CLEARING DIAGNOSTIC TROUBLE CODES (DTCS)
Depending on what diagnostic process you
follow, it may be necessary to clear the DTCs
and test the system again. Again, don't forget
to record the DTCs on your diagnostic
worksheet. The codes may or may not come
back after you have cleared them.
To clear the DTCs, click on the "Clear DTCs" tab
at the bottom right of the screen. This will
erase ALL of the DTCs that are stored in
memory.
Once you have clicked the clear DTCs option,
you will be prompted to confirm that you really
do want to perform this action. Before clicking
yes, make sure that this is the action you want
to perform, as it cannot be undone.
Clearing the DTCs can take up to a few
minutes to perform. This is because the tool
must communicate with every module in the
vehicle and clear the codes in the module if
one exists. Some vehicles today have upwards
of 20 different modules that the scan tool will
have to communicate with and test. Be patient and do not interrupt this process.
After clearing the codes you may want to test the system again and see if the trouble codes
come back. This is a good way to verify repairs to such things as loose wires to modules or
sensors or the replacement of components.
