DTC 41: Abnormal Signal Reception Error

WARNING: This page is about a different car, the 2008 Acura TL and 2007 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.
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 (see MEMORIZING THE TIRE PRESSURE SENSOR ID  ).
  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 (see DTC 85: F-CAN COMMUNICATION FAILURE  ).

    NO  -Check for loose terminals and poor connections at the TPMS control unit. If necessary, substitute a known-good TPMS control unit (see TPMS CONTROL UNIT REPLACEMENT  ) 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 (see TPMS CONTROL UNIT REPLACEMENT  ) and recheck.
