool connections are secure, including the following components and circuits:
The RS-232 communication cable port
The connection at the data link connector (DLC)
The voltage supply circuits
DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date.
Tech 2 Pass-Thru Method for the Body Control Module (BCM)
Verify that there is a battery charge of 12 to 16 volts. The battery must be able to maintain a charge during programming. Use an additional jump battery if necessary.
If the vehicle will not start, test and charge the battery. Refer to SI for battery testing and charging information, if required.
If the battery will not hold a charge, replace the battery. Do NOT replace the battery unless it cant be charged or a leak and/or physical damage is present.
Connect the Tech 2 to the vehicle and the TIS terminal.
Turn the ignition to the ON position with the engine OFF.
After all warning chimes inside the vehicle have stopped, turn on the Tech 2.
On the TIS terminal go into SPS Programming.
Select Pass Thru programming.
Follow instruction on the TIS terminal. When you get to the Supported Controllers screen.
7.1. Scroll down in the top box and select BCM (Body Control Module).
7.2. In the lower box select Normal.
7.3. Select Next.
Important: Vehicles without the Driver Information Center (DIC) and power door locks/windows will have two calibrations from which to choose. A selection is requried before you can select NEXT. Select calibration 25814828. Do not select calibration 25788372.
Select NEXT when the calibrations screen displays.
Follow on-screen prompts until programming is completed.
When programming is complete.
10.1. Turn off Tech 2.
10.2. Turn the ignition switch to the OFF position.
Wait 30 seconds.
Turn the ignition switch to the ON position with engine OFF.
Turn on the Tech 2.
Go into diagnostics and check for DTC codes.
Clear all codes.
Important: Failure to successfully reprogram the BCM may result in the odometer displaying mileage in metric units instead of English units. To reset the odometer to display mileage in English units, remove the 10 amp fuse from the underhood BEC. Do not reinstall the fuse for 5 minutes.
Important: After reprogramming the body control module (BCM) the driver information center (DIC) will display tire pressure values as dashes. Do not perform the Tire Pressure Monitor Reset procedure. The Remote Control Door Lock Receiver (RCDLR) will update the instrument cluster with tire pressure values during the next driving event. The vehicle must reach a speed of 40 km/h (25 mph) in order for the RCDLR to update the display.
For vehicles repaired under this service update, use:
Add: Test & Charge Battery
Add: Test & Replace Battery
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer".

It takes a lot longer than 15 minutes for the vehicle's alternator to fully charge a discharged battery. This also places a lot of load on the alternator and is not good for it. Since there is no reserve current in the battery, all the current for the fuel injection, ignition, and electrical accessories has to be supplied by the alternator. This places a significant load on it.
