DTC 41: Abnormal Signal Reception Error

NOTE: Inspect for an aftermarket device interfering with the RF signal from the sensors when turning the ignition switch ON (II).

1. Check all four wheels to make sure they are the TPMS type with the tire pressure sensor.
Is each wheel a TPMS type with a tire pressure sensor mounted on the vehicle?

YES - Go to step 4.

NO - Go to step 2.

2. Install known-good TPMS wheel(s).
3. To memorize the sensor ID(s), drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID(s) with the HDS.
4. Test-drive the vehicle.
5. Check the VSP 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.

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 TPMS DATA LIST for LF, RF, LR, RR sensor status changing to "NORMAL".

NOTE: If the HDS screen shows not defined for sensor status, turn the ignition switch OFF, rotate the tire 1/4 turn, then turn the ignition switch ON (II), and try again. If not defined is still shown, repeat the procedure in the previous sentence until NORMAL is shown.

Is NORMAL indicated within 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.
