13.3.10.1 Wait To Disconnect Indicator Operation
The wait to disconnect Indicator is a mandatory fit item used to alert the
machine operator that the Engine & DEF system are still active and the
battery isolation switch should not be used. Post ignition off, the DEF system
must perform a fluid purge cycle that requires the use of the DEF pump motor.
If system power is removed during the purge cycle the fluid left within the
pumps and the DEF lines may cause component failures. Further information
regarding the purge operation is shown in section 16 of this document.
