DTC Table

S5JB0E1104005

NOTE

• For the vehicle equipped with diagnosis connector, some of DTC No. with delta (U) mark in the 

following table can not be detected by ECM depending on vehicle specification and local regulation.

• With the generic scan tool, only star (*) marked DTC No. in the following table can be read.
• 1 driving cycle: MIL lights up when DTC is detected during 1 driving cycle.
• 2 driving cycles: MIL lights up when the same DTC is detected also in the next driving cycle after 

DTC is detected and stored temporarily in the first driving cycle.

• *2 driving cycles:

MIL blinks or lights up. Refer to “DTC P0300 / P0301 / P0302 / P0303 / P0304: Random Misfire 
Detected / Cylinder 1 / Cylinder 2 / Cylinder 3 / Cylinder 4 Misfire Detected in related manual” for
