Fuse and Fusible Link Locations

TROUBLESHOOTING WITH VOLT/OHMMETER

NOTE:

The following troubleshooting procedures are designed for inspection of each separate system and therefore the actual procedure may vary somewhat. However, troubleshooting should be performed referring to the inspection methods described.

Before beginning inspection, it is best to first make a simple check of the fuses, fusible links and condition of the connectors.

The troubleshooting procedures described 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 it can be assumed that the ECU is faulty and should be replaced.
