7. Check engine speed during cranking.

Is engine speed above 100 rpm (min-1)?

YES - Go to step 8.

NO - Remove and disassemble the starter and check for the following until you find the cause.

- Excessively worn starter brushes
- Open circuit in commutator brushes
- Dirty or damaged helical splines or drive gear
- Faulty drive gear clutch

8. Check the cranking voltage and current draw.

Is cranking voltage no less than 9.0 V and current draw no more than 150 A for D14Z6, D16V1 (KE model), D16V3 engines, 8.0V and 200 A for D16V1 (KG, KR, KS models) engine with A/T, or 8.0 V and 300 A for D16V1 (KG, KR, KS models) engine with M/T?

YES - Remove the starter and inspect its drive gear and the flywheel or torque converter ring gear for damage. Replace any damaged parts.

NO - Remove and disassemble the starter and check for the following until you find the cause.

- Open circuit in starter armature commutator segments
- Starter armature dragging
- Shorted armature winding
