X5: Check Continuity Harness

NOTE: To avoid a spurious result, disconnect connectors: EM011 (ECM), and PI042 and PI006 (electronic throttle body)







Measure the resistance between EM010/020 and the MAF meter connector PI035/004

- Is the resistance < 0.5 ohms?
Yes
GO to X6 X6: End
No
Inspect harness/connector (PI001/031) and splice EMS002. Repair as necessary. Reconnect PI042 and PI006 (electronic throttle body), EM010, EM011 (ECM) and PI035 (MAF meter). Test the system for normal operation.
