Diagnosis Procedure

OK: Voltage is 8 to 12 V.

a. The ignition switch remains in START position and check voltage of positive post of starter motor.

OK: Voltage is 8 to 12 V.

a. Remove starter motor.
b. Check if there is an open circuit or if it is stuck due to poor lubrication.

a. If malfunction only occurs in winter, Check if starter motor resistance is too strong because of improper 

engine lubricant and gear oil selection.

a. Check if engine internal mechanical resistance is too strong, causing starter motor not to run or run slowly.

Engine does not crank or cranks slowly while starting

1

Check voltage between two battery posts when engine starts

Replace battery

NG

2

Check voltage of positive post of starter motor

OK

Repair or replace wire harness

NG

3

Check operation of starter motor

OK

Repair or replace starter

NG

4

Check engine lubricant and gear oil

OK

Replace lubricant with appropriate 
number

NG

5

Check engine internal mechanical resistance

OK

Check and repair engine internal 
resistance

NG
