SELF-DIAGNOSIS
The engine control unit monitors the inputloutput
signals (some signals at all times and the others
under specified conditions) of the engine control
unitWhen it is noticed that an irregularity has
continued for a specified time or longer from when
the irregular signal is initially monitored, passing
certain number;theengine control unit judges that
an
irregularity has occurred, memorizes the
malfunction code, and outputs the signal tothe
self-diagnosis output terminals_There are18
diagnosis items, including the normal state , and the
diagnosis results can be read out witha voltmeter
or MUT-II Moreover;since memorization of the
malfunction codes is backed up directly by the
battery; the diagnosis results are memorized even
if the ignition key is turned off.The malfunction
codes will,however;be erased when the battery
terminal or the engine control unit connector is
disconnected.
The malfunction codes are also erased by setting
the ignition switch to the "ON" position and then
sending the malfunction-code-erase signal from the
MUT-II to the engine control unit:
Caution
# the sensor connector is disconnected while
the ignition switch is ON, the malfunction code
is memorized: In this instance, either send the
malfunction-code-erase signal from the MUT-II
to the engine control unit, or disconnect the
battery's negative (~) terminal for ten seconds
or longer; the diagnosis memory will be erased:
The 18 diagnosis items are provided as follows
and if plural items are activated, they are all
indicated sequentially from the smallest code
