Does continuity go away when one of the above components is disconnected?
YES - Replace the component that made the short to body ground go away when disconnected. If the item is the ECM/PCM, update the
ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/PCM.
Also replace the No.8 FI ECU (ECM/PCM) (15 A) fuse.
NO - Go to step 29.
29. Disconnect the connectors from these components.
