The Meter is an important part of the vehicle.
The Meter works together with the EPS system
and monitors working condition of the EPS
system.
Faults can be displayed by a fault indicator light
and fault indicator of EPS system, so the driver
can acknowledge faults of the EPS in time and
take some measures to keep himself/herself
safe.
When a fault occurs on the EPS system, a fault
indicator light will be on. At the same time, the
fault indicator of EPS system will display the
fault code for maintenance.
