Replacement
1. Replacement is the reverse of the removal procedure.
2. If the registration / preheat assembly has been removed, perform the dC625 Registration
/ Preheat Calibration.
NOTE: W/TAG 018 machines do not have air pumps install as standard. However, the preheat
air pumps in a replacement registration/preheat assembly will function when the unit is
installed.
These W/TAG 018 machines will have their NVM written (independent of software version)
such that PEST pump open faults 99-730 are not reported. This NVM will remain written across
software reloads and NVM initializations. To restore the PEST pump open fault NVM, perform
the following:
1. Find the first unused NVM field in the range 498-002 through 498-017. The field is consid-
ered unused if its value is -1.
2. Write this field with the value 730.
