TPMS issues - finally a response!

[Nine Ball]

Terri, the only sensors I'd say work are the ones that came on your car. At least, they DID work. Who knows now. TPMS system in this car is crap.

You cared sooooo much about my issue that you didn't drive my car to assess the problem when I showed up for you to do so. I let it go because you eluded to the fact you had to get back home and it was too busy. You end up spending the night in N.O. You could have driven it outside the show. You were leaving anyway.

I've had to go thru Savini, even though it's not what they do. They deal with a retailer, NOT an end customer. So I've had to go through extra channels and time. They have been gracious enough to help me. NO THANKS TO YOU.

Considering my wheels vibrate, have been back once and now twice, my sensors don't work, and my car is on jackstands, .......... Ya, I think to answer a question without a smart ass response shouldn't be too much to ask.

I can understand PQ's frustration as I would be upset as well if the wheels I paid a lot of money for were having issues. However this is a manufacturer issue not a vendor. I was there when you chatted in person and it wasn't just having to get to the next destination it was the fact that the parking lot was packed. If I recall you were working or going to work. When we split it probably took us another hour or more to get out of the parking lot.

He did give you avenues to pursue to resolve the issue (tire defects?) Have you verified that's not the issue? They came back from Savini with them saying they're "in tolerance" correct?

I dont think he was ignoring posts in here it's just an "unknown problem" at this time. Who knows when the cutoff was on the sensors, who knows why they're not all having the issue. At least this could be a step in the right direction towards figuring it out and resolving the TPMS wacko readings people are getting (myself included!)

Hell I'm pretty sure my body guy's camaro doesn't have an issue with the TPMS on his car with wheels and it was the first in Houston. Regardless of the VIN "cutoff" it seems cars from all over the spectrum are having problems but the MAJORITY of the ones that are "ok" are early early early models.

Have you had the wheels and tire balance checked on a road force machine?

OK,I'm going to check the parts catalog out for notes and different part numbers when I get to work in the morning.
I'm also going to check for TSB's on this.

Did this make any difference?
I have the GM TPMS purchased in February and never had a problem. Since I don't have the electronic tool to set the sensors perhaps that is the key to the problem.

Maybe that .1 mhz is picked up by the Camaro and the electronic tool reads it .1 mhz off, so eventually the signal drifts and loses connection after you go on the highway.

This may also explain why the vin cut off doesn't make sense, and both newer and older cars have the problem.

Only other thing I can think of, which is crazy, but does it have something to do with the non OEM wheels?

[MS3DALE]

They want you to reprogram the BCM....

Service Information




Document ID: 2365988
#PIC5174G: Difficulty With Tire Pressure Indicator Sensor Learn Process - accessories accessory BCM GM inch monitor program RCDLR receiver suspension TPM wheel - (Nov 2, 2009)

Subject:Difficulty With Tire Pressure Indicator Sensor Learn Process

Models:2010 Buick LaCrosse
2010 Chevrolet Camaro
2010 Chevrolet Equinox

This PI was superseded to correct VIN breaks. Please discard PIC5174F.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
<A href="http://gsi.xw.gm.com/si/showDoc.do?docSyskey=2365988&releaseDate=2009-11-02&name=Difficulty+With+Tire+Pressure+Indicator+Se nsor+Learn+Process+-+accessories+accessory+BCM+GM+inch+monitor+program +RCDLR+receiver+suspension+TPM+wheel&from=ns&bulle ti#ss1-2365988">Condition/Concern:

When performing a tire pressure indicator system learn after a tire rotation or service (including Camaro after installing SPO 21 inch accessory wheels), you may encounter an issue during the relearning process, after relearning 1 to 3 of the 4 tire pressure monitor sensors, the system will time out and not complete. This is due to a BCM software issue that allows the system to pick other vehicle signals in the area and fill up the BCM storage buffers.
Note: If the learn process does not properly complete the system will set a TPMS light and DTC.
<A href="http://gsi.xw.gm.com/si/showDoc.do?docSyskey=2365988&releaseDate=2009-11-02&name=Difficulty+With+Tire+Pressure+Indicator+Se nsor+Learn+Process+-+accessories+accessory+BCM+GM+inch+monitor+program +RCDLR+receiver+suspension+TPM+wheel&from=ns&bulle ti#ss2-2365988">Recommendation/Instructions:

DO NOT replace a TPMS or BCM for this issue.
If your vehicle was built before the below breakpoints, there is a new BCM calibration to correct this condition.
Vehicle
VIN Breakpoint (last 8 digits)
2010 Buick LaCrosse
AF113760
2010 Chevy Camaro
A9132183
2010 Chevy Equinox
A6209664
If built before please follow the below pathing for programming.
Reprogram the Body Control Module (BCM) using TIS2WEB, with the latest calibration. In the TIS2WEB screen, be sure the calibration within the BCM selections for the Chassis Control or I/P Occupant Display lists the calibration that states "New software set to resolve TPMS manual learn".
Important: After reprogramming BCM the following must also be completed or vehicle will return:
Note: After programming the BCM It will be necessary to perform the (BPP) Brake Pedal Position sensor calibration. If the BPP sensor calibration is not performed, a DTC C0277 will be set and the cruise control will be inoperative. This may also cause a concern with the brake lights not coming on with a light brake apply. If the BPP sensor is not calibrated, it may take more brake pedal travel to turn the brake lights on.
There are two different methods to perform the BPP sensor calibration.
Method 1 using the MDI tool and Service Programming System (SPS) on the TIS terminal.

