In the case of long code definitions, a small arrow is shown in the 
upper/lower right-hand corner of the code display area to indicate 
the presence of additional information. Use the 
 button to view 
the additional information. 
Code 12 will always be present and it has one of the following meanings: 
„
 
If code 12 is the only DTC retrieved and your vehicle "STARTS OK" 
then code 12 indicates system "PASS" and all computer control 
systems are functioning properly. 
„
 
If code 12 is present and your vehicle "DOES NOT START", then it 
may indicate a problem with the ignition control system. 
7.
  Disconnect the Scan Tool from the vehicle and turn the ignition key 
OFF. 
8.
  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. 
9.
  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. Code 12 will appear alone when no other fault codes are 
present. 
„
 
It may be necessary to test drive the vehicle to reset "hard" fault 
codes 13, 15, 24, 44, 45, and 55 after they have been erased. 
Whenever codes 51, 52, 54, or 55 are displayed with other 
codes, troubleshoot and eliminate the "50 Series" codes first, 
then proceed with the lower numbered codes. 
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.
