4.10.3 DTC Erased While Fault Remains
If fault codes are erased while the underlying issue remains unresolved, the fault
codes will reappear after a few drive cycles.
4.10.4 DTC Erased and Fault Fixed- History Code
If the fault has been fixed but a trouble code remains stored, the ECU may
sometimes detect the resolution and either clear the fault code or reclassify it as a
historical code.
4.10.5 DTC Erased and Fault Fixed- History Cleared
If the fault has been fixed and you clear the fault codes, the fault history will also be
erased. If another technician is going to investigate the issue, it’s not recommended
to clear the fault codes, as this may erase valuable information that could assist in
diagnosing the problem.
NOTE:
Clearing codes typically erases the freeze frame data associated with those codes.
4.10.6 PID Data
Displays PID data for various sensors from the vehicle electronic control module. This
Diagnostic Tool allows viewing real-time PID data of various sensors in a list, view
individual PID data in graphing, analog dashboard, view custom PID data up to 4
sensors in a list, individual graphing and merged graphing.
