Innova CanOBD2&1 Owner's Manual page 115

If the erase was not successful, an
advisory message shows on the
CanOBD2&1 Scan Tool's display.
Verify that the CanOBD2&1 Scan
Tool is properly connected to the
vehicle's DLC and that the ignition is
ON. If the erase process still does
not complete, turn the ignition OFF,
wait 10 seconds, then turn back ON
and repeat steps 2 and 3.
FORD systems will not display an erase was not successful
message. If the "One moment please erase in progress"
message on the display does NOT change after 3 minutes, it
indicates that the erase function has failed. Check the DLC
connections and make sure the ignition key is "ON". Perform
the ERASE function again.
Erasing DTCs does not fix the problem(s) that caused the
code(s) to be set. If proper repairs to correct the problem that
caused the code(s) to be set are not made, the code(s) will
appear again and the check engine light will illuminate as soon
as the problem that cause the DTC to set manifests itself.
