SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are Emergency Locking Retr actors (ELR) type. In an emergency (sudden stop) the
retractor will lock and prevent the webbing from extendi ng any further. All 3-point type seat belt retractors
except the driver seat belt also have an Automati c Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the webbing is then retracted part ially, the ALR mode automatically locks the seat belt
in a specific position so the webbing cannot be extended any further. To cancel the ALR mode, allow the seat
belt to fully wind back into the retractor.
Check the seat belt retractors with the following test(s ) to determine if a retractor assembly is operating prop-
erly.
ELR Function Stationary Check
Grasp the shoulder webbing and pull forward quickly. T he retractor should lock and prevent the belt from
extending further.
ALR Function Stationary Check
1. Pull out the entire length of seat belt from retractor until a click is heard.
2. Retract the webbing partially. A clicking noise shoul d be heard as the webbing retracts, indicating that the
retractor is in the Automatic Locking Retractors (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The webbing must lock and not extend any further. If it
does not operate normally, replace the retractor assembly.
4. Allow the entire length of the webbing to re tract to cancel the automatic locking mode.
ELR Function Moving Check
WARNING:
Perform the following test in a saf e, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be p aved and dry. Never perform the following test on
wet or gravel roads or on public streets and highw ays. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event that the
retractor does not lock.
1. Fasten driver seat belt. Buckle a passenger in to the seat for the belt that is to be tested.
2. Proceed to the designated safe area.
3. Drive the vehicle at approximately 16 km/h ( 10 MPH). Notify any passengers of a pending sudden stop
and the driver and passenger must be prepared to brace themselves in the event that the retractor does
not lock. Apply brakes firmly and make a very hard stop.
During stopping, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock,
perform the retractor off-vehicle check.
SEAT BELT RETRACTOR O FF-VEHICLE CHECK (PILLAR)
1. Remove the seat belt retractor.
• Remove the front seat belt assembly, refer to SB-8, "Removal and Installation"
.
2. Slowly pull out webbing while tilting the retracto r assembly forward from the mounted position without
twisting the retractor assembly as shown in the illustration.
A : The webbing can be pulled out in case the retractor is tilted
15 ° degree or less.
B : The webbing can not be pulled out if the retractor is tilted 35 °
degrees or more.
• A and B show tilting angles.
: Front
Replace the seat belt assembly if it does not operate within specifications.

TORQUE CONVERTER (WITH LOCK-UP FUNCTION)
In the same way as a conventional A/T, the torque c onverter is a system that increases the engine torque and
transmits the torque to the transaxle. A symmetr ical 3-element, 1-stage, 2-phase type is used here.
OIL PUMP
Utilizes a vane-type oil pump that is driven by the engi ne through the oil pump drive chain in order to increase
efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume in high-speed
zone. Discharged oil from oil pump is transmitted to contro l valve. It is used as the oil of primary and second-
ary pulley operation, the oil of clutch operation, and the lubricant for each part.
PLANETARY GEAR
• A planetary gear type of forward/reverse selector me chanism is installed between the torque converter and
primary pulley.
• The power from the torque converter is input via the i nput shaft, operating a wet multi-plate clutch by means
of hydraulic pressure to switch between forward and reverse driving.
Operation of Planetary gear
BELT & PULLEY
It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt
(the steel plates are placed conti nuously and the belt is guided with the multilayer steel rings on both sides).

Part name Function
Torque converter Increases engine torque and transmits it to the transaxle.
Oil pump Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to
increase efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume
in high-speed zone. Discharged oil from oil pump is tr ansmitted to control valve. It is used as the oil of
primary and secondary pulley operation, the oil of clutch operation, and the lubricant for each part.
Forward clutch The forward clutch is wet and multiple plate type clutch that consists of clutch drum, piston, drive plate,
and driven plate. It is a clutch to move the vehicle forward by activating piston hydraulically, engaging
plates, and directly connecting sun gear and input shaft.
Reverse brake The reverse brake is a wet multiple-plate type brake that consists of transaxle case, piston, drive plate,
and driven plate. It is a brake to move the vehicle in reverse by activating piston hydraulically, engaging
plates, and fixing planetary gear.
Internal gear The internal gear is directly connected to forward clutch drum. It is a gear that moves the outer edge of
pinion planet of planet carrier. It transmits power to move the vehicle in reverse when the planet carrier
is fixed.
Planet carrier Composed of a carrier, pinion planet, and pinion shaft. This gear fixes and releases the planet carrier in
order to switch between forward and reverse driving.
Sun gear Sun gear is a set part with planet carrier and internal gear. It transmits transmitted force to primary fixed
sheave. It rotates in forward or reverse direction according to activation of either forward clutch or re-
verse brake.
Input shaft The input shaft is directly connected to forward clutch drum and transmits traction force from torque con-
verter. In shaft center, there are holes for hydraulic distribution to primary pulley and hydraulic distribution
for lockup ON/OFF.
Primary pulley It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the steel belt. The groove width changes according to wrapping radius of steel belt and pulley from low status to
overdrive status continuously with non-step. It is controlled with the oil pressures of primary pulley and
secondary pulley.
Secondary pulley
Steel belt
Manual shaft When the manual shaft is in the P position, the parking rod that is linked to the manual shaft rotates the
parking pole. When the parking pole rotates, it engages with the parking gear, fixing the parking gear. As
a result, the secondary pulley that is integrated with the parking gear is fixed.
Parking rod
Parking pawl

Output gear
The deceleration gears are composed of 2 stages: primary deceleration (output gear, idler gear pair) and
secondary deceleration (reduction gear, final gear pair). All of these gears are helical gears.

Perform the following work after the transaxle assembly is replaced.
ERASING AND WRITING TCM DATA• TCM performs accurate control by retrieving data (inher ent characteristic value) of each solenoid. For this
reason, after replacing transaxle assembly, it is nec essary to erase data stored in TCM and write new data.
ERASING OF CVT FLUID DEGRADATION LEVEL DATA • TCM records the degradation level of the CVT fluid calc ulated from the vehicle driving status. Therefore, if
the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by
TCM.
