DTC 32,34,36,38: Tire Pressure Sensor Signal Failure

WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. 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 charger, etc) interfering with the RF signal from the sensors when turning the ignition switch is ON (II), or press the engine start/stop button to select the ON mode
  • Vehicle must be driven for 3 minutes at 15 mph (24 km/h) or more for DTC 32,34,36, or 38 to set
  1. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  2. Check the DTC indicated to the tire location to make sure the wheel is a TPMS type with the tire pressure sensor

    Is a TPMS type wheel 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) continuously for 40 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's speed indicated? 

    YES  -Go to step  10

  5. Clear the DTC with HDS.
  6. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
  7. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  8. Wait about 5 seconds.
  9. 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

  10. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
  11. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  12. Check TPMS DATA LIST for RF, LF, RR, or LR TIRE PRESSURE SENSOR STATUS changes to NORMAL with the HDS
    NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, rotate the tire 1/4 turn, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and try again If UNDEFINED is still displayed, repeat the procedure in the previous sentence until NORMAL is shown

    NO  -Go to step 13

  13. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
  14. Substitute a wheel with a known-good tire pressure sensor on the vehicle
  15. To 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 )
  16. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
  17. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  18. Check TPMS DATA LIST for RF, LF, RR, and LR TIRE PRESSURE SENSOR STATUS changes to NORMAL with the HDS
    NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, rotate the tire 1/4 turn, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, 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  -Replace the tire pressure sensor on the original wheel (see REAR )

    NO  -Go to step 19

  19. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode
  20. Substitute an initiator from a known-good location on the current vehicle, or from another known-good vehicle (see INITIATOR REPLACEMENT )
  21. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode
  22. Check TPMS DATA LIST for RF, LF, RR, and LR TIRE PRESSURE SENSOR STATUS changes to NORMAL with the HDS
    NOTE: If UNDEFINED is shown on the sensor transmitter status, turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, rotate the tire 1/4 turn, then turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, and try again If UNDEFINED is still displayed, repeat the procedure in the previous sentence until NORMAL is shown
