Installing Tire Pressure Monitoring in Older Wheels

I wanted to install the Hella TC-400 tire pressure monitoring system on a set of '80s vintage Alpina wheels to be used on my '72 2002tii. Older wheels are not necessarily suited for mounting the valve stems that incorporate tire pressure senders. The people at TireRack were very helpful and sent me a dead sender that I could use for a trial fitting. I mounted the valve/sender in the wheel and sent them photos showing the mounting angle etc. It all works fine! Please make sure your tire mounting person knows what they are doing and warn them that you have the senders mounted. See http://www.tirerack.com/accessories/detail.jsp?ID=51
Now I have a modern tire pressure system on a 38-year-old car!

Low tire pressure light stays on even though theres enough air in tires


That should be in your manual it should tell you how to reset it

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

service tire monitor on what is the problem? how do you reset the system?


TIRE PRESSURE MONITOR SYSTEM
The Tire Pressure Monitor System (TPMS) uses radio and sensor technology to check tire pressure levels. If your vehicle has this feature, sensors are mounted on each tire and wheel assembly, except the spare tire. The TPMS sensors monitor the air pressure in your vehicle's tires and transmit tire pressure readings to a receiver located in the vehicle.

The TPMS is designed to alert the driver, if a low tire pressure condition exists. This system also allows the driver to check tire pressure levels using the Driver Information Center (DIC).

When a low tire pressure condition is detected, the TPMS displays the "CHECK TIRE PRESSURE" warning message on the DIC, and at the same time illuminates the low tire pressure warning symbol.

You may notice, during cooler weather conditions, that the tire pressure monitor light, located on the instrument panel cluster, and the "CHECK TIRE PRESSURE" message will appear when the vehicle is first started and then turn off as you start to drive the vehicle. This could be an early indicator that the tire pressures are getting low and need to be inflated to the proper pressure.

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale.

The "CHECK TIRE PRESSURE" warning message and low tire pressure light (telltale) will appear at each ignition cycle until the tires are inflated to the correct inflation pressure.

The Tire and Loading Information label (tire information placard) shows the size of your vehicle's original tires and the correct inflation pressure for your vehicle's tires when they are cold.

Your vehicle's TPMS can alert you about a low tire pressure condition but it does not replace normal tire maintenance.

NOTICE: Do not use a tire sealant if your vehicle has Tire Pressure Monitors. The liquid sealant can damage the tire pressure monitor sensors.

RESETTING THE TPMS IDENTIFICATION CODES
Each TPMS sensor has a unique identification code. Any time you rotate your vehicle's tires or replace one or more of the TPMS sensors, the identification codes will need to be matched to the new tire/wheel position. Each tire/wheel position is matched to a sensor, by increasing or decreasing the tire's air pressure. The sensors are matched to the tire/wheel positions in the following order: LF TIRE (left front tire on the driver's side of the vehicle), RF TIRE (right front tire on the passengers side of the vehicle), RR TIRE (right rear tire on the passengers side of the vehicle), and LR TIRE (left rear tire on the driver's side of the vehicle).

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.

tire pressure light comes on


You shouldn't be setting the tire pressure to the max inflation pressure listed on the sidewall, that will likely result in uneven tire wear with the center of the tire wearing out prematurely. You should set the pressures according to the listings in the door jam. Most likely 32-34psi. Also, have you checked the spare tire? Some systems monitor and will illuminate the TPMS light if the spare tire pressure isn't within an acceptable range. The spare is often overlooked when checking tire pressures because of a TPMS indicator.

tire presure light stays on psi is 32 all tires 2006 scion tc site inspection reveals no nails or cuts pressure is maintained


Hello! You're problem could likely be a problem with the TPMS, or (Tire Pressure Monitoring System) - sensor. There is one in each wheel, and it's recommended that with any tire changes that they be rebuilt or replaced. I'm not sure if you've reset the tire pressure switch or not, but if you haven't and aren't familiar, the button is located inside the glove box. With the car on, press the button for 3-5 seconds and release. Turn the car off, and then back on and your light should be off.

Hope this helps and good luck! Thanks for using FixYa!
