5.2.1 Read Codes
Read Codes menu lets you read trouble codes found in the control unit.
Typical code status include:
● Present/Permanent/Current Codes
● Pending Codes
● History Codes
Present/Permanent/Current 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.
History codes are also referred to as past codes that indicate intermittent DTCs that are not currently
active.
To read codes from a vehicle:
1. Scroll with the arrow keys to highlight Read Codes from Function Menu and press the ENTER key. A
code list including code number and its description displays.
2. Use the up and down arrow keys to scroll through data to select lines, and left and right arrow keys
to scroll back and forth through different screens of data.
