DTC Type
Description
Confirmed codes are reported when a
component, sensor, or other part of the
Confirmed
vehicle is indication a malfunction is pres-
ent.
Codes transmitted through the PCMs da-
ta stream when a trouble condition is ac-
Current
tive and cannot be erased. The problem
must be repaired to remove the DTC.
Pending codes are also referred to as
continuous monitor or maturing codes.
An intermittent fault causes the control
module to store a code in memory. If the
fault does not occur within a certain num-
Pending
ber of warm-up cycles (depending on ve-
hicle), 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
used with KOEO or KOER.
Examples of Read Codes information screens follow.
In this example, module (MOD) $18 is reporting the
DTCs.

After servicing the vehicle, erase stored DTCs and verify
no codes have returned. If a DTC returns, problem has
not been fixed or other faults are present.

function.

may need to be driven and the monitor ran before con-
cluding that the fault is repaired.
