Oil and Chemical Type 

Sealant
Type: TB1217C or equivalent
CAUTION:
  • If the characteristic value of a new coupling component is not input to the PCM or the characteristic value is input incorrectly after replacing the coupling component, it could result in the following conditions.
    • The system does not operate normally.
    • A problem with durability of the coupling component occurs.
      • After replacing the coupling component, read out the characteristic value of a new coupling component and write it to the PCM. (See COUPLING COMPONENT CALIBRATION DATA WRITING .)
      • Read out the characteristic value of the coupling component from the label or mark shown in the figure.
