DTC 41: Abnormal Signal Reception Error

NOTE: Inspect for an aftermarket device interfering with the RF signal from the sensors when driving the vehicle.

1. Turn the ignition switch OFF.
2. Make sure all four wheels are TPMS wheels with tire pressure sensors.
Are TPMS type wheels with tire pressure sensors mounted on the vehicle?
YES - Go to step 5.
NO - Go to step 3.

3. Install a known-good TPMS wheel.
4. Memorize the tire pressure sensor ID with the HDS.
5. Turn the ignition switch ON (II).
6. Check the Tire 1, Tire 2, Tire 3, or Tire 4 Pressure Sensor Transmitter Status in the TPMS DATA LIST with the HDS and the TPMS sensor initializer tool.

NOTE: If Not defined is shown on the HDS, turn the TPMS sensor initializer tool OFF, rotate the tire 1/4 turn, then turn the TPMS sensor initializer tool ON, and try again. If Not defined is still shown, repeat the procedure in the previous sentence until a response is shown.

Is NORMAL indicated for one tire or more within one full turn of the tire?
YES - If any DTCs are indicated, troubleshoot the appropriate DTC. If no DTC are indicated, the system is OK at this time.
NO - Check for loose terminals and poor connections at the TPMS control unit and G502. If necessary, substitute a know-good TPMS control unit, and recheck.
