Warning
•Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
•Fuel line spills and leads are dangerous. Fuel can ignite and cause serious injuries or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the following “Fuel
Line Safety Procedures”.
Fuel Line Safety Procedures
Note
•Fuel in the fuel system is under high pressure when the engine is not running.
1. Avoid fuel line spills and leaks by completing the following procedures.
(1) Remove the fuel-filler cap and release the pressure in the fuel tank.
(2) When disconnecting a fuel line hose, wrap a rag around it to protect against fuel leakage.
(3) Plug the hose after removal.

AFTER REPAIR PROCEDUREA6E401201006204
Warning
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injuries or death and
damage. When installing the fuel hose, observe “Fuel Hose Installation” described below.
Fuel Line Air Bleeding
Caution
•Continuously cranking the engine for over 30 s can damage the battery and the starter.
1. Continue cranking the engine for 30 s and stop for 5—10 s until the engine starts.
Fuel Hose Installation

FUEL TANK REMOVAL/INSTALLATIONA6E401242110201
Warning
•Repairing a fuel tank that has not been properly steam cleaned can be dangerous. Explosion or
fire may cause death or serious injury. Always properly steam clean a fuel tank before repairing it.
•Fuel line spills and leakage are dangerous. Fuel can also irritate skin and eyes. To prevent this, do
not damage the sealing surface of the fuel gauge sender unit when removing or installing.
Caution
•Disconnecting/connecting the quick release connector without cleaning it may possibly cause
damage to the fuel pipe and quick release connector. Always clean the quick release connector
joint area before disconnecting/connecting using a cloth or soft brush, and make sure that it is
free of foreign material.

Plastic Fuel Hose Removal Note
Caution
•The quick release connector may be damaged if the tab is bent excessively. Do not expand the tab
over the stopper.
1. Disconnect the quick release connector.
(1) Push the tab on the locking coupler 90 degrees until it stops.
(2) Pull the fuel hose straight back.
Note
•The stopper may be removed from the quick
connector. Take care not to lose it.
Reinstall it to the quick release connector
before reconnecting the fuel line.
•The locking coupler has two internal locking
tabs which retain the fuel pipe. Be sure that
the tab on the locking coupler is rotated until
it stops to release two internal locking tabs.
2. Cover the disconnected quick release connector
and fuel pipe with vinyl sheets or the like to
prevent them from being scratched or
contaminated with foreign material.
Fuel Tank Gauge Cap Removal Note
1. Using the SST, remove the fuel tank gauge cap.

TORQUE CONVERTER DESCRIPTIONA6E571419100201Outline
•The JA5AX-EL uses a three-element, single-gear, two-phase torque converter with torque converter clutch
(TCC) mechanism.
•The torque converter efficiently matches the output characteristic of AJ engine.
•By matching the output characteristics of the engine in order to optimize the configuration of the impellers, the
torque converter increases the capacity coefficient in the practical range, thereby improving drivability and fuel
economy.
•The TCC mechanism under certain conditions transmits the drive force by automatically connecting the pump
impeller with the turbine runner as opposed to using fluid. Therefore it prevents the torque converter from
slipping.
