Issue
The customer may experience a whirring/grinding noise while cranking
the engine. In some cases the vehicle will not crank
In addition, both the starter motor and the flywheel gear may be
worn/damaged – see attached photos
Cause
The starter motor harness link wires are incorrectly positioned in the
connector cavities – this could be in either connector C11-Z2 or
C1DC73DA. This can cause the starter motor pinion to rotate before
engaging the flywheel ring gear
Action:
Check the starter motor harness link wiring connectors are correctly
populated, as follows:
C11-Z2 – Starter motor link harness to engine harness (See picture)
Cav Color
1 BN-WH
2 GY-BU
C1DC73DA – Starter motor (See Picture)
