1. Using EST, open the D_ContinuousMonitor.ssn.
2. To monitor signal voltage, run KOEO Continuous Monitor Test.
3. Monitor BCP signal voltage. Verify an active DTC for the BCP circuit.
4. If code is active, do step 6 and 7 to check circuit for the BCP sensor using the following tables:
• Circuit Checks for BCP Sensor – ECM to Valve Cover Gasket Connector
• Circuit Checks for BCP Sensor – ECM to BCP Sensor
5. If code is inactive, wiggle connectors and wires at all suspected problem locations. If circuit continuity is interrupted, the EST will display DTCs related to the condition.
6. Disconnect engine harness from valve cover gasket connector.
NOTE: Inspect connectors for damaged pins, corrosion, or loose pins. Repair if necessary.
7. Connect VC Gasket Breakout Harness to engine harness only.
