Need to replace a sensor on my 2001 Euro spec C5, I have managed to change the battery in one but a second has now given up the ghost and a new battery has not worked this time.
Although a 2001 it is running the early sensors and of course they have to be euro spec for the correct frequency. The GM part number shows as GM 10438854.
Can anyone advise on where to get these as a search of the usual suppliers has only resulted in the US versions, just cant find a euro spec sensor.
Are there any other part numbers used for the euro spec version?
Any and all help appreciated
Mike.

 

FWIW

My parts manual shows PN 10316125 for both 2000 & 2001 export.

 

Thanks Sam, but I think that refers to the later syle sensors. the ones in mine are early type with manufacture date of 12/99.

 

My manual shows PN 10316125 for 1997 - 2002 (last year my manual goes to) for the export. Who knows, the export models may differ by area.

Maybe DeeGee whill chime in.

Below is a link were he posted about the numbers

http://www.pistonheads.com/gassing/t...PMS+sensor+%3F

 

The only reason I was questioning the number was when I did a search using 10316125 all the results seemed to be talking about later cars and even C6 with that number, its just so confusing with these euro sensors, I was considering going for the conversion kit to later sensors with the RFA but no one can tell me if that will work with Euro spec cars, will the RFA still talk to the rest of the electronics or is it just the sensors talk to the RFA on different frequency?

 

I searched but didn't find anyone who's done the Euro-domestic conversion and actually reported back. In short, my guess is that it would work but you won't know until you try. Here's some more detail that I hope helps.

Euro versus domestic RFA modules receive TPMS/keyfob transmissions over two different radio frequency bands (and maybe a third for Japan). Domestic pre-01 RFA and 01+ RFA use the exact same frequency (315 Mhz), but have different wireless packet content. This makes the TPMS/keyfobs non-interoperable with the different RFAs. But the RFAs pass the same OBD2 content so they are forward & backward compatible with the car.

All the C5 computers reported in the DIC diagnostics (RFA included) speak over the one-wire OBD2 bus and send messages to each other. I don't think the Euro PCM or BCM would differ in their OBD2 message content, as those are the recipients of the TPMS OBD2 messages.

If I were a betting man, I would guess the 01+ domestic RFA and TPMS would work with the Euro spec PCM/BCM. The newer "1" and "2" keyfobs I give a slightly lesser chance, but still likely.

Hopefully the FCC equivalent in England won't catch you broadcasting on an unauthorized frequency.

Thanks Todd, gives me some food for thought. I am interested in your comments ref new key fobs possibly being an issue, I think they could well be as my car also runs an after market alarm system with different fobs from GM although I still get the same functions, door lock, fuel cap, trunk etc, I could really do with someone who has actually done this conversion on a Euro car as $400 or whatever is a lot if the system does not work.
Does anyone have an idea where I can obtain the correct sensors assuming the part number suggested is correct 1031625, I have searched bur cant find any suppliers of these Euro version sensors.

 

The new alarm included different GM fobs? You should probably provide the model number of that aftermarket system, and the GM P/N for the fobs you're using. Is it in addition to the normal RFA, connects inline before the RFA (RFA talks "through" alarm), or replaces your RFA entirely? Do you perform any special fob training for the security system, or the normal DIC method for both the car & alarm?

My comment about the fobs not working was based on my attempts to get an '00 keyfob trained to my '02 car. It didn't work, but the '00 TPMS did. The 01+ keyfobs are coded for two drivers, #1 and #2 which can control unique seat and mirror positions. The pre-01s did not have that functionality, so I'm not real surprised the newer BCM didn't know how to interpret the older RFA's OBD messaging for keyfobs.

That would be ideal, but I don't think anyone has stepped forward yet. You may try p/ming other folks who asked about it in the past to see if they had tried. The additional layer of complexity also tying your alarm system in would lead me to suggest sticking with your current RFA. Likely no one will have an equivalent configuration, so you would be blazing a new trail.

That being said, the $395 upgrade package could easily be resold here if it didn't work. You'd just be out shipping both ways.


On the German Corvetteforum.de a user posted these compatible P/Ns for Euro-spec TPMS. Take it with a grain of salt. Hopefully it will help you with your search:

The domestic TPM's are made by Schrader, and you may be able to cross-reference the actual manufacturer's P/N to other equivalents as well.

