Charging System: Troubleshooting: Notes

NOTE:

Be careful not to short-circuit the wiring by the body or other wirings.
In case of discharging problem, measure parasitic current at all times.
(Refer to Charging System - "BATTERY ")
When checking the alternator main fuse, perform continuity test and voltage test between terminals as well as visual check to confirm normal operation.
When measuring parasitic current, if the battery (-) terminal is disconnected, it may be displayed as normal due to initialization, so measure using a clamp type ammeter without removing the (-) terminal.
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 misassembly 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 guide and ETM.
