Service tire monitor system message and light on dash...just --- for pressure readings for all tires. is there a fuse for the Tire Monitor System??

If the BCM detects a low tire pressure condition, a variation in pressure between 2*tires on the same axle, or a malfunction in the system, it will send a serial data message to the instrument cluster. Hope this helps!

Not giving any codes. ????? What type code reader did you use ? Is it able to read ABS codes ? Check codes in the BCM - body control modules , instrument cluster , all the modules on the vehicle . You put a 15 amp fuse in where a 10 amp goes ? Good way to set your vehicle wiring on fire. Fuse blows , has a short to ground .Sounds like you have some major electrical issues . Do you know what a electrical wiring diagram is an how to use it to pin point testing areas in a electrical circuit . What a DVOM - digital volt ohmmeter is an how to use it ? The Tire Pressure Monitor (TPM) system alerts the driver when a large change in tire pressure exists while the vehicle is being driven. The TPM system uses the Electronic Brake Control Module (EBCM), Antilock Brake System (ABS) wheel speed sensor inputs, class 2 serial data circuit, Systems monitor, or the Driver Information Center (DIC) (if equipped) to perform the system functions. The EBCM contains software to calculate relative tire pressure differences. The software requires approximately 30 minutes of straight line driving in three different speed ranges to complete the calibration process to have full capability for detecting a tire pressure condition.
Your best bet , take your vehicle to a qualified repair shop that has the proper diagnostic skills to find an fix the problem .

The body control system consists of the following 3 modules:
• The dash integration module (DIM)
• The instrument panel integration module (IPM)
• The rear integration module (RIM)
Each of the 3 body control modules integrate a number of functional systems under the control of a single module. Each of the modules are connected to the Class 2 serial data line; many control signals are implemented by Class 2 messages.

Check tire pressure if pressure is ok..the pressure monitors in each wheel is probably finished or near finished. Each tire pressure monitor module is part of the air valve. It is located inside the wheel. A tiny watch size battery is in each and reports the pressure to the dash module. As the battery wears out the reporting becomes erratic or not at all and the dash light starts to flash. You have to replace the tire monitor in the offending wheel as the battery is sealed inside each air valve monitor . This involves removing the tire from the wheel replacing the air valve pressure monitor and remounting and balancing the wheel. You must also recalibrate the system.. ( In you car Manuel). Each monitor runs about 25-50bucks.. You can find them sometimes on amazon.com

It means you have a malfunction in the TPMS system. First you can try to do a reset as follows: 1. key on, engine off, parking brake on. 2. turn park lights on and off 4 times you will hear a horn chirp twice, you are in program mode. Start at L/F tire release air for 10 seconds, wait 15 seconds until horn chirp, after chirp go to R/F tire do the same until horn chirp then R/R let air out til the chirp then L/R do the same after the L/R chirp, turn key off and you are done, note you have only 5 min. to complete. If you do not hear horn chirp at each tire, you will have to start from beginning. When complete, remember to add air to each tire, 35 psi is recommended.
If that does not work you probably have a bad TPMS sensor, which will have to be replaced. Some auto parts stores will test your sensors for free, so check around.

you have a low tire...the vehicle has a sensor to read the tires pressure..just air tires up to recommended pressure and light will go off.

Hello Mattingly.

Here is some information for you regarding your problem.

The Tire Inflation Monitor (TIM) system alerts the driver when the pressure changes in one of the tires. The system only detects a low pressure condition while the vehicle is being driven. Once a low tire pressure condition is detected, the system informs the driver that a low tire pressure condition exist's, whenever the ignition is ON.
The LOW TIRE message appears on the Instrument panel if the tire pressure in one tire becomes at least 82 kPa (12 psi) lower or higher than the other three tires. The message does not appear if more than one tire is low or high, or if the system is not calibrated properly. The system does not inform the driver which tire is low. To clear this message, set the tire pressures in all four tires to the proper pressures and perform the system reset procedure. Refer to Tire Inflation Monitor Reset Procedure for service procedure.
The Tire Inflation Monitor software requires approximately one half hour of straight line driving to complete the TIM autolearn. There are several speed ranges that the EBCM needs to learn the tire inflation configuration in order to have the full capability of detecting a low tire condition. The speed detection ranges are the following:

• 24-64 km/h (15-40 mph)
• 64-113 km/h (40-70 mph)
• 113-145 km/h (70-90 mph)

Each speed range has 2 modes of low tire detection.

• Monitor Mode 1
• Monitor Mode 2 The EBCM learns the tire inflation configuration for each speed range independently. In Monitor Mode 1, the EBCM has only partially learned the tire inflation configuration for the speed range and has limited detection capability for a low tire condition. In Monitor Mode 2, the EBCM has fully learned the tire inflation configuration for the speed range and has full detection capability for a low tire condition. If the EBCM is not in Monitor Mode 1 or Monitor Mode 2, a low tire condition cannot be detected because the EBCM has not learned the tire inflation configuration of the vehicle.

To reset (calibrate) the system:
Turn the ignition switch to RUN. Then press and hold the RESET button for about five seconds. The red RESET button is located inside the instrument panel fuse block on the right side of the dash.. The LOW TIRE light will come on and flash three times and then it will turn off.
The system completes the calibration process during driving.
The system normally takes 15 to 20 minutes of driving in each of three speed ranges to "learn" tire pressures. The speed rages are 15 to 40 mph (25 to 65 km/h), 40 to 65 mph (65 to 105 km/h) and above 65 mph (105 km/h).

There you are, this should fix you up.
Keep in mind this system uses wheel speed sensors to calculate. If one of your sensors isn't working your low tire light will remain on.

Sensors are rf transmiters and the door lock module is the reciever this information is the sent to the body control module and then to the display on dash. Is only tire pressure monitor having a problem?

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.

Hello and welcome. this requires a high end scan tool to check. but since the left front tire does read any pressure. this is usually a bad tire pressure sensor. this is probably why the service tire pressure light is on. the sensor is mounted on the tire stem inside the wheel. this requires the tire to be removed from the wheel to replace sensor

You can see if the dealer can turn the tire monitor system off, but that would be your only hope, or ignore it like everyone else does.
