So i was a day late hooking up the battery tender this weekend, thanks in part to the trunk lid not closing all the way and the light staying on all night.

now neither keyfob works at all. battery is back to fully charged.

came across the TSB below. Do i seriously have to go to the dealer for this? all i want in life is to never have to go to a dealer.
I have also seen inconclusive threads here about "yes you can/no you can't reprogram the fobs yourself".

Mine is a 2008 and the manual has no such programming instructions.

Yes it is my fault for draining the battery, but can;t the system be designed such that the car doesn't lose basic functions as a result of a relatively common event?

Sorry, I am not excited about the prospect of paying $100 and sitting at a dealer for a couple of hours.

Subject: Key Fobs Inoperative, TPM System Not Reading Correctly - Dashes On All Four Tire Readings, DTCs C0775, C0569, B3105 Set, Unable to Program TPM Sensors (Reprogram RCDLR)


Models: 2008 Chevrolet Cobalt, HHR, Malibu

--------------------------------------------------------------------------------

This bulletin is being revised to update the Important statement to reflect the new direction to no longer contact TCSC. Please discard Corporate Bulletin Number 08-03-16-001A (Section 03 - Suspension).


--------------------------------------------------------------------------------
Condition
Some customers may comment that the key fobs are inoperative or that the TPM system is showing dashes as the reading for all four tires.

Technicians may find DTCs C0775, C0569 and B3105 set simultaneously in the RCDLR module.

In addition, the technicians may find Tire Pressure Monitoring sensors are unable to be programmed to the vehicle by adding or releasing pressure to the tire while the vehicles in the TPM learn mode.

Cause
These conditions may be caused by the following:

• The RCDLR may lose its transmitter and tire pressure monitoring data from its memory if a low voltage condition occurs on the vehicle.

• The ability for TPM learning by adding or releasing pressure to the tire has been disabled in the RCDLR.

Correction
Reprogram the RCDLR with an updated software calibration to address both issues listed above. This new service calibration is available on TIS2WEB using Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software.

Important: If the Tech 2® could not establish communication with the RCDLR AND the programming event ended with error, attempt to reprogram in Service Programming System (SPS) by selecting "Remote Control Door Lock Receiver (TSB 08-03-16-001) with E4399 error -- Pass Thru Only".

Once the RCDLR module has been reflashed with the latest software and calibrations, the following may also be necessary:

• Relearn all keyless entry transmitters.

• Reconfigure the tire pressure placards and the tire type.

• Relearn the tire pressure sensors.

Refer to SI for the procedures to relearn transmitters, placard and tire type configuration and tire pressure sensor learn.

If you need to get that fixed, the only way to do it is at the dealer.

Jeff,

The car is actually designed to retain the setup data, but a programming error turned that ability off. Part of the procedure is to correct that error.

Unfortunately the only way to get the car to learn an RKE transmitter (aka fob) is with a Tech 2.

The more ominous problem to me is how this started. The trunk light shouldn't, as far as I know, be able to stay on all night. The Inadvertant Load Control relay should turn it off after 20 minutes. I will check mine tonight to be sure, but I am fairly certain that is the way it works.

It seems I have to make this trek to the dealer too. When I picked up my car in '09 (it was a showroom queen) the battery was dead and though they had charged it, the fobs didn't work. They 'fixed' it and I thought they'd done the TSB reprogramming then, but a couple of days ago I rotated the tires and attempted to do the TPMS relearn using the manual's pressure drop/raise method. Nothing. Sigh. I guess the TSB DIDN'T get applied. B*stards.

(The selling dealership was one that was dropped by GM. I wonder why.)

Can the tech 2 relearn the rke without doing this update?

Ie you get your key fins back but you remain at risk with the next battery dead event?

And why does this happen when it goes dead but not when I purposely disconnect the battery?

Yes. There are two separate procedures. One is to program the car to read the RKE transmitter. The other is to update the software so that loss of power will not erase the programming.

Yes. If the software update is not done, you are still at risk.

Speculation ? Maybe you haven't had the battery disconnected long enough to cause the memory loss. Control modules frequently have an internal capacitor that will store enough charge to ride it through a "short" power loss.

The battery was dead for hours. The car went without a battery for days maybe weeks when it was having work done. I suspect something happened as the battery died that jolted the receiver memory somehow. I guess I should worry that it might be in worse shape than just suffering from memory loss.

Thanks for the quick replies.

