Understanding the DTC (Diagnostic Trouble Code)
A four-digit DTC is shown through the flashing pattern of the EPS indicator light. A number between 1 and 9 is
represented by the number of times that the EPS indicator light lights up in interval of 0.3 seconds and the separation
between the each digit are indicated by the light staying off for 1 seconds. In addition, the separation between the start
code and the DTC is indicated by the light being off for 3 seconds. After the start code is displayed, DTCs appear from
the smallest number code.
If no DTCs are memorized, the EPS indicator light keeps blinking by the four times at same interval.
Use of SDS
NOTE
• Don’t disconnect couplers from EPS
control unit, the battery cable from the
battery, EPS control unit ground wire
harness from the engine or main fuse
