P148698 — On-board charger over-temperature
Quick answer
P148698 indicates that the on-board charger measured its coolant running too hot, so it stops charging to protect itself. This usually points to low coolant, a leak or a cooling fan problem.
What to check first
- Read all stored fault codes with a scan tool and deal with related codes first.
- High-voltage system: do not open or disconnect high-voltage components. Refer the car to a technician qualified for high-voltage work.
Can I still drive?
Have it inspected before further driving. If in doubt, park the car and ask a technician — a fault that limits power or shuts the high-voltage system down will not clear by itself.
