Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The engine control module (ECM) stores information about fuel trim in the various adaptation ranges. The diagnostic trouble code (DTC) is stored if the engine control module (ECM) detects that one of the codes for fuel trim (bank 1) is stored in two consecutive operating cycles. The diagnostic trouble code is a collective code for diagnostic trouble codes having to do with the fuel adaptation. The diagnostic trouble code is always stored together with one of the following diagnostic trouble codes:
- ECM-210C
- ECM-210D
- ECM-212C
- ECM-212D
- ECM-216C
- ECM-216D
If any or some of these diagnostic trouble codes above are stored, then troubleshoot these according to each troubleshooting.
