1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
 The stall speed tests should be used for diagnostic purposes only.
 Stall speed test results should be the same with the shift lever in D, S, and R.
 Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the

Wheel Alignment
The suspension can be adjusted for front camber, front
toe, and rear toe. However, each of these adjustments
are related to each other. For example, when you adjust
camber, the toe will change. Therefore, you must adjust
the front wheel alignment whenever you adjust camber
or toe.
For proper inspection and adjustment of the wheel
alignment, do these checks: 1. Release the parking brake to avoid an incorrect measurement.
2. Make sure the suspension is not modified.
3. Make sure the fuel tank is full, and that the spare tire, the jack, and the tools are in place on the
vehicle.
4. Check the tire size and tire pressure.
5. Check the runout of the wheels and tires (see page 18-9). 6. Check the suspension ball joints (Hold a tire with
your hands, and move it up and down and right and
left to check for movement).
7. Before doing alignment inspections, be sure to remove all extra weight from the vehicle, and no
one should be inside the vehicle (driver or
passengers).
8. Bounce the vehicle up and down several times to stabilize the suspension.
9. Check that the steering column is set at the center tilt and telescopic position.
Use commercially available computerized four wheel
alignment equipment to measure wheel alignment
(caster, camber, toe, and turning angle). Follow the
equipment manufacturer’s instructions. 1. Check the caster angle.
 If the measurement is within specifications,measure the camber angle.
 If the measurement is not within specifications, check for bent or damaged suspension
components.

All four tire pressure sensor IDs must be memorized to
the TPMS control unit whenever you do any of these
actions: Replace the TPMS control unit.
 Replace the tire pressure sensor.
 Substitute a known-good wheel with tire pressure sensor.
NOTE:  To ensure the control unit memorizes the correct ID, the vehicle with the new sensor must be at least 3 m
(10 ft) away from other vehicles that have tire
pressure sensors.
 When doing a tire rotation, memorizing the sensors in not needed.
1. With the ignition switch in LOCK (0), connect the HDS to the data link connector (DLC) (A) located
under the driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the TPMS control unit. If it doesn’t,
troubleshoot the DLC circuit (see page 11- 204).
4. Select Sensor ID Learning from the mode menu on the HDS. 5. Turn on the TPMS tool by pressing the green select
button. Press the green select button until the
proper light sequence is illuminated as per the tool
user’s manual.
6. Hold the TPMS tool near one wheel, memorize the tire pressure sensor ID by following the screen
prompts on the HDS.
NOTE: If you turn the ignition switch to LOCK (0) before memorizing all four sensor IDs, the memorizing
ID is canceled.
 See the HDS Help menu for specific instructions.
7. Repeat step 6 for each wheel until all four sensor IDs are memorized. When all four IDs are
memorized, the low tire pressure indicator blinks.

Once the vehicle speed exceeds 45 km/h (28 mph), the TPMS control unit monitors all four tire pressure sensors and
the system function. If it detects low pressure in a tire, it alerts the driver by turning on the low tire pressure indicator.
If it detects a problem in the system, it turns on the TPMS indicator.
Mounted inside of the dash, the TPMS control unit receives wireless pressure sensor ID signals
every time the vehicle
speeds exceeds 45 km/h (28 mph). It also receives wireless signals from the transmitters for tire pressure and the
sensor condition, and it continuously monitors and controls the system. The TPMS control unit cannot directly
determine the position (location) of a tire pressure sensor(s) on the vehicle since it is a wireless system. TPMS sensor
locations will change during scheduled vehicle maintenance (tire rotation).
NOTE: To determine the actual location of each TPMS wheel sensor on the vehicle, do the tire pressure sensor
location procedure (see page 18-53). Once the tire pressure sensor locations are identified, write the sensor ID on the
side wall of the tire with a tire crayon to eliminate confusion.
Two indicators are in the gauge control module (tach): The low tire pressure indicator comes on when any tire
pressure is low, and the TPMS indicator that comes on only if there’s a problem with the system.
The low tire pressure indicator alerts the driver that a tire(s) pressure is low, but does not specify the tire(s) location.

Symptom Troubleshooting
NOTE: Make sure that the caliper pins are installed
correctly.
Upper caliper pin B and lower caliper pin A are different.
If the pins are installed in the wrong location, it will
cause vibration, uneven or rapid pad wear, and
possibly uneven tire wear. For proper caliper pin
location: Except Type S model (see page 19-22), Type S
model (see page 19-23).
1. Drive the vehicle until the brakes drag or until the pedal is high and hard. This can take 20 or more
brake pedal applications during an extended test-
drive.
2. With the engine running, raise the vehicle on a lift, and spin all four wheels by hand.
Go to step 3.
Look for other causes of pad wear, high pedal,
or vehicle vibration.
3. Turn the ignition switch to LOCK (0), press the brake pedal several times to deplete the vacuum in
the brake booster, and then spin the wheels again
to check for brake drag.
Go to step 4.
Replace the brake booster (see page 19-27).
4. Without removing the brake lines, unbolt and separate the master cylinder from the brake
booster, then spin the wheels to check for brake
drag.
Go to step 5.
Check the brake pedal position switch
adjustment, and pedal free play (see page 19-6). 5. Loosen the hydraulic lines at the master cylinder,
then spin the wheels to check for brake drag.
Go to step 6.
Check the master cylinder reservoir for
contamination in the brake fluid. If you find
contamination, flush the entire brake system of all
contaminated fluid. If the brake fluid is OK, replace
themastercylinder(seepage19-24).
6. Loosen the bleed screws at each caliper, then spin the wheels to check for brake drag.
Check the master cylinder reservoir for
contamination in the brake fluid. If you find
contamination, flush the entire brake system of all
contaminated fluid. If the brake fluid is OK,
disassemble and repair the caliper, on the wheel(s)
with brake drag.
Look for and replace any damaged brake lines.
If all brake lines are OK, replace the ABS or VSA
modulator-control unit: ABS (see page 19-90), VSA
(see page 19-171).

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.
