Are there continuities?
YES – Replace the ECM with a known good
one, and recheck.
NO – • Open circuit in White/red wire
• Open circuit in Green/orange wire
4. Bank Angle Sensor Output Line Open Circuit
Inspection
Turn the ignition switch OFF.
Disconnect the ECM 33P connector.
Check the continuity between the ECM 33P and
bank angle sensor 3P connectors.
Is there continuity?
YES – Inspect the bank angle sensor (page 5-
64).
NO – Open circuit in Red/blue wire
