EFI SYSTEM — Troubleshooting with Volt/Ohmmeter

TROUBLESHOOTING WITH
VOLT/OHMMETER
HINT: The following troubleshooting proce-
dures are designed for inspection of each sepa-
rate system, and therefore the actual procedure
may vary somewhat. However, troubleshooting
should be performed referring to the inspection
methods described in this manual.
Before beginning inspection, it is best to first
make a simple check of the fuses, fusible links and
condition of the connectors.
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.
If engine trouble occurs even though proper op-
erating voltage is detected in the computer con-
nector, then it can be assumed that the ECU is
faulty and should be replaced.
