11. To prolong battery life, the scan tool automatically shuts "Off" after
approximately three minutes with no button activity. The DTCs
retrieved will remain in the scan tool's memory, and may be viewed
at any time. If the scan tool’s batteries are removed, or if the scan
tool is re-linked to a vehicle to retrieve codes, any prior codes in its
memory are automatically cleared.
12. Follow the testing and repair procedures outlined in the vehicle's service
repair manual to correct "hard" DTCs. Codes should be addressed and
eliminated in the order they were received, erasing and retesting after
each repair is made to be sure the fault was eliminated.
ERASING DTCs
When the scan tool's ERASE function is used to erase
DTCs from the vehicle's on-board computer, manufacturer
specific data (where applicable) is 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 DTC’s from the computer’s memory as follows:
1. Connect the scan tool to the vehicle’s DLC. Press the ENTER
button to continue.
2. Turn the ignition ON. DO NOT start the engine.
3. Press and release the ERASE
button. A confirmation message
shows on the LCD display.
 If you are sure you want to proceed,
use the UP
and DOWN
buttons, as necessary, to highlight
YES, then press the ENTER
button to continue.
- If you do not want to proceed,
use the UP
and DOWN
buttons, as necessary, to
highlight NO, then press the
ENTER
button to exit the
erase function.
4. If you chose to erase DTCs, the “To erase
DTC’s consult the vehicle’s service repair
manual...” screen displays. You must
consult the vehicle’s service repair manual
for procedures to erase DTCs.
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.
