FUEL SYSTEM
INSPECTION AT ECM CONNECTOR
• Always clean around and keep any foreign material
away from the ECM connector before disconnecting
it.
• A faulty PGM-FI system is often related to poorly
connected or corroded terminals. Check those
connections before proceeding.
• In testing at the ECM connector (wire harness side)
terminal, always use the test probe. Insert the test
probe into the connector terminal, and then attach
the digital multimeter probe to the test probe.
TOOL:
Test probe (1)
FINAL PROCEDURE (AFTER

shown on page 5-6.

check connector is connected to the DLC.
