DTC 41: Abnormal Signal Reception Error

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • Inspect for an aftermarket electrical device(s) (such as an inverter, battery changer, etc) interfering with the RF signal from the sensors when turning the ignition switch to ON (II).
  • If DTC 32, 34, 36, or 38 is also set, troubleshoot those DTCs first.
  1. Turn the ignition switch to LOCK (0).
  2. 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 3.

    NO  -Install a TPMS type wheel, and memorize the sensor ID. Drive the vehicle above 15 mph (24 km/h) for 40 continuous seconds, or memorize the ID with the HDS (see MEMORIZING THE TIRE PRESSURE SENSOR ID ). ■

  3. Test-drive the vehicle.
  4. 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.

  5. Clear the DTC with the HDS.
  6. Turn the ignition switch to LOCK (0).
  7. Turn the ignition switch to 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 to LOCK (0).
  10. Turn the ignition switch to ON (II).
  11. Check TPMS DATA LIST for LF, RF, LR, and RR TIRE PRESSURE SENSOR STATUS changing to NORMAL with the HDS.
    NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), rotate the tire 1/4 turn, then turn the ignition switch to ON (II), and try again. If UNDEFINED is still displayed, repeat the procedure in the previous sentence until NORMAL is shown.

    Is NORMAL indicated within one full turn of the tire? 

    YES  -Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting (see INTERMITTENT FAILURES ).

    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. ■
