* DDC Engine

1. How to read engine diagnostic codes

Code 13(SEL Active codes)
⇔
SEL
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.
