CH–62AZ-FE CHARGING – CHARGING SYSTEM
CH
8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high
beam headlights ON and turn the heater blower
switch to the "HI" position.
(b) Check the reading on the ammeter.
Standard amperage:
30 A or more
If the ammeter reading is less than the standard
amperage, repair the generator.
HINT:
If the battery is fully charged, the indication will
sometimes be less than the standard amperage. If
this is the case, add more electrical load (operate
the wipers, rear window defogger, etc.) and check
the reading on the ammeter again.

(f) Remove the 16 bolts and the transaxle housing.
(g) Remove the differential assembly.
7. INSTALL FRONT DIFFERENTIAL RING GEAR
(a) Using ATF and a heater, heat the front differential
ring gear to 90 to 110
C (194.0 to 230.0F).
NOTICE:
Do not overheat the ring gear to 110
C (230.0F)
or more.
(b) Clean the contract surface of the front differential
case.
(c) Align the matchmarks, and install the front
differential ring gear case quickly.
NOTICE:
• Check the position and number of the
grooves on each end face of the differential
ring gear.
• Do not install the bolts while the ring gear is
hot.
(d) Tighten the 14 bolts.
Torque: 95 N*m (969 kgf*cm, 70 ft.*lbf)
NOTICE:
Tighten the bolts a little at a time in diagonal
order.

SEAT BELT – SEAT BELT WARNING SYSTEMSB–3
SB
SYSTEM DESCRIPTION
1. DRIVER SEAT BELT WARNING LIGHT
(a) When the driver seat belt is not fastened with the
ignition switch ON, the driver seat belt warning light
on the combination meter comes on to inform the
driver. The center airbag sensor detects the driver
seat belt status and sends signals to the
combination meter through the CAN bus line.
2. PASSENGER SEAT BELT WARNING LIGHT
(a) for Automatic air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the heater control panel display
blinks. The combination meter detects the
passenger seat belt status and whether the
passenger seat is occupied.
(b) for Manual air conditioning system:
When the passenger seat belt is not fastened with
the ignition switch ON and the passenger seat
occupied, check that the passenger seat belt
warning light on the clock panel blinks. The
combination meter detects the passenger seat belt
status and whether the passenger seat is occupied.

– Air-fuel ratio feedback control is performed.
(b) Drive Pattern for front A/F sensor and HO2 sensor
(1) Connect the intelligent tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Turn the tester ON.
(4) Clear DTCs (see page ES-35).
(5) Start the engine, and warm it up until the ECT
reaches 75
C (167F) or higher.
(6) Drive the vehicle at between 60 km/h (38 mph)
and 120 km/h (75 mph) for at least 10 minutes.
(7) Change the transmission to 2nd gear.
(8) Accelerate the vehicle to 64 km/h (40 mph) or
more by depressing the accelerator pedal for at
least 10 seconds.
(9) Soon after performing step (8) above, release
the accelerator pedal for at least 4 seconds without
depressing the brake pedal, in order to execute fuel-
cut control.
(10) Allow the vehicle to decelerate until the vehicle
speed declines to less than 10 km/h (6 mph).
(11) Repeat steps from (8) through (10) above at
least 3 times in one driving cycle.
(c) Monitor Status
(1) Check the Readiness Monitor status displayed
on the tester.
(2) If the status does not switch to COMPL
(complete), make sure that the preconditions
have been met, and then perform steps from (5)
through (11) in the Drive Pattern above.
