Daewoo Novus M2SEF - Engine Diagnostic Codes; How to Read Engine Diagnostic Codes

1-31 HOW TO HANDLE THE VEHICLE
* DDC Engine
1. How to read engine diagnostic codes
Code 13(SEL Active codes) Code 21(CEL Inactive codes)
SEL ⇔ SEL SEL SEL ⇔ CEL CEL ⇔ CEL
1 Flash 3 Flashes 2 Flashes 1 Flash
The active code will be flashed on the SEL(code "25" if there is no malfunction code). Then the inactive
code will be flashed on the CEL(code "25" if there is no malfunction code).
The process of flashing all the inactive codes will repeat until the conditions for code flashing are no longer
satisfied.
