INSPECTION PROCEDURE
1 Check whether the engine can be started with the master key and sub±key for
another vehicle of the same type.
RESULT:
AAll keys start the engine.
BA specific key does not start the engine. In this case, DTC
21 or 22 is not stored in memory.
CAll keys do not start the engine. In this case, DTC 21 and 22
are not stored in memory.
A No problem at this time.
HINT:
If the result is ºAº, confirm whether or not the customer has ever
inserted the key (without a transponder chip) of another vehicle
into the ignition key cylinder.
B The transponder chip of a specific key is defec-
tive. Replace the key.
C
2 Check transponder key coil (See page BE±143).
NG Replace transponder key coil.
OK
3 Check harness and connector between transponder key ECU and transponder
key amplifier (See page IN±35).
NG Repair or replace harness or connector.
OK

39 N´m (400 kgf´cm, 29 ft´lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(c) Observe the following precautions when removing or
installing the injectors.
(1) Never reuse the O±ring.
(2) When placing a new O±ring on the injector, take
care not to damage it in any way.
(3) Coat a new O±ring with spindle oil or gasoline be-
fore installing. Never use engine, gear or brake oil.
(d) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
Before installing the injector, apply spindle oil or gasoline
on the place where the delivery pipe or the intake man-
ifold touches the O±ring of the injector.
(e) Observe the following when disconnecting the fuel tube
connector (quick type):
(1) Check if there is any dirt in the pipe and around the
connector before disconnecting the fuel tube con-
nector. If necessary, clean the dirt away.
(2) Disconnect the fuel pipe clamp from the connector.
(3) Be sure to disconnect them by hand.
(4) When the connector and the pipe are stuck, push
and pull the connector. Then disconnect and pull it
out. Do not use any tools at this time.
(5) Check if there is any dirt or other foreign matter on
the seal surface of the disconnected pipe. If neces-
sary, clean the dirt away.
(6) Do not damage the disconnected pipe and connec-
tor and prevent intrusion of foreign objects by cover-
ing them with a plastic bag.

(f) Observe the following when connecting the fuel tube con-
nector (quick type):
(1) Check if there is any damage or foreign objects in
the connected part of the pipe.
(2) Match the axis of the connector with the axis of the
pipe, and push into the connector until a ºclickº
sound is heard. If the connection is tight, apply a
small amount of fresh engine oil on the tip of the
pipe.
(3) After finishing the connection, pull the pipe and the
connector to ensure it is secure.
(4) Check to make sure no fuel leak is present.
If the result is not specified, repair or replace.
(5) Install the fuel pipe clamp to the connector.
(6) Check to make sure no fuel leak is present.
If the result is not specified, repair or replace.
(g) Observe the following when disconnecting the fuel tube
connector (metallic type):
HINT:
The structure of the metallic connector is shown on the left.
(1) Check if there is any dirt in the pipe and around the
connector before disconnecting the fuel tube con-
nector. If necessary, clean the dirt away.
(2) Assemble SST to the connecting part, as shown in
the illustration.

the SST to put the retainers on the SST chamfered
parts.
(5) Slide the SST and connector together towards the
fuel tube assembly.
(h) Observe the following when connecting the fuel tube con-
nector (metallic type):
(1) Check if there is any damage or foreign objects in
the connected part of the pipe.
(2) Match the axis of the connector with the axis of the
pipe, and push into the connector until a ºclickº
sound is heard. If the connection is tight, apply a
small amount of fresh engine oil on the tip of the
pipe.
