READ CODES
The Read Codes function retrieves DTCs from the vehicle’s computer module(s).
This function can be performed with the KOEO or KOER. There are two types of
codes, Malfunction Indicator Lamp (MIL) codes and Pending codes.
• MIL Codes: These codes cause the computer to illuminate the MIL when an
emission related or driveability fault occurs. The MIL is also known as the
“service Engine Soon” or “Check Engine Lamp”. MIL codes remain in the
vehicle’s memory until the fault is repaired.
• Pending Codes: These codes are also referred as “continuous monitor” and
“maturing codes”. An intermittent fault will cause the 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. If the DTC is a pending
code, then the icon (
V
) displays next to the DTC number.
