Fault Codes:
Hyundai HX220 NL EPFC 2638（5298-17）
Fault Description:
Aftertreatment diesel oxidation catalyst conversion efficiency -Data valid but below normal operating range -Least severe level.The temperature increase across the aftertreatment diesel oxidation catalyst is lower than expected. The conversion efficiency of the post-treatment diesel oxidation catalytic converter - the data is valid but below the normal operating range (the lowest severity level). The temperature rise of the post-treatment oxidation catalyst was detected to be lower than expected
Fault Location:
Possible frequent need for aftertreatment regeneration. Frequent post-processing regeneration may be required
