OBD-II Pending Trouble Code

WARNING: This page is about a different variant/trim than selected.

These appear when a problem is detected in a monitored system. The code for a failed system is stored in the PCM memory in the first drive cycle. This code is called the pending code. If the PCM judges that the system returned to normal or the problem was mistakenly detected, deletes the pending code. If the problem is found in the second drive cycle too, the PCM judges that the system has failed, and the DTC is stored.
