1A-34 Engine General Information and Diagnosis:
DTC Table
S6RW0C1104006
NOTE
• There are two types of OBD system depending on the vehicle specification.
For non-Euro-OBD model, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• For non-Euro-OBD model, 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 CAN communication generic scan tool, only star (*) marked DTC No. in the following table
can be read.
• When DTC P0300 / P0301 / P0302 / P0303 / P0304 is detected, MIL blinks or lights up according to
detecting condition. For details, refer to “DTC P0300 / P0301 / P0302 / P0303 / P0304: Random Misfire
Detected / Cylinder 1 / Cylinder 2 / Cylinder 3 / Cylinder 4 Misfire Detected”.
