1.INJECTOR COMPENSATION CODE
УКАЗАНИЕ:
  1. Each injector has different fuel injection characteristics. In order to optimize fuel injection performance, the ECM compensates for these differences by adjusting the fuel injection duration of each injector according to its compensation code. Injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each injector.
  2. If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened

  2. When the ECM is changed, all of the existing injector compensation codes must be input into the new ECM (see page RAV4_ACA30 RM000000TJ400AX.html).
