No: TSB-11-31-004DATE: November, 2011
MODEL: See below
SUBJECT:
DTCS 22, 26, 31, 35, 39, C1911, C1921, C1931, C1941 - TPMS SENSOR ID RECEPTION
PURPOSE
Customers of some affected vehicles may report the TPMS warning light is illuminated. You may find one or more of the subject DTCs recorded in TPMS receiver memory (two digit codes are for 2004-2006 vehicles). The TPMS sensor may not be malfunctioning. Certain other factors must be considered prior to sensor replacement.
These DTCs may set if the receiver does not receive TPMS sensor data normally. Some external electronic devices (mobile phone charger, GPS devices, iPod accessories, etc.) transmit RF signals when connected to the 12 volt power outlet and interrupt the TPMS sensor signal. A wireless transmission facility or device using the same frequency as the transmitter may also cause signal interruption. Under these conditions, a DTC may be set and the TPMS light is illuminated.
This TSB provides a repair procedure to correct this condition.
AFFECTED VEHICLES
2004-2011 Endeavor
2006-2012 Galant
2008-2012 Eclipse
2008-2012 Eclipse Spyder
PROCEDURE
1. Unplug any aftermarket device from the 12V power outlet. If none are present or the customer claims one is not used, inquire if they regularly drive past a transmitter (radio or TV station, airport, military installation, etc).
2. Using MUT-III, check for DTCs.
3. Retrieve and record all tire pressure sensor IDs registered to the vehicle.
4. Complete the Tire Pressure Sensor ID Registration" procedure as described in "Group 31 - Wheel and Tires" in the service manual.
5. Compare the TPMS sensor IDs to those recorded in step 3. If the sensor IDs ARE NOT the same as what you recorded, it may indicate:
^ a wheel exchanged with one from another vehicle.
^ a sensor was replaced and the new part was not registered to the vehicle.
Correcting DTCs described by these and other similar examples are non-warrantable repairs.
6. If the sensor IDs ARE the same as step 2 a brief signal interruption may have blocked the TPMS sensor signal.
DO NOT REPLACE THE TPMS SENSOR OR RECEIVER. Proceed to step 7.
7. Erase DTCs from the TPMS system. Return the vehicle to the customer and advise them to relocate or unplug any aftermarket devices that can cause radio frequency interference.
8. Refer to TSB-11-31-001 for general TPMS service information.
Contact Techline if you have difficulty erasing DTCs or registering sensors.
