Reading Trouble Codes:
When viewing codes, the scan tool displays both Diagnostic Trouble
Codes (DTC) and Pending DTCs.
A DTC indicates a malfunction is present. It must be present for a
sufficient amount of time before the tool will display a Diagnostic
Trouble Code, and a Malfunction Indicator Light (MIL). MIL is also
known as , Service Engine Soon or Check Engine Light.
MIL codes will remain stored in the vehicle’s memory until the fault is
repaired.
Pending DTC codes, are also known as, “continuous monitor” and
“maturing codes.” An intermittent fault will cause the vehicle’s
computer to store a code in memory. If the fault does not occur
within 40 warm-up cycles, the code will be cleared from memory. If
the fault occurs a specific number of times, the code will mature into
a DTC and the MIL will turn on.
Important Note:
If there are factory definition error codes,
select the error code and then select the corresponding vehicle
manufacturer (i.e. Ford, GM…). to decipher the specific error code
for your vehicle.
