i just replaced the battery in my 2008 hhr but now my key fob wont work. i replaced the fob battery, still no luck. my guess is that it needs to be reset somehow. any suggestions?

Your car may have lost the key fobs from memory. Sense you have an 08 your car would apply to this tsb. I had to have this done on my car when it was under warranty.

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.

Perfect Lucky, I knew there was a TSB that might apply to tgg1304's issue, but it was hiding from me.

Great work as always Mr. Technical Moderator.

Since replacing my battery the TPMS is displaying dashes. I found this info here and have already tried this but no changes,. any suggestions. Also, my key fob hasnt worked since battery change as well.



"Q: Why are dashes (" - - "), or a pressure value of 148 PSI (1020 kPa), sometimes displayed after a battery disconnect?
A: These displays come up after a battery disconnect/reconnect because the system is waiting for updated pressure information to be sent from the tire pressure sensors. As each sensor transmits its information, the display is updated appropriately. Note that when dashes or 148 PSI (1020 kPa) are displayed after a battery disconnect/reconnect, the System Malfunction warning is NOT displayed - because the system is still working properly, and simply waiting for updated information from the sensors. Driving the vehicle above 20 mph (32 km/h) for 2 minutes gets the sensors talking, and restores the correct pressure values to the display. It is also possible to restore the values by using the J-46079 TPM tool, using the "Activate" function at each tire to activate the sensor (it is NOT necessary to put the system into Learn mode, in this special case)."

So the tsb that I posted in your other thread didn't fix your problem?

Help me here Lucky, the OP's HHR is an '08 if I recall, and did we or did we not suggest the possibility of dead or dying batteries in the TPMS Sensors?

And we did suggest a "Lobotomy" also as a possible solution due to its resetting the vehicle to a "baseline" condition?

Captain, perhaps a Vulcan thread meld!! Would avoid confusion!

Threads Merged, the Planet Vulcan is now safe.

Lucky

I'm not sure what's happening?

Live long and prosper! Sensor readings indicate the Scan tool II is required to relearn the TPMS
