OBD PENDING TROUBLE CODE [LF]
B3E010200102W03
• 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 problem is not
found in a second drive cycle, the PCM judges that the system returned to normal or the problem was
mistakenly detected, and deletes the pending code (1DC). If the problem is not found in a second drive
cycle, the PCM judges that the system returned to normal or the problem was mistakenly detected, and
deletes the pending code when the ignition switch is turned to the ON position in the next drive cycle
