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
