C1505-TIRE PRESSURE SENSOR 5 INTERNAL

For a complete wiring diagram Refer to Diagrams/Electrical Electrical Diagrams


Theory of Operation


The tire pressure sensor actively monitors the air pressure and air temperature inside the tire, the sensor internal battery status, and the radial acceleration of the wheel. Each sensor has a unique ID code. The sensor transmits the data at regular intervals via an encoded signal to a receiver circuit located in the Wireless Control Module (SKREEM).


- When Monitored:

With vehicle speed greater than 15 m.p.h. (24 km/h).

- Set Condition:

The WCM (SKREEM) will monitor the signals from the four active road tire sensors. A loss of signal error is detected when eight consecutive blocks of data are not received or cannot be accurately decoded. An internal sensor hardware error condition will be set when an error in the accelerometer, pressure sensor, or temperature sensor is detected.









1. OTHER DTC'S

Ignition on, engine not running.


NOTE: This fault can be set if the wrong TPM sensor was installed on the vehicle, or that the wheel has a rubber valve stem. Check to make sure the vehicle is equipped with the correct sensors.

Use a TPM-RKE Analyzer tool 9936 to scan the spare tire pressure sensor, and make sure the Sensor 5 ID matches what is programmed into the WCM. The Sensor 5 Identification is located under "Data Display" for the "WCM Wireless Control Module". If the sensor 5 ID does not match, following the programming steps outlined in the diagnostic scan tool for "Program Tire Sensor ID w/TPM Tool" under "Miscellaneous Functions" for the "WCM/Wireless Control Module" menu item.

Drive the vehicle for a minimum of 10 minutes while maintaining a continuous speed above 15 mph (24 km/h).

With the scan tool, read DTC's.

Are any other DTC's present?

Yes

- Repair all other DTC's first.

No

- With the scan tool, erase DTC's.
- Perform TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test
