1. Disconnect following components or connectors, one at a time, and check for continuity between PGM-FI main relay 1 (FI MAIN) 4P connector terminal No. 1 and body ground.
   - PGM-FI main relay 2 (FUEL PUMP)
   - A/F sensor relay
   - Throttle actuator control module relay
   - ECM/PCM connector A (31P)
   - Each injector 2P connector
   - Idle air control (IAC) valve 3P connector
   - Camshaft position (CMP) sensor B 3P connector
   - Crankshaft position (CKP) sensor 3P connector

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 .

1. Disconnect the connectors of all these components.
