5.2 Read Codes
Read Codes menu lets you read both stored codes and pending codes found in the control unit.
Typical menu options include:
●
Stored Codes
●
Pending Codes
Diagnostic trouble codes stored in a control module are used to help identify the cause of a
trouble or troubles with a vehicle. These codes have occurred a specific number of times and
indicate a problem that requires repair.
Pending codes are also referred to as maturing codes that indicate intermittent faults. If the fault
does not occur within a certain number of drive cycles (depending on vehicle), the code clears
from memory. If a fault occurs a specific number of times, the code matures into a DTC and the
MIL illuminates or blinks.
