EPS uses an electric motor to provide directional contol to the driver. EPS CM always monitors voltage of the motor because current of the motor is controlled by voltage.
Three phase current of the motor is controlled by three phase voltage. EPS CM sets this code and inhibits EPS control if these voltage values are different from predefined value.
Item | Detecting Condition | Possible cause |
DTC Strategy | ● Check Motor voltage | ● Faulty Motor ● Faulty ECU voltage sensor |
Enable conditions | ● Engine ON | |
Threshold value | ● Comparion voltage not the same | |
Fail Safe | ● EPS warning lamp ＂ON＂ | |
Restoration conditions | ● Normal condition after IG on → off |
