Charging System - 1.6L T: Troubleshooting
NOTE:
- Be careful not to short-circuit the wiring by the body or other wirings.
- In case of discharging problem, measure dark current at all times.
(Charging System - "Dark Current Inspection").
- When checking the alternator main fuse, perform continuity test and voltage test between terminals as well as visual check to confirm normal operation.
- When checking the ground, repair or replace after inspecting for defective ground cable, defective installation or defective contact due to foreign object.
- It is not recommended to use non-authentic parts as installing non-authentic parts may cause malfunction of charging system.
- Be careful as disassembly may cause short-circuit of wiring, which may result in battery discharge.
- As it will reset and appear as normal if the battery negative (-) terminal is disconnected while measuring dark current, measure by using a hook meter without disconnecting the negative (-) terminal.
- Note that there may be various phenomenons/possible causes/repair measures apart from above.
- For more effective repairs, refer to DTC INDEX
