Using the Diagnostic Tool
ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
OBD2 43
The Diagnostic information retrieved can be transferred to a
personal computer (PC) with the use of an optional Tek-Link
program. See documentation that comes with program for
instructions.
ERASING DIAGNOSTIC TROUBLE CODES (DTCs)
When the Diagnostic Tool’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. "Permanent" DTCs ARE NOT erased
by the ERASE function.
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 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 Diagnostic Tool 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
Diagnostic Tool is not connected
to the vehicle’s DLC, the erase
instruction screen displays.
1. If not connected already, connect the
Diagnostic Tool to the vehicle's DLC, and
turn the ignition "On.” (If the Diagnostic
Tool is already connected and linked to
the vehicle's computer, proceed directly
to step 3. If not, continue to step 2.)
2. Perform the Code Retrieval procedure
as described on page 19. Wait until the
codes are displayed on the Code
Readers LCD and then proceed to step
3.
3. Press and release the ERASE
button. A confirmation message shows
on the LCD display.
- If you are sure you want to proceed
press the ERASE
button again to
erase DTCs from the vehicle’s computer.
