Toyota injector coding is registering the calibration values on an injector to the engine control unit. It is critical on many common-rail diesels; the same requirement does not apply to every gasoline model.
It differs from general toyota-coding option coding; toyota-adaptation may be required afterward.
Workflow (general)
- Read the injector code correctly
- Write it to the corresponding cylinder channel
- Check fault memory; complete the learning process
- Idle and road test

Workshop notes
A single-character code error can cause cylinder imbalance.
On Hilux diesel jobs, evaluate alongside the DPF (toyota-dpf-reset).
Don't dismiss fuel pressure issues by attributing them to the code alone.
Correct code entry can be critical for cylinder balance.
