11.REMOVE NOZZLE HOLDER SEAL
(a)Using a screwdriver, pry out the 4 nozzle holder seals.
12.REMOVE CYLINDER HEAD COVER SUB±ASSY
(a)Remove the 10 bolts and the cylinder head cover.
13.REMOVE NOZZLE LEAKAGE PIPE ASSY
(a)Remove the union bolt and the 4 hollow screws, then re-
move the nozzle leakage pipe and the 5 gaskets.
NOTICE:
When removing then nozzle leakage pipe, place the shop
rag under the pipe to protect the cylinder head from the fuel
remaining inside the pipe.
14.REMOVE NOZZLE HOLDER CLAMP
(a)Remove the 4 bolts, 4 washers and 4 nozzle holder clamps.
15.REMOVE INJECTOR ASSY
(a)Remove the 4 injectors from the cylinder head.
(b)Remove the O±rings and back±up rings from each injector.
(c)Remove the 4 nozzle seats from the cylinder head.
16.REGISTRATION OF INJECTOR COMPENSATION CODE (See page 05±528)
HINT:
Each injector assembly has a characteristic fuel injecting behavior. When replacing the injector assembly,
store them in correct order so that they can be returned to the original\
locations when re±assembling. 17. INSTALL INJECTOR ASSY
(a) Install 4 new nozzle seats to the cylinder head.

REGISTRATION
1. REGISTER RECOGNITION CODE
HINT:
Register the recognition code when replacing the door control transmitter or the door control receiverr.
The add mode is used to register new recognition codes while still retaining codes already registered.
This mode is used when a new transmitter is added. If the number of registered codes exceeds 4, the
previously registered codes will be erased in order, starting from the first registered code.
The rewrite mode is used to erase all the previously registered recognition codes in order to register
new recognition codes. This mode is used when the transmitter or the door control receiver is ex-
changed for a new one.
The confirmation mode is used to confirm how many recognition codes have already been registered
before an additional registration of a recognition codes.
The all clear mode is used to erase all the registered codes and disables the wireless door lock func-
tion. This mode is used when the transmitter is lost.
All the following registration procedures must be performed in order continuously.
