DRIVE BELT (1CD–FTV)
ON–VEHICLE INSPECTION
1. INSPECT DRIVE BELT INSTALLATION CONDITION
Check that the drive belt fits properily in the ribbed grooves.
2. INSPECT DRIVE BELT DEFLECTION
Using a belt tension gauge, apply load of 98 N (10 kgf, 22 lbf)
and measure drive belt deflection.
Drive belt deflection:
New belt: 11 – 13 mm (0.47 – 0.51 in.)
Used belt: 15 – 18 mm (0.59 – 0.71 in.)
HINT:

”New belt” refers to a belt which has been used less than
5 minutes on the running engine.

”Used belt” refer to a belt which has been on a running en-
gine for 5 minutes or more.

After installing the drive belt, check that it fits properly in
the ribbed grooves.
3. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Drive belt tension:
New belt: 520 – 755 N (53 – 77 kgf)
Used belt: 196 – 392 N (20 – 40 kgf)

ON–VEHICLE INSPECTION
NOTICE:

If the glow plug breaks, the ECU detects the breakage and stops the automatic operation, so
the burner heater does not activate. (For other failures, similarly activated.)

The cause of failures (such as voltage malfunction, overheating malfunction, short–circuit or
breakage of functional componects, etc.) and how to remedy are shown by connecting the DTC
tester and reading the DTC.
1. OPERATION
(a) Connect the DTC tester between the connector A (Vehicle harness) of DTC check harness and con-
nector B (Power heater harness).
(b) Start the engine.
(c) Pressing the DTC calling button displays a 3–digit number DTC.
