TROUBLESHOOTING WITH VOLT OHMMETER

HINT: Because the following troubleshooting procedures are designed for inspection of each
separate system, the actual troubleshooting procedure may vary somewhat.
However, please refer to these procedures and perform actual troubleshooting, conforming to the
inspection methods described.
For example it is better to first make a simple check of the fuses, fusible links and connecting
condition of the connectors before making your inspection according to the procedures listed.
The following troubleshooting procedures are based on the supposition that the trouble lies in
either a short or open circuit in a component outside the computer or a short circuit within the
computer. If engine trouble occurs even though proper operating voltage is detected in the
computer connector, then the ECM is faulty and should be replaced.
