NOTICE:

Check the drive belt deflection at the specified point.

When installing a new belt, set its tension value as
specified.

When inspecting the belt which is used over 5 min-
utes, apply the specifications of ºUsed Belt.º

When reinstalling the belt which is used over 5 min-
utes, adjust its deflection and tension to the medium
value in each specification of ºUsed Belt.º

V±ribbed belt tension and deflection should be
checked after 2 revolutions of engine cranking.

When using a belt tension gauge, confirm the accura-
cy by using a master gauge first.
(b) Inspect generator V belt. (1) Check that the tension indicator is within range A onthe auto tensioner scale.
If the tension is not within the A range, replace the belt with a
new one.
HINT:
When replacing the drive belt with a new one, the belt tension
should be within the B range.

DIAGNOSTICS ECD SYSTEM (1CD−FTV)(From September, 2003)
AVENSIS Supplement (RM1045E)
DTC P0622 GENERATOR FIELD ”F” TERMINAL CIRCUIT
CIRCUIT DESCRIPTION
While the generator (alternator) is generating current, a duty ratio is sent from terminal M of the generator
to the ECM terminal ALT. This duty ratio is used for detecting an open malfunction of the generator circuit
and DTC P0380.
HINT:
DTC P0380 is prepared for indicating an open or short malfunction in the glow plug circuit. If this DTC is de-
tected, inspect the glow plug circuit. (See page 05 −386)
DTC No.DTC Detection ConditionTrouble Area
P0622
No duty ratio from terminal M of the generator (alternator) at
the engine running

S Drive belt
S ECM
HINT:
After confirming DTC P0622, check the internal fuel pressure of the common rail in the ”DIAGNOSIS / OBD/
MOBD / DATA LIST / ALL / GENERATOR” using the hand −held tester.
Result:

Idling10 to 100
When increasing engine speedGenerator duty ratio drops
When decreasing engine speedGenerator duty ratio rises
MONITOR DESCRIPTION
The ECM will detect a generator (alternator) failure or an open malfunction of the circuit, if the duty ratio is
not output from terminal M of the generator (alternator) despite running the engine.
