Ok - MY 07 is about to get a new set of shoes....bought a set of GM's 22 inch stock wheels to replace my stock wheels. If they both have the tire pressure sensors, what else will I need to do?

I remember on my corvette, I had to use a large magnet to calibrate the tire pressure sensors to the car to retrieve the signals.....will I need to do anything like this here???

Thanks,

Steve

Steve the magnet does not work on these sensors. Depend on how old the wheels are there are two different sensors for 07', the early sensors were aluminum, a few months back they switched to rubber, they say you can switch them, well it did not work on my newest 07', I had to get the newer sensors for my winter 18" wheels (I have the stock 22's) In you owners manual there is a reset process, I will post it below. Note: this process did not work on my truck, I went to a Caddy dealer and they did it for me in 5 minutes with their Kent Moore scanner tool, I did not buy the truck from them, just a nice service manager.

Hello I am a certified cadillac tech I hope this helps




Tire Type/Pressure Selection
To provide a more accurate function of the Tire Pressure Monitoring System, it is necessary to update the Remote Control Door Lock Receiver (RCDLR) with the correct tire type and pressure information. Using the Tech 2, follow the steps listed below to select the appropriate tire type/pressure:

Install the scan tool.
Turn ignition ON with engine OFF.
Enter "Diagnostics" and build vehicle according to model year, vehicle line, etc.
Select "Body."
Select "RCDLR Module."
Select F2: Module Setup.
Select F5: Tire Type/Pressure Selection.
Select P-Metric Standard.
Select the front and rear tire pressure as noted on the new vehicle driver door placard sticker for the accessory wheels/tires.
Verify that the selections made are correct and press the enter key. The scan tool will flash "Procedure in Progress", then display "Procedure Complete."
Press the "exit" key to escape.
Tire Pressure Monitor (TPM) System
Important: Tire pressure sensors for 2007 model year full-size utilities are not compatible/interchangeable with pre-2007 model year full-size trucks and utilities and vice versa.

To avoid system malfunctions, it is necessary to install tire pressure sensors in the accessory wheels. Replacement sensors GM P/N 19155710 can be obtained or sensors from the OE wheels can be transferred to the accessory wheels. After the wheels are installed on the vehicle, it is necessary to learn the new sensor identification codes/locations into the remote control door lock receiver (RCDLR).

TPM Sensor Relearn Procedure
Turn ON the ignition, with the engine OFF.
Apply the parking brake.
Important: If the learn mode cannot be enabled, ensure the TPM system is enabled in the RCDLR. Use the following steps to enable the TPM system.

Install the Tech 2 to the vehicle.
Turn ON the ignition, with the engine OFF.
Enter "Diagnostics" and build vehicle according to model year, vehicle line, etc.
Select "Body."
Select "RCDLR Module."
Select "Module Setup."
Select "TPM Option Enable."
Press the exit key to escape.

Using the DIC, press the vehicle information button until the RELEARN TIRE POSITIONS message displays. If your vehicle does not have the DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the RELEARN TIRE POSITIONS message displays. If your vehicle has the DIC buttons, press the set/reset button. The horn will sound twice to indicate the TPMs receiver is ready, and the TIRE LEARNING ACTIVE message will display. If your vehicle does not have the DIC buttons, press and hold the trip odometer reset stem until the horn chirps twice and the TIRE LEARNING ACTIVE message is displayed.
Alternate method: Simultaneously press the keyless entry transmitters lock and unlock buttons until a horn chirp sounds or use the scan tool and select Special Functions/Sensor Learn Mode Enable/Enable soft key. A horn chirp will sound indication the mode has been enabled.

Starting with the left front tire, hold the antenna of the J-46079 against the tire sidewall close to the wheel rim at the valve stem location then press and release the activate button and wait for a horn chirp, or increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
Right front

Right rear

Left rear

After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
After the learn mode has been exited, adjust all tire pressures to the recommended PSI.
Spare Tire Hoist (22" Wheels Only)
Important: The new spare tire hoist is necessary due to the added amount of stress that the 22" wheel/tire system causes to the factory installed tire hoist. The tire hoist is also needed even if you do not put a 22" spare under the vehicle.

Replace the spare tire hoist with GM P/N 19158309. This modification is required for the following vehicles when installing 22' wheels.

2007 Cadillac Escalade

2007 Cadillac Escalade ESV

2007 Cadillac Escalade EXT

2007 GMC Yukon Denali

2007 GMC Yukon Denali XL

The following procedure should be followed for this modification.

If the vehicle is equipped with a spare tire stowage lock cylinder, open the spare tire lock cover on the bumper and using the ignition key, remove the lock.
Rotate the hoist shaft counterclockwise in order to lower the spare tire to the ground. Continue to rotate the shaft until the spare tire can be pulled out from under the vehicle and removed. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower.
If the secondary latch is engaged and the cable end is visible, perform the following procedure:
3.1. Tighten the cable by rotating the hoist shaft clockwise until you hear two clicks or feel it skip twice. You cannot overtighten the cable.

