CIRCUIT INSPECTION
INSPECTION AT ECM CONNECTOR
• Always clean around and keep any foreign material away from the
PCM/ECM connector before disconnecting it.
• A faulty PGM-FI system is often related to poorly connected or cor-
roded connections. Check those connections before proceeding.
• In testing at PCM/ECM connector (wire side) terminal, always use
the test probe. Insert the test probe into the connector terminal,
then attach the digital multimeter probe to the test probe.
