NOTE: Make sure the TPMS control unit mounting
bracket is not bent or twisted as this may affect its
communication with the tire pressure sensors.
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.

1. Before installing the tire pressure sensor, clean the
mating surfaces on the sensor and the wheel.
2. Install the tire pressure sensor (A) and the washer (B) to the wheel (C), and tighten the valve stem nut
(D) finger tight. Make sure the pressure sensor is
restingonthewheel.
NOTE: Install the tire pressure sensor so that
sensor housing surface (E) should not exceed
protrusion (F) of wheel to prevent the sensor
housing from being caught on the bead of the tire
when assembling the tire.
3. Tighten the valve stem nut to the specified torque while holding the tire pressure sensor.
NOTE: Do not use air or electric impact tools to tighten a valve stem nut.
 Do not twist the tire pressure sensor to adjust its position with the wheel, as this will damage or
deform the valve stem grommet. 4. Lube the tire bead sparingly with a paste-type tire
mounting lubricant, and 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 install the tire onto the
wheel.
5. With a dry air source, inflate the tire to 300 kPa (3.1 kgf/cm , 44 psi) to seat the tire bead to the rim,
then adjust the tire pressure (see page 18-5), then
install the valve stem cap.
NOTE: Make sure the tire bead is seated on both
sides of the rim uniformly.
6. Check and adjust the wheel balance, then install the wheels on the vehicle.
7. Remove the jack stands, and lower the vehicle. Torque the wheel nuts to specification.
8. Connect the HDS, and memorize the tire pressure sensor IDs using the TPMS sensor initializer tool
(see page 18-52).

4. Push the PC card eject button (A) to eject the client’sPC card (if installed). Power is not required for this
function.
5. Remove the plastic cover (B) over the navigation DVD slot.
6. With the display open, temporarily reconnect the unit in the dash (to power it up).
7. Push the CD eject button (C), and navigation DVD eject button (D) (the button is behind the plastic
cover and works only when the unit is powered)
and remove the discs (hold the discs by their edges
to avoid fingerprints). To avoid scratches, place the
navigation DVD and the client’s CD in a jewel case
if available.
8. Re-attach the plastic lid that hides the navigation DVD slot.
9. Close the display by first returning the display to the upward position, and then pushing the entire
display straight back into the unit.
10. After installing the new navigation unit, re-insert the navigation DVD, the client’s CD, and the PC card. SRS components are located in this area. Review the
SRS component location (see page 24-11).
Also review the precautions and procedures (see page
24-13) in the SRS section before doing repairs or
service.
NOTE:
 Put on gloves to protect your hands.
 Take care not to scratch the dashboard and related parts.
 Lay a workshop towel under the parts when working on them to protect the face panel from scratches or
other damage.
 Do not work in a dusty or dirty place.
 Discharge static electricity from your body before and during the work.
 Do not touch the circuit board(s) with your bare hands.
 Do not work with dirty hands.
 Be careful not to fold the flat plate cable.
 Do not touch the terminal connector of the flat plate cable with your bare hands. (If you have touched it,
wipe it off thoroughly.)
 Before replacing the navigation unit, make sure to remove the client’s navigation DVD, and their audio
CD, or PC card. Remanufactured navigation units do
not come with a navigation DVD. Re-install the client’s
navigation DVD, audio CD, and audio PC card into the
new remanufactured unit. If the navigation display
won’t open, manually remove the navigation DVD,
audio CD, and PC card (see page 23-354).
 If you are replacing the navigation unit, write down the audio presets (if possible), then enter them into
the new navigation unit.
1. Make sure you have the 4-digit anti-theft code for the navigation system.
2. Eject the DVD from the original navigation unit. To avoid scratching or damaging the DVD, temporarily
place the DVD in jewel case.
3. Remove the subdisplay visor (see page 20-100).
