To prolong battery life, the Code Reader automatically shuts
“Off” approximately three minutes after it is disconnected from
the vehicle. The DTCs retrieved, Monitor Status and Freeze Frame
data (if any) will remain in the Code Reader’s memory, and may
be viewed at any time by turning the unit “On”. If the Code
Reader’s batteries are removed, or if the Code Reader is re-
linked to a vehicle to retrieve codes/data, any prior codes/data in
its memory are automatically cleared.

ERASING DIAGNOSTIC TROUBLE CODES (DTCs)

When the Code Reader’s ERASE function is used to erase
DTCs from the vehicle's on-board computer, "Freeze
Frame" data and manufacturer-specific enhanced data
are also erased.

If you plan to take the vehicle to a Service Center for repair, DO NOT
erase the codes from the vehicle's computer. If the codes are erased,
valuable information that might help the technician troubleshoot the
problem will also be erased.

Erase DTCs from the computer's memory as follows:

When DTCs are erased from the vehicle's computer memo-
ry, the I/M Readiness Monitor Status program resets the sta-
tus of all Monitors to a not run "flashing" condition. To set all
of the Monitors to a DONE status, an OBD 2 Drive Cycle
must be performed. Refer to your vehicle's service manual for
information on how to perform an OBD 2 Drive Cycle for the
vehicle under test.

The Code Reader must be con-
nected to the vehicle’s DLC to
erase the codes from the comput-
er’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.

1. If not connected already, connect the

Code Reader to the vehicle's DLC, and
turn the ignition "On.” (If the Code Reader
is already connected and linked to the
vehicle's computer, proceed directly to
step 4. If not, continue to step 2.)

2. Turn the ignition on. DO NOT start the

engine.

Press and release the

POWER/LINK

button to establish

communication with the vehicle's com-
puter.
