DTC 41: Abnormal Signal Reception Error

NOTE: Inspect for an aftermarket electrical device that may produce RF signals. This may interfere with the signals from sensors.

1. Turn the ignition switch OFF.
2. Check all four wheels to make sure they are the TPMS type with the tire pressure sensor properly mounted in each one.

Is each tire pressure sensor mounted properly?

YES - Go to step 10.

NO - Go to step 3.

3. Install known-good TPMS wheel(s).
4. To memorize the new sensor ID(s), drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID(s) with the HDS.
5. Test-drive the vehicle, and check the VEHICLE SPEED in the TPMS DATA LIST with the HDS.

Is the vehicle speed indicated?

YES - Go to Step 9.

NO - Go to Step 6.

6. Turn the ignition switch OFF.
7. Turn the ignition switch ON (II).
8. Check for DTCs with the HDS.

Is DTC 85 indicated?

YES - Go to the DTC 85 troubleshooting. DTC 85

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit and recheck.

9. Turn the ignition switch OFF.
10. Turn the ignition switch ON (II).
11. Check that all the wheels are transmitting signals with the HDS.

NOTE: If UNDEFINED is shown on sensor transmitter status, turn the ignition switch OFF, rotate the appropriate tire 1/4 turn, then turn the ignition switch ON (II), and try again. If UNDEFINED is still displayed, repeat the procedure in the previous sentence until a response is shown.

Is there at least one response from each wheel, in one full turn of the tire?

YES - The system is OK at this time. Clear the DTC with the HDS.

NO - Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit and recheck.