1. <LI type=1>Connect the MDI tool to the vehicle and access Service Programming System (SPS) on the TIS terminal. <LI type=1>Build the vehicle on the Service Programming System.
2. Select BCM Setup, and follow the instruction on the SPS terminal.

Method 2, using the MDI and GDS software.

1. <LI type=1>Connect the MDI tool to the vehicle. <LI type=1>Use the GDS software, and connect to the MDI. <LI type=1>Build the vehicle on the GDS software. <LI type=1>Select Module Diagnosis. <LI type=1>Select Body Control Module. <LI type=1>Select Configuration/Reset Functions.
2. Select Brake Pedal Position Sensor Learn.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

That part number doesn't even come up as being any good in the catalog,HOWEVER....whenever I call GM they tell me that part#12768826 can be used in place of part#20922900,which is the only part number they list for the 2010-2011 Camaro's...20922900,and they list it as being 315 MHZ.

Randy, I asked you to show up on Friday at the event. I understand you couldn't take off work, but I also suggested Friday evening after the show. Instead, you decide to show up Saturday morning, when everyone was packed and ready to head home after a long week. The traffic was horrendous, that is the only reason you saw us in the first place. We attempted to leave almost an hour earlier, and our cars didn't budge. I had all day Friday to help you, but you never contacted me. Remember, we were the ones that walked up to you Saturday. You never attempted to contact me, had we not seen you it would have never happened.

As for yourself and Savini, I absolutely have done everything I could with your case. Savini asked to handle it directly, as they want to make sure you end up happy. How dare you say I've not spent any time on your case! I've spoken with the sales manager numerous times, trying to get something worked out. Even got them to agree to get you another set of 20s at pure manufacturing cost. I've made suggestions about your tires, but you haven't acted on it. I have well over 100 emails/PMs from you, which I always responded and gave advice. Probably another 100 replies to your wheel threads too. All this time spent, and I've earned $0 on your deal with Savini. Jeff at Savini asked me to help locate some active/key members here, that they would hook up at cost. That was you. You saved about $1,500 off the normal pricing. This was a promotional deal and you accepted it. It wasn't a typical retailer deal. I don't know about you, but as a customer with issues, I'd be elated to deal directly with the guys who can fix or replace my product. What more can I do? Realistically? You have a direct line with the pros, no thanks to me? I set that line of communication up!

I understand you are frustrated. I'm also frustrated by your wheel issue, especially since it isn't resolved. No need to take it out on me. I don't have the answers, it seems nobody does.

MS3DALE:
My car's VIN is after the one you listed in the service bulletin.

My car was built on January 11, 2010 and the VIN is 181297.

I bought sensors from the dealer last week and they ordered them based on my VIN. The sensors they sold me are: sensor part number 12768826 with FCC number on the sensors is MRXG43MA4S.


I am having the problem with the learn process with the after-market sensors Nine Ball gave me with my wheels. I am going to take those out of my wheels this week. My question is this: Should I put the sensors the dealer just sold me (listed above) in my new wheels to fix the problem, or do you recommend I take the sensors out of my stock wheels (I still have them)?


Apparently my car was built after the cut off date for the service bulletin you listed. So, I don't think updating the car's system as stated applies in my case. Thanks.

[Nine Ball]

Terri,

Since there appears to be only one sensor part number, it is likely still a BCM (Body Control Module) or TPMS system software issue. Keep in mind that even though the sensors themselves have the same part number, they each still have their own identity coding. This coding is what the TPMS system stores, so that it knows which sensor is which. I'd hate to see you spend more money to change out sensors and end up with the same issue again. We may be needing another BCM fix, but I have no idea if that is in the works. Seems the relearn procedure is the problem here, not the actual sensors.

How about this, I have two local cars with the issue now. Let us do the swaps back to the OEM sensors in one (or both) of them first. If it is successful, then you will have your answer. And, it won't cost you anything to wait. Its the best idea I can come up with for now. This probably won't happen until this weekend though, as all three of us are doing offshore related work this week. Will is currently owned by BP, Adub too.

FYI.. I've got an extra set of late model tires and wheels laying around if you need...

[Darth_Emma]

Tony:
I'll wait and see what happens at your end and then I'll know better what to do.

I mostly want to know if I should return the TPMS I bought last week from the GM dealer. I'll just hold on to those as well as my stock wheels for now until I know how things go for you.

Thanks for helping us figure this out.

This really shouldn't be so complicated!
