Negative Camber
The front suspension adopts negative camber to reduce the ground contact camber angle of the outer wheel
at the time of turning (cornering), which is caused when the vehicle posture changes during cornering, thus
realizing excellent cornering performance.
Suspension Upper Support and Dust Cover
The upper support optimizes the characteris-
tics of the rubber mount. Also, a rebound stop-
per has been provided to ensure riding com-
fort, drivability, and stability.
A bound stopper made of urethane has been
adopted. By optimizing the stopper character-
istics and the clearance, excellent riding com-
fort and a high level of roll rigidity have been
achieved.
An upper insulator that is integrated with the
dust boot has been adopted.

(c) Starting with the Tc terminal, ground alternately terminal
Tc and terminal A/B twice each in cycles of 1.0 second.
Make sure that the terminals are grounded. Ensure the
terminal Tc remain grounded.
HINT:
When alternately grounding terminals Tc and A/B, release
ground from one terminal and immediately ground the other ter-
minal within an interval of 0.2 seconds.
If DTCs are not cleared, repeat the above procedure until the
codes are cleared.
(d) Several seconds after doing the clearing procedure, the
SRS warning light will blink in a 50 ± m sec. cycle to indi-
cate the codes which have been cleared.
6. DTC CLEARANCE (Using TOYOTA hand±held tester)
(a) Hook up the TOYOTA hand±held tester to the DLC3.
(b) Clear the DTCs by following the prompts on the tester
screen.
HINT:
Please refer to the TOYOTA hand±held tester operation's
manual for further details.

9. INSPECT VALVE STEMS AND GUIDE BUSHINGS
(a) Using a caliper gauge, measure the inside diameter of the
guide bushing.
Bushing inside diameter:
5.010 ± 5.030 mm (0.19724 ± 0.19803 in.)
(b) Using a micrometer, measure the diameter of the valve
stem.
Valve stem diameter:
Intake 4.970 ± 4.985 mm (0.19567 ± 0.19626 in.)
Exhaust 4.965 ± 4.980 mm (0.19547 ± 0.19606 in.)
(c) Subtract the valve stem diameter measurement from the
guide bushing inside diameter measurement.
Standard oil clearance:
Intake 0.025 ± 0.060 mm (0.00098 ± 0.00236 in.)
Exhaust 0.030 ± 0.065 mm (0.00118 ± 0.00256 in.)
Maximum oil clearance:
Intake 0.08 mm (0.0031 in.)
Exhaust 0.10 mm (0.0039 in.)
If the clearance is greater than maximum, replace the valve and
guide bushing.
10. INSPECT VALVES
(a) Check the valve is ground to the correct valve face angle.
Valve face angle: 44.5°
(b) Check that the surface of the valve for wear.
If the valve face is worn, replace the valve.
(c) Check the valve head margin thickness.
Standard margin thickness:
1.00 ± 1.15 mm (0.0393 ± 0.0453 in.)
Minimum margin thickness: 0.7 mm (0.028 in.)
If the margin thickness is less than minimum, replace the valve.
