DTC Troubleshooting
Tire Low Air Pressure
NOTE: If low tire pressure is detected, the control unit
sets one or more of these DTCs, and turns on the low
tire pressure indicator. If the low tire pressure indicator
comes on because of a low tire pressure, and the client
corrects it before bringing the vehicle in, the DTCs will
be stored, but the indicator turns off. 1. Turn the ignition switch to LOCK (0).
2. Make sure the tires are inflated to the specified tire pressure listed on the doorjamb sticker.
3. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
The system is OK at this time. Check for and
repair the cause of air loss.
Go to step 4.
4. Check for DTCs with the HDS. 5. Note the tire pressure sensor(s) number by the
indicated DTC.
11 No. 1
13 No. 2
15 No. 3
17 No. 4
6. Do the tire pressure sensor location procedure to determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
7. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS,
and compare it with the actual measured tire
pressure.
Go to step 8.
Replace the appropriate tire pressure sensor
(see page 18-76).
8. Clear the DTC with the HDS.
9. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
10. Check for DTCs with the HDS.
Replace the TPMS control unit (see page
18-75).
If any other DTCs are indicated, troubleshoot
the appropriate DTC. If no DTCs are indicated, the
system is OK at this time.

Symptom Troubleshooting
NOTE: Check for gauge DTCs with the HDS (see page
22-3). If gauge DTCs are stored, troubleshoot those
DTCs first.
1. Turn the ignition switch to ON (II).
2. Check the low tire pressure indicator for several seconds when the ignition switch is turned ON (II).
Go to step 3.
Do the troubleshooting for the gauge control
module (see page 22- 241). If necessary, substitute a
known-good gauge control module (see page
22-277), and recheck.
3. Test-drive the vehicle at 45 km/h (28 mph) or more for at least 1 minute.
4. Stop the vehicle, and lower the pressure in each tire until the low tire pressure indicator comes on
(see table).
NOTE: Reinflate the tire before continuing to the next tire.
 After noting whether the low tire pressure indicator came on, make sure it goes off when
you reinflate the tire before proceeding to the
next tire.
 If 5 minutes has passed since finishing the last test-drive, reactivate the appropriate tire
pressure sensor using the TPMS sensor initializer
tool (see page 18-53).
16 inch wheels 175 kPa (1.8 kgf/cm , 25 psi)
17 inch wheels 183 kPa (1.9 kgf/cm , 27 psi)
The system is OK at this time.
Go to step 5. 5. Do the tire pressure sensor location procedure to
determine the affected tire location and relate it to
the tire pressure sensor number (see page 18-53).
Go to step 6.
Check that the tire pressure sensor is properly
mounted. If necessary, replace the appropriate tire
pressure sensor (see page 18-76).
6. Check the TIRE 1, TIRE 2, TIRE 3, or TIRE 4 AIR PRESSURE in the TPMS DATA LIST with the HDS,
and compare with the actual measured tire
pressure.
Go to step 7.
Replace the appropriate tire pressure sensor
(see page 18-76).
7. Turn the ignition switch to LOCK (0).

1. Turn the ignition switch to LOCK (0).
2. Remove the driver’s dashboard undercover (see page 20-103).
3. Disconnect the TPMS control unit connector (A).
4. Remove the TPMS control unit (B) from the bracket (C).
NOTE: To disconnect the TPMS control unit from its
bracket, insert a small flat-tipped screwdriver
between the TPMS control unit and the bracket
shown in (D) to release the hook, then slide out the
TPMS unit.
5. Replace the bracket if necessary. 6. Install the new TPMS control unit in the reverse
order of removal.
NOTE: Make sure the TPMS control unit is properly
installed. You will hear a click when the TPMS
control unit is securely mounted on the bracket.
7. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).

1. Raise the vehicle, and support it with safety stands in the proper locations (see page 1-11).
2. Remove the wheel with the faulty sensor.
3. Remove the tire valve stem cap and the valve stem core, to deflate the tire.
4. Remove any balance weights, and then break the bead loose from the wheel with a commercially
available tire changer (A).
Note these items to avoid damaging the tire
pressure sensor: Do the outside of the wheel first.
 Position the wheel as shown so the valve stem (B) is 90 degrees from the bead
breaker (C) as shown.
 Do not position the bead breaker of the tire changer too close to the rim. 5. Position the wheel so the tire machine (A) and tire
iron (B) are next to the valve stem (C), and will
move away from it when the machine starts. Then
remove the tire from the wheel.
6. Remove the valve stem nut (A) and the washer (B), then remove the tire pressure sensor with the valve
stem (C) from the wheel.
NOTE: Check the nut and the washer, If they have
deterioration or damage, replace then with new
ones during reassembly.