3.2. Loosen the cable by rotating the hoist shaft counterclockwise 3 or 4 turns.

3.3. If the spare tire can be lowered, repeat steps 1 and 2 to see if the spare tire can be removed.

3.4. If the spare tire cannot be lowered, rotate the hoist shaft counterclockwise until approximately 152 mm (6 in) of cable is exposed.

3.5. Raise and support the vehicle.

3.6. Place a transmission jack, or equivalent, under the spare tire.

3.7. Position the center of the transmission jack under the secondary latch release button at the center of the spare tire. Arrange the arms of the transmission jack so they will support the tire after it has been released.

3.8. Raise the jack until the spare tire stops moving upward and is firmly held in place, releasing the secondary latch.

3.9. Lower the tire. If the spare tire is hanging by the cable, rotate the hoist shaft counterclockwise until the tire is low enough to remove.

If the secondary latch is engaged and the cable end is NOT visible, perform the following procedure:
4.1. Raise and support the vehicle.

4.2. Place a transmission jack, or equivalent, under the spare tire.

4.3. Position the center of the transmission jack under the secondary latch release button at the center of the spare tire. Arrange the arms of the transmission jack so they will support the tire after it has been released.

4.4. Raise the jack until the spare tire stops moving upward and is firmly held in place, releasing the secondary latch.

4.5. Lower the tire and remove it from the jack.

Raise and support the vehicle if it is not already raised.
Depress the tabs, remove the guide shaft from the hoist collar, and slide the shaft toward the bumper.
Remove the collar from the hoist.
Remove the bolt.
Remove the hoist from the bracket.
Remove the spare tire hoist shaft guide from the bumper.
Install the spare tire hoist shaft guide to the bumper.
Install the hoist to the crossmember.
Install the bolt.
Tighten
Tighten the bolt to 40 Nm (30 lb ft).

Install the collar to the hoist.
Install the shaft to the hoist.
Install the spare tire to the hoist.
Rotate the hoist shaft clockwise until the spare tire is in position and the hoist clicks two times or it skips twice. You cannot overtighten the cable.
Remove the safety stands.
Lower the vehicle.
Install the spare tire stowage lock cylinder.
Module Reprogramming

Thank you for the post. It is appreciated. I transplanted my sensors on my 18" oem to my new 24" custom rims. I tried the relearn process; however, they are no longer detected? Any ideas why this is so? After I put in in "learn mode" I went to the front left tire and let air out for at least 10 seconds. Still no chirp. I practically continued to let air out until the entire tire was deflated and still no chirp? Do you think if I bring it to the dealership they can make it recognize my tire using an alternative method (intead of deflated or inflating the tire)?

Many owners including myself could not get the programming to work via letting air out, or inflating the tires. I have two 07's and put 18's on for my winter tires and put 22's back on in the spring, one of my two 07's worked one time with the pressure release method, the other "newer" 07' did not, after a trip to my local (not my selling dealer) dealer they used their Tech II Tool and did not charge me, I gave the guy $20.00 and he seemed happy. I purchased my own tire programming tool, it is a Bartec and works on every sensor made, for me it was worth it, got in new on E-Bay for half price and it's very easy to use. :) Any owners in the Phila area I will gladly program your sensors at of course no charge. :)

Using the Tech II Tool or another brand programming tool will work, read my post above. :)

I have perfectly functional sensors with 22s and toyo proxies.

As I have always done for best performance and mileage I cranked the pressure up to the 50psi max and all of a sudden my tpms sensors are not registering properly in the DiC.

It looks like all that needs to be done is the process outlined by EROD316 above. However I contacted my mdealer to do this and they were very reluctant to even discuss this and claim that they are legally bound to maintain the pressures listed on the vehicle.

Are there any forum members that have successfully worked with their dealer to adjust the tpms monitor and computer?

Are there any suggestions on how to ask for this without them referencing the firestone/ford explorer issues?

Thanks!

Wow that's a lot of posts on sensors ...

Step 1. Drive to any GM dealership
Step 2. Ask service manager nicely if he can have a tech flash your TPMS for you
Step 3. Drive away

99% of dealerships will do it on the spot as a courtesy, especially Cadillac dealerships ... if they don't you know where not to buy your next vehicle from and just go to another dealership.

I had 1 sensor relearned, and the dealership charged my $57 :-|

Damn man, that's insane.

If the dealer won't do it for free out of courtesy then just drive by the bays of any large tire store, hand a tech a twenty and they'll do it.

I guess I must be lucky, every dealer I've ever gone to has done it for me on the spot for free.
