F4: Check Harness Signal Continuity

Measure the resistance between EM013/020 and PI015/001

- Is the resistance < 0.5 ohms?
Yes
GO to F5 F5: Check Harness Short to Ground
No
Inspect EM013 and PI015 for corrosion, bent/pushed back pins or locate and repair the harness/connector PI001/025. Test the system for normal operation.
