and relay box.

2. Check starter relay.

a. Using a digital multimeter, measure resistance according to the value(s) in the table below.

Precautions for Starting System

1. For models with PEPS system, shift the transmission to P or N before starting and firmly depress the clutch 

pedal (for MT model) or brake pedal (for CVT model) until engine switch indicator illuminates in green.

2. For models without PEPS system, shift the transmission to neutral and apply parking brake before starting, 

and depress the clutch pedal while starting.

3. For models with PEPS system, power supply mode (LOCK, ACC, ON) is always stored in vehicle. When 

the battery cable is disconnected and reconnected, the power supply returns to the mode it was in before 
the battery cable was disconnected. Be sure to turn engine switch off before disconnecting the cable from 
battery terminal. Be careful if the power supply condition before the battery became depleted is not known.

4. Make sure that battery is fully charged to reduce the repeat operating time of starter.



After the battery is disconnected and reconnected, be sure to wait 10 seconds or more before engine start. 
The engine may not start immediately after battery is reconnected.

5. Do not start engine for more than 5 seconds each time, the repeat starting time should be not less than 



10 - 15 seconds, and the consecutive starting is not allowed more than 3 times.

6. If starter cannot stop, turn off ignition switch immediately, or remove negative battery cable to find the 

problem.

7. Check starter circuit frequently to make sure that each wire for starting system is connected securely and 

in good insulation.

8. Generally, perform maintainable service for starter when servicing the vehicle. Also, the maintenance 

interval can be shortened or extended properly depending on actual conditions.

9. Remove the negative battery cable before removing the starter.

Diagnosis Procedure

HINT:
Perform troubleshooting according to the procedures below.

HINT:
In troubleshooting, confirm that the problem symptoms have been accurately identified. Preconceptions 
should be discarded in order to make an accurate judgement. To clearly understand what the problem 
symptoms are, it is extremely important to ask the customer about the problem and the conditions at the time 
the malfunction occurred.

Standard voltage: 11 to 14 V
If voltage is below 11 V, recharge or replace the battery before proceeding to next step.
