C151C-TIRE PRESSURE MONITORING (TPM) SENSORS MISSING



Theory of Operation

When installing a new Wireless Ignition Node (WIN), the module is programed with universal IDs for the Tire Pressure Monitoring (TPM) Sensors. The WIN must be programmed with the correct TPM Sensor IDs.

For a detailed description of the Tire Pressure Monitoring (TPM) system, Tire Pressure Monitoring (TPM) - Description

For additional information regarding the Tire Pressure Monitoring (TPM) system, Tire Pressure Monitoring (TPM) - Operation.

- When Monitored:
During vehicle TPM Sensor ID locate process.

- Set Condition:
When installing a new Wireless Ignition Node (WIN).





1. VERIFY DTC IS ACTIVE

NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WIN fault. Interference from other elements over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.

1. Correct all tire pressures to the recommended cold inflation tire pressure specifications and wait two minutes for the system to update.
2. Ignition on, engine not running.
3. With the scan tool, record and erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for 10 minutes, in order to receive TPM data and allow for the system to update.
5. With the scan tool, read DTCs.

Is the DTC status Active at this time?

Yes

- Go To 2

No

- Go To 5

2. TPM-RKE ANALYZER 9936 TOOL

Is there a TPM-RKE Analyzer tool available?

Yes

- Go To 3

No

- Go To 4

3. WITH TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR ID(S)

NOTE: Always be certain to select the proper vehicle line and model year when using this tool, as the tool will automatically use the correct protocol to attempt to read the TPM Sensor. If the incorrect vehicle line and/or model year is selected, the TPM Sensor will not respond to the tool.

NOTE: If you receive no response from any of the tire pressure sensors, check to make sure that the TPM-RKE Analyzer is set correctly and repeat the process on each of the non-responsive wheel(s)

1. Use a TPM-RKE Analyzer tool to scan each TPM Sensor for an ID. Store in the proper location in the TPM-RKE Analyzer tool.
2. Use a TPM-RKE Analyzer tool, to upload the correct IDs and proper locations in the scan tool.
3. With the scan tool, select the TIPM, under "Miscellaneous Functions", follow the procedure for uploading TPM Sensor IDs.
4. With the scan tool, erase DTCs.
5. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for 10 minutes in order to receive the TPM data and allow for the system to update.
6. With the scan tool, check to see if the TPM Sensor IDs match what is programmed into the WIN.

Do the TPM IDs match?

Yes

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.

No

- Replace the Wireless Ignition Node (WIN). Wireless Ignition Node Receiver - Removal.
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.

4. WITHOUT TPM-RKE TOOL CHECK TIRE PRESSURE MONITORING (TPM) SENSOR ID(S)
1. Starting with the left front wheel, deflate the tire to 20 psi (138 kPa), wait two minutes and check the scan tool for changes to any compensated tire pressure values.
2. Repeat the above step on each wheel of the vehicle.
3. With the scan tool, erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for 10 minutes in order to receive the TPM data and allow for the system to update.
5. With the scan tool, check to see if the TPM Sensor IDs are programmed into the WIN.

Are the TPM Sensor IDs in the WIN?

Yes

- Test complete.
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.

No

- Replace the Wireless Ignition Node (WIN).
- Perform the TPM VERIFICATION TEST. Tire Pressure Monitor (TPM) Verification Test.

5. INTERMITTENT TIRE PRESSURE SENSOR DTC

NOTE: The DTC can be caused by many different factors and might not be a sensor/transmitter or a WIN fault. Interference from other elements over power the sensor/transmitter RF frequency making erratic operation to the TPM system. Check the vehicle for aftermarket accessories that could compromise the RF frequency signal before diagnosing the TPM system.

1. The conditions necessary to set this DTC are not present at this time.
2. Perform any TSBs that may apply to this condition.
3. With the scan tool, erase DTCs.
4. Test drive the vehicle at a speed greater than 24 km/h (15 mph) for 10 minutes in order to receive TPM data and allow for the system to update.
5. With the scan tool, read DTCs.

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

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