Very possible. Did you jump start the car, or just charge the battery until it was able to do it ? Jump starting has been known to cause odd issues.

I am still bothered by the trunk light running the battery down.

Thanks JR for pointing this out...

Ahem. From another thread...

For the first time in the history of solstice forum, soup isn't entirely correct.

Yes the power remains on, but only for the 10-15 minutes that the car keeps accessory power on. Then it goes into battery save mode and shuts it off.
Ohhhh, BAZINGA! :devil: :devil:

Oh don't start soup!! I was wrong way before and many times. My comment was about the mirror. So there.

You and your pristine image had been infallible until that one little slip up and the only reason I said it was because I had to disagree with you but I wanted it known that it was with all due respect to a valued contributor and a known source if excellent info.

So take the compliment, leave me alone and go work on your next awesome jealousy inspiring project that most if us couldn't even imagine let alone execute! :)

As for the trunk light, I have no evidence it was in but I find it odd that the battery died overnight and the only thing was that the trunk didn't latch all the way.

I didn't jump the car. I never tried to start it before this or since it charged back up. Just all of a sudden no juice.

Children, children, children. Don't make me stop this car to separate you .....

Does your battery tender monitor the battery, and give you a warning if there is a problem ? If so, has it ever indicated any battery issues ?

Was the battery completely dead ? Or just too weak to start the car ? What were the symptoms ?

Do you always use a tender ? How long has the car sat recently without one plugged into it ? How old is the battery ?

Depending on the background, I would be inclined to leave the car overnight without the tender (being sure that the trunk light is off) and see what happens.

Judy's Saab has an intermittent problem that will kill the battery overnight. It is very random, and so far the best I can surmise is that the cooling fan is coming on when it shouldn't. We put it on a tender whenever she parks it, and sometimes the indicator light will be blinking, indicating what the charger thinks is a bad battery, but is most likely the phantom discharge.

I miss the days when turning off the key actually turned off the car.

Amen to that. I just don't understand pulling into my garage in daylight, turning off the car and having the headlights turn on . . . (A different GM automobile than the Solstice).

:dunno:

That's exit lighting, usually programmable to turn off depending in the car. It's to light up a dark area so you can see your mugger as you got out.

Speaking as someone who has seen this problem several times with cars I have rebuilt, the solution is the dealer. Take a printed copy of the above bulletin and it should be a NO Charge procedure with a little insistence. This problem only exist on 08 models. With the reprogram of the updated software to the RCDLR it will hold the programing no matter how long the battery is dead. JR is correct in that the RCDLR will stay active for a short period with the existing programing. One other ponit to add, if you have different tires and want to use a different pressure setting before the TPMS report low pressure you can have them reset that to your preference. Also make sure you take all remotes when you have this done as it will disable any that do not get the new programing. Hope all this helps the procedure usually takes about 35 min.

This is the first time the car has been hooked up to the tender. like i say, a day late.

it was completely dead. the car wouldn't do anything or even acknowledge the door was opened.

the car had been through a lot of me tinkering without starting it, but it never showed any issues until the next morning. it opened the trunk once and that was it.

that all the detail i have on it.

If a key FOB no longer works properly, having it looked at by the dealership is recommended. Every FOB has a signal to match the vehicle and must be programmed by GM Techs. Please keep us posted and send a PM if you have any issues regarding repairs. If you send a PM, please include the VIN#, your contact information, and situation. I hope this is resolved quickly.

Matt,

While pursuing an engine warranty repair, I was able to add in this TSB to resolve exactly the same set of problems: low-battery condition caused crazy computer reboots, unpredictable behavior, and then (after changing the battery), the TPMS and key fobs eventually--not suddenly--stopped working. The module was so confused that it didn't even register TPMS as an option in the GM DIC choices despite the fuse showing a completed circuit from power distribution.

This sort of module "wake up" requires at least a Tech2 device to survey, though the dealer I went to mentioned having used a direct serial connection after initial problems getting the module to work. Though they never referred to it as such, all these features and more are handled by the OnStar box. The flash update was also applied.

As for "free", I agree it should be since this is a corrective measure against a programming flaw and I'm out just under $100 for the diagnostics/flash work that the dealer performed. Since it's not the sort of thing GM will reimburse them for, I'm okay having paid and knowing that my car's better protected from such problems in the future. I think in the end they mildly undercharged me for such a shop service, perhaps because I was able to tie it so solidly to the TSB.

Thanks, all.

-Jeff
