CODING LIST
CAUTION:
With the ETACS functions being customized, if any of the ETACS-ECU variant coding and option coding items are changed, the customized contents are reset. In such case, the functions need to be recustomized.
Before troubleshooting, check that the coding data written into the engine control module, SRS-ECU and ETACS-ECU are normal. If they are not the same as the initial settings, various functions and systems will not work correctly.
