C5: Check Ground Continuity

With connectors FC025, FC024 and BT015 disconnected measure the resistance between FC025/014 and BT015.

- Is the resistance < 0.5 ohms?
Yes
GO to C6 C6: Check Signal Continuity
No
Inspect harness/connectors/pins FC025, FC001/007, BT004/026 and BT015 for corrosion, damage, bent or pushed back pins. Repair as required and test the system for normal operation.