 

The alarm I believe is simply wired into the main system under the dash I dont think it has a sepearate or different RFA, but I think it is too risky to try the conversion, plus by the time I have paid import costs and shipping I am in around $550 so if it doesnt work shipping back to sell is not really an option. Anyway back to my original question does anyone have or know where I can find Euro spec sensors, I have searched all the main sites googled etc but no sensors listed other than the US versions, I believe Corvette Don has been involved with the sensors replacing batteries etc , I have PMd him but no response as yet.
Any other ideas?
Mike.

 

Have you tried Bauer Millett? They sometimes have obsolete stock. The only other supplier I can think of is Keith at Eurovettes.

Forum member Bakersfield also used to refurbish batteries.

Not sure if this helps but I tried to put this together to answer a similar question. It's not definitive but the best info I could find.

The Remote Keyless Entry System

The remote keyless entry system shares components with the tire pressure monitoring system. Living in the UK there’s some confusion over which parts to use for which cars. I dug into the manuals to try to find the full story.
The main components are 2 key fob transmitters, 4 tire pressure sensors and a remote control door lock receiver (RCDLR) which acts as a common radio receiver for both elements.
Looking at the keyless entry system first, each key fob transmitter has a unique vehicle access code that changes every 5 seconds. As a security feature, the transmitter does not send the same signal twice to the RCDLR and the receiver will not respond to a signal that has been sent previously. This prevents anyone from recording and playing back the signal from the transmitter. Because of this feature, if a transmitter or receiver is replaced, each transmitter must be reprogrammed to the vehicle's receiver.
The Tire Pressure Monitor (TPM) system displays the tire pressures on the Driver Information Center (DIC). The system uses the Remote Control Door Lock Receiver (RCDLR), Body Control Module (BCM), Powertrain Control Module (PCM), 4 radio frequency transmitting pressure sensors inside each wheel/tire assembly, and a class 2 serial data circuit to perform the system functions. When the vehicle is stationary for more than 20 minutes the sensors go into power down mode. In this mode the sensors transmit tire pressure data once every 60 minutes, this minimizes sensor battery consumption. These batteries are not easily changed so have to be replaced once the batteries die. Typically, the DIC will read XXX to show a dead battery. As vehicle speed increases to 32 km/h (20 mph) the sensor's internal roll switches turn the sensors on and they will each begin to transmit a unique identification code and a radio frequency signal. The RCDLR receives and translates this data in to tire location and tire pressure. The RCDLR sends this data to the DIC via a class 2 serial data circuit where the tire pressures are displayed. For this reason the TPMs have to be programmed using a learning mode in the DIC to tell the car where they are mounted and to pass sensor data to the computers.
The US models have 2 different versions of TPMs with the older version being more expensive. There is a 3rd type for Euro models which, unfortunately, are also more expensive. Check with your vendor but the part numbers appear to be:
97-00 – 10438853
Apparently an after market Schrader TPS sensor part number 28006 will work with a 97-00 and is much cheaper
01-04 - 25773946
Euro – 10354987 (Tire pressure sensor export) There may be a new part number to replace this standard.
The key fobs are in 4 groups. It’s not clear why the 00 has a different part number but I believe it’s because the passive entry feature was deleted during the 00 model year:
97-99 - 10253839
00 - 10432147
01-04 - Number 1 Fob - 25695954
01-04 - Number 2 Fob – 25695955
Euro transmitters 97-04 (transmitter R/CON DR LK) - 10407640
The RDLCR part numbers for the US models are:
97-00 - Remote control door lock receiver - 10422621
01-04 - Remote Control Door Lock Receiver - 10312535
There is much confusion about frequencies. One Corvette Forum member (seoulbrooks) checked with Schrader who manufacture the OEM tire pressure sensor transmitters and elicited some good information. Both the US systems actually transmit at the same frequency of 315Mhz. Even though they operate on the same frequencies the receivers and transmitters have a year group specific code which must match for the transmitter and receiver to communicate. The older fobs and TPSs will not work with the newer RDLCR. The Euro transmitters work at a different frequency of 433 MHz for European emission compliance. I’ve been unable to verify that.
The part numbers for Euro versions:
97-00 - Remote control door lock receiver (Export) - 10426004
01-04 Remote Control Door Lock Receiver 10431034
It is possible to retrofit the later US standard into US 97-00 and Euro Vettes. The kit includes both fobs, a RCDLR, an RCDLR connector, 4 TPMs and mounting nuts. The kit is available from www.gmpartshouse.com for about $400 which is about the same price as 4 older sensors which are becoming harder to order.
You can program the TPMs using as strong magnet:
1. Turn the ignition to ON.
2. Press the RESET button in order to clear any IPC display warning messages.
3. Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
4. Press and hold the RESET button for 3 seconds.
5. Press the OPTIONS button again until the TIRE TRAINING message appears.
6. Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin the programming sequence.
7. Place the magnet over the TPM sensor.
8. The horn will sound, indicating the left front TPM sensor is programmed. (if not use a bigger magnet)
9. When the horn sounds, proceed to program the next TPM sensor in the order directed
by the IPC messages:
- LEARN R FRONT TIRE
- LEARN R REAR TIRE
- LEARN L REAR TIRE

