Description

DESCRIPTION





NOTE: On vehicles equipped with Tire Pressure Monitoring System, one tire pressure sensor (6) is mounted to each wheel in place of the traditional tire valve stem. Each sensor has an internal battery that lasts up to 10 years. The battery is not serviceable. At the time of battery failure, the sensor must be replaced. The TPM system operates on a 315 or 433 MHz radio frequency. The 315 MHz sensors can be easily identified by a black sensor body, with (an oval insignia) (1). The 433 MHz sensors can be identified by a grey sensor body with an oval insignia.

NOTE: If replacing the WCM, the spare tire must be dismounted from its wheel to access and note the spare tire pressure sensor ID. Then follow the programming steps outlined in the diagnostic scan tool for "Learn Spare Tire Sensor ID" under Miscellaneous Functions for the WCM wireless control module menu item as appropriate. In addition, the placard pressure thresholds must be updated in the new WCM. Go to "Update Pressure Thresholds" under Miscellaneous Functions for the WCM wireless control module and follow the procedure.

On vehicles equipped with Tire Pressure Monitoring System, one tire pressure sensor (6) is mounted to each wheel in place of the traditional tire valve stem. Each sensor has an internal battery that lasts up to 10 years. The battery is not serviceable. At the time of battery failure, the sensor must be replaced.

The TPM system operates on a 315 MHz radio frequency. The 315 MHz sensors can be easily identified by a black sensor body, with (an oval insignia) (1) and a grey valve cap (2).

The Export TPM system operates on a 433 MHz radio frequency. The 433 MHz sensors can be easily identified by a gray sensor body (with an oval insignia) and a black valve cap (2).

CAUTION: Although 315 MHz and 433 MHz sensors are identical in size and shape, they are not interchangeable. Always make sure the correct sensor is being used.

NOTE: Domestic vehicles, use the 315 MHz TPM sensors with the BLACK sensor body. For Export vehicles, use the 433 MHz TPM sensors with the GREY sensor body. Although 315 MHz and 433 MHz sensors are identical in size and shape, they are not interchangeable. Always make sure the correct color sensor is being used. A RKE-TPM Analyzer can be used to determine the sensor's frequency without having to dismount the tire.

NOTE: If aftermarket wheels are installed and do not contain tire pressure sensors, the system will not function properly and the driver will be continuously notified of a system malfunction.

The TPM sensors are designed for original style factory wheels. It is not recommended to install a tire pressure sensor in an aftermarket wheel. (This could cause sealing and system performance issues).





The serviceable components of the tire pressure sensor are:

- Sensor-To-Wheel Seal (4)
- Valve Stem Cap (2)
- Valve Stem Core
- Valve Stem Nut (3)

The valve stem caps and cores used are specifically designed for the tire pressure monitoring sensors. Although similar to standard valve stem caps and cores, they are different. The valve stem cap has a special seal inside to keep moisture and corrosion out. The valve stem core has a special nickel coating to protect from corrosion.
