5.1 Reading DTCs
The
Read Codes
function is used to read DTCs (stored
codes), which are used to help identify the cause of a trouble
or troubles with a vehicle, and pending codes from the
vehicle’s control modules.
√ When emission-related or drivability fault occurs the
control module illuminates the malfunction indicator
lamp (MIL).
√ Pending Codes are also referred to as continuous
monitor or 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 fault occurs a specific
number of times, the code matures into a DTC and the
MIL illuminates or blinks.
√ This function can be performed with KOEO or KOER.
