D3: Check Harness Continuity (Sensor Supply Ground)

Ensure EM011, FP001 and EM010 are disconnected.
Measure resistance between EM010/020 and FP001/001. EM011/012 and FP001/001.

- Is the resistance < 0.5 ohms?
Yes
GO to D4 D4: Check Harness Continuity (Sensor Supply 5 Volts)
No
Inspect harness/connectors EM011, FP001, EM003, FC001, BT004, BT005, splices EMS1 and EMS2 for damage, corrosion, bent/pushed back pins. Repair as necessary and test the system for normal operation.
