D4: Check Harness Continuity (Sensor Supply 5 Volts)

Ensure EM011, FP001 and EM010 are disconnected.
Measure resistance between EM011/008 and FP001/003.

- Is the resistance < 0.5 ohms?
Yes
GO to D5 D5: Check Harness Isolation
No
Inspect harness/connectors EM011, FP001, EM003, FC001, BT004 and BT005 for damage, corrosion, bent/pushed back pins. Repair as necessary and test the system for normal operation.
