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.
Does the low tire pressure indicator go of f ? Is the indicated tire pressure on the HDS within40 k Pa ( 0.4 k gf / cm , 6 psi ) of t he act ual t i r epr essur e?

Tire Pressure Sensor
Abnormally High Temperature
1. Turn the ignition switch to LOCK (0).
2. Make sure the tires have cooled down.
NOTE: An abnormal rise in the internal temperature
of the tires can be caused by Excessive braking
Failure to release the parking brake (rear tires only)
Leaving the vehicle r unning while parked (front
tires only)
Improper assembly of a wheel and tire
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. Clear the DTC
with the HDS.
Go to step 4.
4. Check for DTCs with the HDS.
5. Note the tire pressure sensor(s) number by the indicated DTC.
21 No. 1

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 TEMPERATURE in the TPMS DATA LIST with the
HDS.
Replace the appropriate tire pressure sensor

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.
Check for loose terminals and poor
connections at the TPMS control unit. If necessary,
substitute a known-good TPMS control unit
(see page 18-75), and recheck.
If any other DTCs are indicated, troubleshoot
the appropriate DTC. If no DTC are indicated, the
system is OK at this time.

Without ABS, when the brake pedal is pressed while driving, the wheels sometimes lock before the vehicle comes to a
stop. In such an event, the maneuverability of the vehicle is reduced if the front wheels are locked, and the stability of
the vehicle is reduced if the rear wheels are locked, creating an extremely unstable condition. With ABS, the system
precisely controls the slip rate of the wheels to ensure maximum grip force from the tires, and it thereby ensures
maneuverability and stability of the vehicle. The ABS calculates the slip rate of the wheels based on the four wheel
speeds, and then it controls the brake fluid pressure to reach the target slip rate.
The control unit detects the wheel speed based on the wheel speed sensor signals it receives, then it calculates the
vehicle speed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration
based on the wheel speeds.
The control unit calculates the slip rate of each wheel, and transmits the control signal to the modulator unit solenoid
valve when the slip rate is high.
The hydraulic control has three modes: Pressure intensifying, pressure reducing, and pressure retaining.
