New rims and TPMS reset.......

I have a 2007 LTZ and I recently put 22" Escalade rims on the truck. For the first few days it looked like the TPMS was working but today all of a sudden I get the amber tire icon on the dash and a message to "service tire pressure system" and all 4 tires shows -- -- where the PSI should be.

These Caddy rims came off a 2008 or 2009 and they should have the sensors in them as it looks like the original tires. Is there a way to make the system learn the new sensors?
 
there is no real "auto-learn" feature.

when rotating the tires or changing the wheels you have to manually reset them:

let me point out, you want to release air for a 5 mississippi count then stop, and wait for the horn to sound, which can take up to 1 minute after you stop, if you continue to let air out past a count of 5 you will never get the horn to sound as it is waiting for the change in pressure to stop, before it reads the sensor.

from your owners manual:

You have two minutes to match the first tire/wheel
position, and five minutes overall to match all four tire/
wheel positions. If it takes longer than two minutes, to
match the first tire and wheel, or more than five minutes
to match all four tire and wheel positions the matching
process stops and you need to start over.

The TPMS sensor matching process is outlined below:

1. Set the parking brake.

2. Turn the ignition switch to ON/RUN with the
engine off.

3. Press the Remote Keyless Entry (RKE)
transmitter's lock and unlock buttons at the same
time for approximately five seconds. The horn
sounds twice to signal the receiver is in relearn
mode and TIRE LEARNING ACTIVE message
displays on the DIC screen.

4. Start with the driver side front tire.

5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire's air pressure for five seconds,
or until a horn chirp sounds. The horn chirp, which
may take up to 30 seconds to sound, confirms that
the sensor identification code has been matched to
this tire and wheel position.

6. Proceed to the passenger side front tire, and
repeat the procedure in Step 5.

7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.

8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5. The horn sounds two times to
indicate the sensor identification code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active. The
TIRE LEARNING ACTIVE message on the DIC
display screen goes off.

9. Turn the ignition switch to LOCK/OFF.

10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.

11. Put the valve caps back on the valve stems.
 
Thanks once again for your help. Geez I didn't even think of looking in the owners manual. I'll give it a shot.

Jesus that was almost too easy! It took me all of 1 minute to complete this procedure, worked perfectly! The Escalade sensors matched right up the the Avy TPS.

Thanks again for the help!!!!!!
 
I just had to replace a sensor (DRIVER REAR) and did this procedure. The new sensor still reads at --.

It honks twice at the PASSENGER REAR for some reason.

Any ideas? :E:



***Got it sorted***
 
I changed my rims over today and went to do the rest as described above. But I never got past the first tire.
However, the TPMS light has not lit up, and the truck is reading the rims and tires I put on. I found this strange. Wondering if anyone has had switched rims and tires and had not needed to get the truck to re-learn?
