SELF-DIAGNOSTIC PROCEDURES

* Don't disconnect couplers from ECM, the battery cable from
the battery, ECM ground wire harness from the engine or main
fuse before confirming the malfunction code (self-diagnostic
trouble code) stored in the memory. Such disconnection will
erase the memorized information in ECM memory.
* Malfunction code stored in ECM memory can be checked by
the special tool.
* Before checking malfunction code, read SELF-DIAGNOSIS
FUNCTION "USER MODE and DEALER MODE" ($14-30
and -31) carefully to have good understanding as to what func-
tions are available and how to use it.
* Be sure to read "PRECAUTIONS for Electrical Circuit Service"
($14-18) before inspection and observe what is written
there.
• Remove the right frame cover. ($7-2)
• Connect the special tool to the dealer mode coupler A at the
wiring harness, and start the engine or crank the engine for
more than 4 seconds.
• Turn the special tool's switch ON and check the malfunction
code to determine the malfunction part.
