I just bought my 4th white burb. It had no key fobs, that was OK until I put on new tires and now I have a Service Tire Monitor warning. The easiest way to set up the TPMS is to use the key fob. The alternate way is to " park brake on, ignition on, cycle exterior light switch on to off, 4 times in 4 sec" It does not work. Should I get a fob? or is this a sign of other problems?

Any help is greatly appreciated

To reset the TPMS Identification Codes, please follow these instructions:

You will have one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer than one minute, 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 will need to start over.

The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the headlamp switch from off to the parking lamps setting four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light will begin to flash. The double horn chirp and flashing TPMS warning light indicate that the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The SERVICE TIRE MONITOR message will be displayed on the Driver Information Center (DIC).
4. Start with the driver’s 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 10 seconds, then stop and listen for a single horn chirp. The single horn chirp should sound within 15 seconds, confirming that the sensor identification code has been matched to this tire and wheel position. If you do not hear the confirming single horn chirp, you will need to start over with Step 1. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage or a key.
6. Proceed to the passenger’s side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger’s side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver’s side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left rear tire, check to see if the TPMS warning light is still flashing. If it is, turn the ignition switch to LOCK to exit the sensor matching process. If the TPMS warning light is not flashing, the five minute time limit has passed and you will need to start the process over beginning with Step 1.
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

The spare tire does not have a TPMS sensor. If you replace one of the road tires with the spare, the CHECK TIRE PRESSURE message will be displayed on the DIC screen. This message should go off once you re-install the road tire containing the TPMS sensor. The SERVICE TIRE MONITOR message is displayed when the TPMS is malfunctioning. One or more missing or inoperable TPMS sensors will cause the service tire monitor message to be displayed. See your dealer for service.

For your reference, this information is also available in your owner's manual in the Tire Pressure Monitor System section (starting on page 5-56). A digital copy of the manual is available at: http://www.extendedgmwarranty.com/ow...t-Suburban.pdf

It is also available at the GM Owner Center at: GM Owners Center - GM. The Owner Center allows you to access digital copies of your owner's manual, service records, schedule dealer appointments and many more features, all free to our loyal GM customers.

I hope this information was helpful.

If you have any additional questions, please feel free to contact me.

Have a great day!

I found the problem. I realized that the park brake light was not comeing on on the dash. Flipped the contact a couple of times, now the light comes on and the ECM enters teach mode correctly.

Thanks
