4. Using the preload gauge, measure the preload torque of the pin-
ion bearing.
CAUTION:
Every rotational part shall rotate smoothly with the speci-
fied gear oil.

If measured value is out of the specification, disassemble the
pinion sleeve assembly to check and adjust each part.
Total Preload Torque
1. Measure pinion bearing preload torque (P1 ). Refer to TF-62, "Pinion Bearing Preload Torque" .
2. Install the pinion sleeve shims and pinion sleeve assembly.
3. Rotate the companion flange at least 20 times to check for smooth operation of the bearing.
4. Using the preload gauge, measure the total preload torque.

If measured value is out of the specification, disassemble it to
check and adjust each part. If measuring the total preload
torque after the disassembly, measure it with the transfer case oil seals and gear ring oil seals
removed, then install the oil seals.
Companion Flange Runout
1. Fit a dial indicator onto the companion flange face (inner side of
the propeller shaft mounting bolt holes).
2. Rotate the companion flange to check for runout.
3. Fit a test indicator to the inner side of the companion flange
(socket diameter).
4. Rotate the companion flange to check for runout.
5. If the runout value is outside the repair limit, follow the procedure
below to adjust.
a. While changing the phase between companion flange and drive pinion gear by 90° at a time, check runout
and determine which phase angle minimizes the runout.
b. If the runout value is still outside of the limit after the phase has been changed, replace the companion
flange.
c. If the runout is out of the specification after replacement of companion flange, adjust the assembly status
of the pinion bearings and drive pinion gear, or replace the pinion bearings.Tool number : ST3127S000

FUNCTION INSPECTION
With engine stopped, discharge stored vacuum by depressing brake
pedal several times at 5 second intervals. With brake pedal fully
depressed, start the engine. Confirm that clearance between brake
pedal and floor panel decreases when engine vacuum stabilizes.
AIRTIGHTNESS INSPECTION

Run engine at idle for approximately 1 minute. Stop it after
applying vacuum to the booster. Depress brake pedal several
times with normal force to discharge the stored vacuum. Con-
firm that clearance between brake pedal and floor panel gradu-
ally increases as the brake pedal is depressed.

Run engine. Depress and hold brake pedal then stop engine.
Keep brake pedal depressed for 30 seconds or more and make
sure the pedal stroke does not change.

TROUBLE DIAGNOSIS

For Fast and Accurate DiagnosisEFS005W4
PRECAUTIONS FOR DIAGNOSIS

Before performing diagnosis, always read precautions. Refer to BRC-60, "How to Proceed With Diagno-
sis" .

If ESP/TCS/ABS control unit steering angle sensor, steering system parts or suspension system parts
have been replaced, or if alignment has been adjusted, be sure to adjust neutral position of steering angle
sensor before driving. Refer to BRC-52, "
Adjustment of Steering Angle Sensor Neutral Position" .

After diagnosis is finished, be sure to erase memory. Refer to BRC-81, "SELF-DIAGNOSIS" .

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

To use CONSULT-II to perform self-diagnosis of ESP/TCS/ABS control unit active tests, or work support,
first stop work, then connect CONSULT-II and select “ABS”.

While self-diagnostic results of CONSULT-II shows malfunction, if CONSULT-II active test is performed,
an engine system malfunction may be indicated. In this case, start engine to resume the normal screen.

ESP/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:
ON and OFF Timing for ABS Warning Lamp, ESP OFF Indicator Lamp, SLIP Indicator Lamp,
Brake Warning Lamp
×: ON –: OFF Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ESP/TCS/ABS control unit. Slight noise
may occur during ESP, TCS, and ABS operation.
Normal
When the vehicle speed goes over 20 km/h (12.5 MPH), motor and
valves operating noise may be heard. It happens only once after ignition
switch is ON. This is a normal status of the system operation check.
System operation check
noiseWhen engine starts, slight “click” noise may be heard from engine room.
This is normal and is part of system operation check.Normal
ESP/TCS operation
(SLIP indicator lamp blink-
ing)TCS may activate momentarily if wheel speed changes when driving
over location where friction coefficient varies, when downshifting, or
when fully depressing accelerator pedal.Normal
Cancel the ESP/TCS
function for the
inspection on a chas-
sis dynamometer. When checking speed meter etc. with a 2-wheel-drive chassis dyna-
mometer, vehicle speed is not increased by pressing down on the accel-
erator.
ABS operation (Longer stop-
ping distance)On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.Normal
Insufficient feeling of accel-
erationDepending on road conditions, driver may feel that feeling of accelera-
tion is insufficient. This is because traction control, which controls
engine and brakes to achieve optimal traction, has the highest priority
(for safety). As a result, there may be times when acceleration is slightly
less than usual for the same accelerator pedal operation.Normal
