- IG "ON" & Monitor that any different DTC (Diagnostic Trouble Code) is existed.
(There will be at least one more DTC which causes this DTC P2105 to retrieve)
- P2105 will be stored in addition to related ETS codes.
Repair the cause of the related codes and perform ETS initialization before troubleshooting P2105.
- Is the same DTC occurred?
YES
- Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by ECM. Before or after testing ECM on the vehicle, use this function before reusing the ECMNO
- Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
Procedure of ETS Initialization
