Air Mass Flow Rate (AMFR) Adaptation

The AMFR adaption value should be no lower than -4.2 kg/hr and no greater than +2.8 kg/hr for both normally aspirated and super charged engines.

Note:
Where values are less than 1 kg/hr, the PDU display will show the values as g/hr, for example 500 g/hr rather than 0.5 Kg/ hr. (Illustration 1).

Allow the vehicle to idle until the AMFR adaption value changes and then stabilizes; if the adaption is within the above values then the previous flow chart repair has been successful. If the adaption is still outside of the above values then continue to follow the flow chart until the fault is found.

After the completion of each flow chart repair, dump the trace snapshot into the trace buffer; which can then be printed out and be used for Warranty Audit Purposes.
