Tire Pressure Monitor Warning Indicators
NOTE:
As ambient temperature decreases by 6°C (10°F), tire pressure decreases 1 psi (7 kPa). If tire pressures are not adjusted at cold temperature, the tire pressure may drop enough to be detected by the TPM system, which will activate the low pressure warning light.
When the tire pressure warning light comes on solid and message center displays "LOW TIRE PRESSURE", check the air pressure of all tires and adjust to the specified cold pressure listed on vehicle certification label (found on driver's door or door pillar). Drive the vehicle at 20 mph (32 km/h) for at least 2 minutes. Make sure the warning light goes off. If the warning light stays on, there is a malfunction in the TPM system. See appropriate manufacturer service information.
The TPMS warning indicator flashes for 70 seconds, then remains on continuously when the ignition is turned to the ON position if the TPMS is malfunctioning. The following messages indicate a system malfunction:
- Tire Pressure Sensor Fault - The message center displays TIRE PRESSURE SENSOR FAULT when a TPMS sensor is malfunctioning.
- No communication with the BCM - The TPMS warning indicator illuminates when the IPC has not received any signals from the BCM for more than 5 seconds. The message center displays TIRE PRESSURE MONITOR FAULT.
- Tire Pressure Monitor Fault - The message center displays TIRE PRESSURE MONITOR FAULT when the TPMS is malfunctioning.
