Using the Code Reader
ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
OBD2 55
When DTCs are erased from the vehicle's computer memory,
the I/M Readiness Monitor Status program resets the status of
all Monitors to a not run "flashing" condition. To set all of the
Monitors to a DONE status, an OBD2 Drive Cycle must be
performed. Refer to your vehicle's service manual for
information on how to perform an OBD2 Drive Cycle for the
vehicle under test.
The Code Reader must be
connected to the vehicle’s DLC to
erase the codes from the
computer’s memory. If you press
the ERASE
button when the
Code Reader is not connected to
the vehicle’s DLC, the erase
instruction screen displays.
The Erase function can be performed only from the OBD2
DTC screen. The Erase function cannot be performed while
the Code Reader is in "enhanced" mode.
