Is the problem found?
 | ▶ Repair the trouble causing part and go to "Verification of Vehicle Repair". |
 | ▶ Go to "Power Circuit Inspection". |
Generally, Power voltage or current is not supplt to Start motor after Engine start. If Power voltage or current supply to Start motor after Engine start, It could be incur critical damage with Start motor and Fly-wheel.So thar ECU monitoring srarting circuit in order to prevent from damage.
P0617 is set when the high current detected for 1second after Engine running

Electrical systems consist of a lot of harness and connectors, poor connection of terminals can cause various problems and damge of component.
Perform checking procedure as follows.
Check damage of harness and terminals : Check terminals for contact resistance, corrosion and deformation.
Check connecting condition of ECM and component connector : Check terminal seperation, damage of locking device and connecting condition between terminal and wiring.
Disconnect the pin which requires checking at male connector and insert it to the terminal at female connector for checking connecting condition. ( after checking, reconnect the pin at correct position. )

IG key OFF .
Disconnect 'ECM' connector.
MT : step on CLUTCH pedal, AT : 'N' position.
Measure the resistance between Relay control terminal of wiring side and chassis ground.
Specification : Infinity
Is the measured resistance within the specification ?
| ▶ Go to "Component Inspection". |
| ▶ Repair short/open in power circuit and go to "Verification of Vehicle Repair". |
Check 'START RELAY' component coil resistance
IG KEY "OFF", ENGINE "OFF".
Disconnect 'START RELAY'.
Measure the resistance of 'START RELAY' component coil.
Specification : 55±5 Ω (20℃)
Is the measured resistance within the specification?
| ▶ Go to "2. Check 'START RELAY' component operation" as follows. |
| ▶ Replace 'START RELAY' and go to "Verification of Vehicle Repair". |
Check 'START RELAY' component operation
IG KEY "OFF", ENGINE "OFF".
Disconnect 'START RELAY'.
Supplies random B+ and ground to coil sides of glow relay ( terminal 85, terminal 86).
Check continuity between glow relay terminal 30 and terminal 87.
Specification : When power is supplied : Continuity ( below 1.0Ω )
When power is not supplied : Discontinuity ( Infinite Ω )
Is the measured resistance within the specification?
| ▶ Go to "Verification of Vehicle Repair". |
| ▶ Replace 'START RELAY' and go to "Verification of Vehicle Repair". |
※ Repeat this process 2~3 times.
After a repair, it is essential to verify that the fault is corrected.
After connecting GDS select "Diagnostic Trouble Codes(DTCs)" mode to and then clear DTC.
Drive the vehicle within DTC Enable conditions in General information.
After selecting "Diagnostic Trouble Codes(DTCs)" mode and check DTC is recorded again.
Are any DTCs recorded ?
| ▶ Go to the DTC guide of recorded NO. in GDS. |
| ▶ System operates within specification. |
