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
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
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.
