ERASING DTCs
3120d 105
11. To prolong battery life, the Diagnostic Tool automatically shuts "Off"
after approximately three minutes with no button activity. The DTCs
retrieved will remain in the Diagnostic Tool's memory, and may be
viewed at any time. If the Diagnostic Tool’s batteries are removed,
or if the Diagnostic 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 Diagnostic 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 Diagnostic 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 but-
tons, as necessary, to highlight YES,
then press the ENTER
button.
„ If you do not want to proceed, use
the UP
and DOWN buttons,
as necessary, to highlight NO, then
press the ENTER
button to
cancel the erase procedure.
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.
