Model: 2010 Hyundai Santa Fe

Symptom/Condition: The TPMS malfunction indicator lamp may be illuminated and the trouble codes C1312-C1315 (TPMS sensor RF, Radio Frequency, channel failure) may be stored if the vehicle is operating around electric power supply cables or radio transmitters at police stations, broadcasting stations, military installations, airports, transmitting towers and the like. External electronic devices connected to the vehicle’s power outlets (notebook computer, seat warmer, massager, coolers, GPS navigation, mobile phone charger, etc.) may also cause this condition.

Countermeasure/Action: The TPMS malfunction indicator light generally turns off after the vehicle is removed from such interference.

Note: In the case of the TRW TPMS, the TPMS indicator lamp turns off after the vehicle is removed from the interference and the ignition switch is turned off and on.

C1312-C1315 (TPMS initiator RF channel failure) set condition

• If the TPMS sensor learning fails or no RF signal is transmitted from the learned TPMS sensor while driving the vehicle for 25 minutes over 12 mph, the trouble codes C1312, C1313, C1314 or C1315 will be set. In addition, as mentioned above, the trouble codes may be set by electromagnetic interference with the TPMS.

• Check communication between the TPMS sensors and a scan tool. If a TPMS sensor does not transmit any data to the scan tool, replace the TPMS sensor.

• If all four TPMS sensors are checked and working correctly, trace the cause of electromagnetic interference. Drive the vehicle out of the strong electric field or remove the external electronic devices that may cause the condition. Drive the vehicle for about five minutes to verify that the condition is corrected.
