Tire Pressure Monitor (TPM) System

NOTE: If vehicle is equipped with Tire Pressure Monitor (TPM) system, the tire air valve will be Silver.

The Tire Pressure Monitoring System (TPMS) is controlled by BCM and works as follows. TPMS monitors the air pressure in each tire except the spare tire. It consists of a low tire pressure warning light, tire pressure sensors, TPMS receiver and BCM . As the tire revolves (at a vehicle speed of approximately 25 mph (40 km/h) or more), the tire pressure sensor installed to each wheel transmits the tire pressure data through the TPMS receiver to BCM. When the tire pressure is lower than the standard value in the module, BCM makes the low tire pressure warning light in the combination meter light up to warn the driver that the tire pressure has decreased. Also, when anything faulty is detected in TPMS, it makes the low tire pressure warning light stay on after blinks for 75 seconds to warn the driver that there is something faulty in the system. Operations of the tire pressure sensor, TPMS receiver, BCM and low tire pressure warning light are described below. The Tire Pressure Monitor (TPM) system is designed to detect when one or more tires is significantly underinflated. A tire pressure sensor containing a unique identification code is mounted on each wheel. The sensors transmit tire pressure signals to a central receiver, which relays the information to the Body Control Module (BCM).

NOTE: Only up to 4 ID codes of the tire pressure sensor can be registered in TPM system controller. The TPM system controller is not, by default, programmed to recognize the ID code of the tire pressure sensor in the spare tire. The ID must be registered into the system before it will become active.

Under the following conditions, the system may not function properly:

When a spare tire is in use.
When the spare tire is included in a tire rotation.
When a wheel not containing a tire pressure sensor is installed.
When tire pressure sensor is damaged during tire replacement.
The tire pressure sensor battery is exhausted.
If tire pressure sensor has been replaced, and retraining procedure has not been performed.
If liquid sealants are used to repair a flat tire.
If electric devices or facilities using similar radio wave frequencies are nearby.
A lot of snow or ice covers the vehicle, particularly around the wheels or wheelhousings.
Snow tires or tire chains are used.
When non-genuine SUZUKI wheels or tires are used.
When tires other than specified size are used.
