Vehicle S/W Management: Notes
WARNING: This page is about a different car, the 2017 Kia Niro. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- Check the connector status of the HCA after removing the undercover under the vehicle.
- If the connector is not properly connected, check the system after connecting the connector normally.
- Check the HCA connector terminal for corrosion.
- If the engine clutch system is leaking, replace the leaking area.
- If there is no connector defect or corrosion, proceed to step 2.
- Clear the DTC and use the KDS/GDS to perform "Engine Clutch/Motor Resolver Adaption" and check the DTC.
- If the same DTC occurs, proceed to step 3.
- If the same DTC does not occur, check whether another DTC has occurred.
- If the "Engine Clutch/Motor Resolver Adaption" fails, take action according to the reason for failure.
- Check the following parts in current data at ignition "ON" (Not READY) after ignition "OFF" for 5s.
- If the operating position of the engine clutch actuator is more than -4.0mm, replace the HCA.
- Replace the HCA if the operating position of the engine clutch actuator is located near -4.5mm but the operating pressure of the engine clutch actuator is over 1.4 bar.
- After replacing the engine clutch actuator, (1) "Initialization of the engine clutch inspection line learning and diagnostic information"→ (2) "Removal of air from clutch hydraulic pressure line"→(3) "Engine Clutch/Motor Resolver Adaption"→(4) "Stabilization of the engine clutch hardware transfer torque" must be sequentially performed.
* If the SOC is less than 35% and the gear is P position in the HEV "Ready" state, the engine will operate and the SOC will be charged.
* When "Removal of air from engine clutch hydraulic pressure line" is performed after replacing the engine clutch system, the brake oil temperature must be over 20°C (68°F) to perform normally.
