INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering wheel free play (See page SR±9).
(b) Check the steering linkage for looseness or damage.
Check that:

Tie rod ends do not have excessive play.

Dust seals are not damaged.

Boot clamps are not loose.
2. INSPECT SRS AIRBAG (See page RS±3)
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leaks.
If leakage is found, check the cause and repair.
4. 4WD:
INSPECT DRIVE SHAFT BOOTS
Inspect the drive shaft boots for clamp looseness, grease leak-
age or damage.
5. INSPECT BALL JOINTS AND DUST COVERS
(a) Inspect the ball joints for excessive looseness.
(b) Inspect the dust cover for damage.
6. 2WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION
AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.

(b) Differential:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Differential oil: See page SA±129
7. 4WD:
CHECK OIL LEVEL IN AUTOMATIC TRANSMISSION,
TRANSFER AND DIFFERENTIAL
(a) Automatic transmission:
Check that the fluid level is in the ºHOTº range at the nor-
mal operating temperature (70 ± 80°C or 158 ± 176°F)
and add as necessary.
NOTICE:
Do not overfill.
Transmission fluid (A/T): See page DI±524
(b) Transfer:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil
until it reaches the bottom of the filler hole.
Transfer oil: See page TR±4
(c) Differential:
Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole. If the level is low, add oil

2. ACTIVE TEST
HINT:
Performing an ACTIVE TEST enables components including the relays, VSV (Vacuum Switching Valve),
and actuators, to be operated without removing any parts. The ACTIVE TEST can be performed with a
hand±held tester. Performing an ACTIVE TEST as the first step of troubleshooting is one method of shorten-
ing diagnostic time.
DATA LIST can be displayed during ACTIVE TESTs.
(a) Connect a hand±held tester to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE TEST.
(e) Perform the ACTIVE TEST by referring to the table below.
Hand±held Tester DisplaysTest DetailsControl RangesDiagnostic Notes
INJ VOLChange injection volumeBetween ±12 % and 25 %

All injectors tested at the same
time

Perform test at less than 3,000
rpm

Injection volume can be changed
in 1 % graduations within control
range
A/F CONTROLChange injection volumeLower by 12.5 % or increase by 25
%

Perform test at less than 3,000

A/F CONTROL enables checking
and graphing of A/F (Air Fuel Ra-
tio) sensor and Heated Oxygen
(HO2) sensor voltage outputs