Programming Cancellation

The programming mode will be cancelled if any of the following conditions are met:
• The program mode is exited through the DIC.
• The ignition is turned to OFF.
• All four sensors have been programmed.
• The TPM system has been in the program mode for longer than 2 minutes and no sensors have been learned.
If the program mode is cancelled with less than four codes stored, the receiver will only accept the codes programmed up to that point.
Fob Training
1. Turn the ignition to ON.
2. Turn the radio to OFF.
3. Press the RESET button on the driver information center (DIC) in order to clear any IPC warning messages.
4. Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
5. Press and hold the RESET button for 3 seconds.
6. Press the OPTIONS button until FOB TRAINING message is displayed.
7. Press the RESET button in order to begin the programming sequence. The message HOLD LK + UNLK 1ST FOB will be displayed.
8. Simultaneously press and hold the LOCK and UNLOCK buttons on the first transmitter for 15 seconds. The IPC will indicate when that transmitter is programmed and when to proceed to the next. Repeat this procedure for each additional transmitter or press the OPTIONS button to exit.
The receiver will cancel the programming sequence if any of the following conditions occur:
• The program mode is exited through the DIC.
• The ignition is turned to OFF.
• The three transmitters have been programmed.
• The RFA system has been in the program mode for longer than 2 minutes and no transmitters have been learned.
If the program mode is cancelled with less than 3 codes stored, the receiver will only accept the codes just stored. If the program mode is cancelled before any code is stored, the codes still remain valid.
The receiver retains all current access codes in memory if either of the following conditions occur:
• A programming sequence is interrupted.
• The battery is disconnected.
Synchronizing Transmitters
Perform the following procedure if a transmitter cannot communicate or becomes out of synchronization with the receiver:
1. Move a programmed transmitter within range.
2. Press the LOCK and UNLOCK buttons on the transmitter simultaneously for 7 seconds.
3. The horn will chirp once when the transmitter is synchronized. Repeat this procedure for each additional transmitter if needed.

 

Googling 10354987 brought up some dealers offering the part. I can't guarantee it will work as I have a US domestic C5 so my sensors are different. The descriptions seem to fit and are for a euro application. Maybe you could e mail to check?

http://parts.nalleygmc.com/products/.../10354987.html

http://www.gmpartsgiant.com/parts/gm...-10354987.html

You could also check the Forum parts vendors with that part number.

 

Thanks Dee Gee, I have emailed both of the adresses given with more detail as I am still concerned about getting the correct sensor, none of the numbers ever seem to match up. As I said at the start of this thread my sensor part number is GM 10438854 and as yet I have not seen that listed antwhere or any cross reference to it.
Will keep you informed
Cheers
Mike.

 

Getting there slowly, both of the sites listed have replied, one has no idea of the correct sensor plus cant ship to the UK, the other came back with an uncetain confirmation of part number but when pushed decided to come up with a totally different number, not installing confidence
However took your suggestion and contacted a few of the web site vendors and GM parts warehouse seem to be on the ball and offering a good price, just awaiting definate confirmation of numbers.
Thanks to all for their advice so far
Mike.

 

Good news

 

GM superseded 10354987 to new part number 20807214 which I have a couple dozen in stock if you need any.
