Pending code
- The pending code is a temporary malfunction code which differs from the DTC stored when the PCM or TCM detects a system malfunction.
- When the PCM or TCM detects a system malfunction, a DTC is stored in the PCM or TCM according to the number of drive cycles. On the other hand, the pending code is stored in the PCM or TCM regardless of the number of drive cycles.
- When the PCM or TCM determines that the system is normal, the pending code stored in the PCM or TCM is cleared from the PCM or TCM from the next drive cycle.
- Pending codes can be read out by implementing a quick check or an on-demand self-test using the M-MDS. (See DTC INSPECTION .)
