WITH
VOLT/OHMMETER
(MA)
OTE:
The
following
troubleshooting
pro-
sdures are designed
for inspection
of each separ-
te system,
and therefore
the actual
procedure
lay vary somewhat.
However,
troubleshooting
hould
be performed
refering
to the inspection
lethods
described
in this manual.
The
following
troubleshooting
procedures
are
based on the supposition
that the trouble
lies in
either a short or open circuit in a component
out-
side the computer
or a short
circuit
within
the
computer.
Jefore beginning
inspection,
it is best to first make
3 simple check of the fuses, fusible
links and the
:ondition
of the connectors.
If engine
trouble
occurs
even
though
proper
operating
voltage is detected
in the computer
con-
nectar,
then
it can be assumed
that the ECU is
faulty and should
be replaced.
