Page 2 of 4
There are two types of brake calipers: floating and fixed. Check the type of brake caliper
installed on the vehicle by removing the wheel assembly.
1. Floating Type Brake Caliper
A. Lift up or remove the brake caliper
and suspend it securely.
HINT:
Do not disconnect the flexible hose
from the brake caliper.
B. If equipped with anti±squeal
spring: Remove the anti±squeal
springs.
C. Remove the brake pads with
anti±squeal shims.
D. Remove the pad support plates
from the torque plate. Clean any
dust from the pad support plates,
torque plates and brake pads.
E. Apply a small amount of the
disc brake caliper grease
(1±2 mm thick) to both sides
of the pad support plates.
NOTE:
Do NOT apply grease to the friction
surfaces of the brake pads or the
disc rotor.
F. If the pad support plate is fixed to
the torque plate with adhesive tape,
perform the operation according to
the following flow chart.
Without removing the pad
support plate, apply a small
amount of grease to the portion
where the pad touches the
surface of the support plate.Fixed firmly in placeThere is adhesive tape, but
it is not fixed firmly in placeAdhesive tape is peeled offRemove the pad support plate,
peel off the adhesive tape and
apply a small amount of grease to
both sides of the support plate.Remove the pad support plate
and apply a small amount of
grease to both sides of the
support plate.
Check whether or not the pad support plate
and the torque plate are fixed firmly in place
with adhesive tape.

TSB REVISION NOTICE:
The information updated in this TSB is red
and underlined.
The On±Board Diagnostic (OBDII) system is designed to monitor the performance of
emission±related components and report any detected abnormalities in the form of
Diagnostic Trouble Codes (DTCs). Since the various components need to be monitored
during different driving conditions, the OBDII system is designed to run separate
monitoring programs called Readiness Monitors. Many state Inspection and
Maintenance (I/M) programs require that vehicles complete their Readiness Monitors
prior to beginning an emissions test.
The current status of the Readiness Monitors can be seen by using the Toyota Diagnostic
Tester with version 9.0 software (or newer), or a generic OBDII Scantool.
To view the Readiness Monitor status using the Toyota Diagnostic Tester, select ªMonitor
Statusº from the Enhanced OBDII Menu.
A status of ªcompleteº indicates that the necessary conditions have been met to run the
performance tests for the related Readiness Monitor.
The Readiness Monitor will be reset to ªincompleteº if:

ECU has lost power (battery or fuse).

DTCs have been cleared.

The conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows ªincomplete,º follow the appropriate
Readiness Monitor Drive Pattern to change the readiness status to ªcomplete.º
Refer to the Readiness Monitor Drive Pattern Application Table to determine which
drive pattern should be followed.

READINESS MONITOR DRIVE PATTERNS ± EG003-02 RevisedMarch 29, 2002
Page 17 of 23
Drive Pattern Preconditions
The monitor will not run unless:

MIL is OFF.

Fuel level is between 1/2 to 3/4 full (for faster completion)
.

Altitude is 7800 feet (2400 m) or less.*

ECT (Coolant Temp) is between 40F and 95F (4.4C ± 35C).

IAT (Intake Air) is between 40F and 95F (4.4C ± 35C).*

Cold Soak Procedure has been completed.
* For 2002 MY and later vehicles: The readiness test can be completed in cold ambient conditions
(less than 40F / 4.4C) and/or at high altitudes (more than 7800 feet / 2400 m) if the complete drive
pattern (including Cold Soak) is repeated a second time after cycling the ignition OFF.
NOTE:
Before starting the engine, the difference between ECT (Coolant Temp) and IAT (Intake
Air) must be less than 13F (7C). (Refer to Examples 1 and 2 on previous page.)
Drive Pattern Procedure

Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.

Release the pressure in the fuel tank by removing and then reinstalling the fuel tank
cap.
2a. Start the engine and allow it to idle until ECT (Coolant Temp) is 167F (75C) or
greater. (See illustration on previous page.)
2b. Race the engine at 3,000 rpm for approximately 10 seconds. (See illustration on
previous page.)
2c. Allow the engine to idle with the A/C ON (to create a slight load) for 15 ± 50
minutes. (See illustration on previous page.)
NOTE:
If the vehicle is not equipped with A/C put a slight load on the engine by doing the
following:

Securely set the parking brake.

Block the drive wheels with wheel chocks.

Allow the vehicle to idle in drive for 15 ± 50 minutes.
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).

Pending Codes are available from the DTC Info Menu in Enhanced OBDII.

Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.

Once a second trip is completed, a current DTC will be stored. Readiness

PROGRAMMING OEM WIRELESS DOOR LOCK REMOTE TRANSMITTERS ± EL008±98 December 4, 1998
Page 2 of 2
The PRG (Program) circuit of the
Wireless Door Lock ECU is grounded to
perform programming. This can be
accomplished at a satellite location, the
Mirror Control Switch (see illustration).
NOTE:
Up to two remotes can be programmed
to operate each vehicle.
1. With the key OUT of the ignition
switch, locate and disconnect the
Mirror Control Switch from the vehicle
harness.
2. Using a suitable jumper wire, connect
terminal number 2, PRG (violet wire)
to terminal number 10, GND
(white/black) of the 10 cavity mirror
control switch connector (illustrated).
The vehicle confirms programming
mode by requesting the power door
locks to lock.
3. Depress, then release, any button on
the remote. The vehicle confirms
registration by requesting the power
door locks to lock once again.
4. To program an additional remote,
repeat step 3.
5. Disconnect the jumper wire to exit
programming mode.
