EPS(MDPS=Motor Driving Power Steering) uses an electric motor to provide directional contol to the driver. EPS Control Module has a charging circuit to supply current to a motor temoporarily.
EPS(MDPS=Motor Driving Power Steering)ECU sets this code and turns on warning lamp if charged voltage is too low due to a abnormal charging circuit. At that time EPS ECU inhibits it's own function.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Check voltage | 1. Poor connetion in power circuit 2. Poor connection in ground circuit 3. Over charging |
