ISO OVERCHECK PROCEDURE
.
The Overcheck section of this plan has been developed in
conjunction with the Original Equipment Manufacturer.
Providing all values are achieved, the pump settings will
maintain the original homologated engine performance. Failure to
attain any one of the values will indicate a pump setting or
function failure and require further investigation.
