C1581-00-Front/Rear Tire Pressure Sensor Location Undetermined

For a complete wiring diagram, refer to.

Theory of Operation

The vehicle Tire Pressure Monitoring (TPM) Sensor locate process occurs after the vehicle remains stationary for 20 minutes. The Tire Pressure Monitoring (TPM) Module will determine the Tire Pressure Monitoring (TPM) Sensor positions. The TPM Module measures the signal strength of each TPM sensor and determines if the are in the front or rear.

• When Monitored: During vehicle TPM Sensor locate process.

• Set Condition: Must fail multiple vehicle TPM sensor locate processes if localization fails due to Front/Rear fail or if the TPM module is new and has never attempted localization.






Test Step 1 - DTC STATUS IS ACTIVE

• The vehicle must remain stationary for 20 minutes before proceeding with this diagnostic procedure.

• Turn the ignition on.

• With the scan tool, read and record TPM Module DTCs.

• Test drive the vehicle at a speed greater than 24 km/h (15 mph) for 10 minutes in order to receive TPM Sensor data and allow for the system to update.

• With the scan tool, erase TPM Module DTCs.

• With the scan tool, select View DTCs in the TPM Module.

Is the DTC status Active at this time?

Yes

• Go to Test Step 2 => [ Test Step 2 - TIRE PRESSURE MONITORING (TPM) MODULE INTERFERENCE ]

No

• Go to Test Step 3 => [ Test Step 3 - INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR
DTC ]

Test Step 2 - TIRE PRESSURE MONITORING (TPM) MODULE INTERFERENCE

• Interference may occur if the TPM Module is installed incorrectly or the TPM harness is not fastened properly to the body.

• Turn the ignition off.

Verify the following:

• Aftermarket devices are installed or in the vehicle.

• The TPM Module harness is damaged or is routed incorrectly.

• The TPM Module is installed incorrectly.

Are there any of the above conditions present?

Yes

• Repair as necessary.

• Perform TPM Verification Test. Refer to => Non-DTC
Based Diagnostics. Tire Pressure Monitor Verification Test

No

• Install a new Tire Pressure Monitoring (TPM) Module.

• Perform TPM Verification Test. Refer to => Non-DTC
Based Diagnostics. Tire Pressure Monitor Verification Test

Test Step 3 - INTERMITTENT TIRE PRESSURE MONITORING (TPM) SENSOR DTC

• The conditions necessary to set this DTC are not present at this time.

• Perform any Technical Service Bulletins that may apply to this condition.

• With the scan tool, clear DTCs in the Tire Pressure Monitoring (TPM) Module.

• Test drive the vehicle for a minimum of 20 minutes with vehicle speed greater than 24 km/h (15 mph).

• With the scan tool, select View DTCs in the Tire Pressure Monitoring (TPM) Module.

Does the DTC reset or is the status Active for this DTC?

Yes

• Install a new Tire Pressure Monitoring (TPM) Module.

• Perform TPM Verification Test. Refer to => Non-DTC
Based Diagnostics. Tire Pressure Monitor Verification Test

No

• Test complete.

• Perform TPM Verification Test. Refer to => Non-DTC
