NOTICE:
Check the drive belt deflection at the specified point.
When installing a new belt, set its tension value as
specified.
When inspecting a belt which is used for over 5 min-
utes, apply the specification of ºUsed beltº.
When reinstalling a belt which is used for over 5 min-
utes, adjust its belt deflection and tension to the inter-
mediate value of each specification in ºUsed beltº.
The V- ribbed belt tension and deflection value
should be checked after 2 revolutions of engine
cranking.
When using a belt tension gauge, confirm the accura-
cy first by using a master gauge.
7. INSPECT IGNITION TIMING
(a) Warm up engine.
(b) When using the hand-held tester or OBD II scan tool:
(1) Connect the hand-held tester or OBD II scan tool
to the DLC3.
(2) Enter DATA LIST MODE on the hand-held tester or
OBD II scan tool.
Ignition timing: 8 to 12 BTDC
HINT:
Refer to the hand-held tester or OBD II scan tool operator's
manual if you need help to select DATA LIST.
