-
Connect the 0-500-amp probe to the starter B+ Cable and to the VCMM .
-
Connect the VCMM and use the Oscilloscope option scaled to 100/A/Div. Add PIDS "Ambient Air Temp" and "Engine RPM".
-
Crank the engine, no more than 6 seconds at a time.
NOTE:
Allow 2 minutes between tests to allow for starter cooling to prevent overheat and damage to the motor.
-
Record the results, specifically Ambient Air Temperature
(AAT), Starter Current (Current Clamp) and Cranking speed (PCM signal
Engine_Speed).
-
Compare the results to the specifications in the workshop manual.
For
additional information, refer to: Specifications (303-06A Starting
System - 2.0L EcoBoost (177kW/240PS) – MI4, Specifications).
-
If both signals do not meet specification replace the starter motor.

System Operation
Exhaust Gas Recirculation (EGR) Systems
The EGR system controls the NOX
emissions. Small amounts of exhaust gases are recirculated back into
the combustion chamber to mix with the air to fuel charge. The
combustion chamber temperature is reduced, lowering NOX emissions
