CPU (Central Processing Unit) of ECM
ECM and malfunction indicator lamp (1) operate as follows.
D
Malfunction indicator lamp (1) lights when the ignition switch is
turned ON (but the engine at stop) with the diagnosis switch ter-
minal ungrounded regardless of the condition of Engine and
Emission Control system. This is only to check the malfunction
indicator lamp (1) bulb and its circuit.
D
If the above areas of Engine and Emission Control system is free
from any trouble after the engine start (while engine is running),
malfunction indicator lamp (1) turns OFF.
D
When ECM detects a trouble which has occurred in the above
areas, it makes malfunction indicator lamp (1) turn ON while the
engine is running to warn the driver of such occurrence of trouble
and at the same time it stores the trouble area in ECM back-up
memory. (The memory is kept as it is even if the trouble was only
temporary and disappeared immediately. And it is not erased un-
less the power to ECM is shut off for specified time below.)
ECM also indicates trouble area in memory by means of flashing
of malfunction indicator lamp (1) at the time of inspection. (i.e.
when connecting diagnosis switch terminal (2) and ground termi-
nal (4) of monitor connector (3) with a service wire (5) and ignition
switch is turned ON.)
NOTE:
D
When a trouble occurs in the above areas and disappears
soon while the diagnosis switch terminal is ungrounded
and the engine is running, malfunction indicator lamp (1)
lights and remains ON as long as the trouble exists but it
turns OFF when the normal condition is restored.
D
Time required to erase diagnostic trouble code memory
thoroughly varies depending on ambient temperature as
follows.
