OBD-II Pending Trouble Code
OBD-II PENDING TROUBLE CODE [MZR 2.5]
- 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 determines that the system has returned to normal or the problem was mistakenly detected, it deletes the pending code. If the problem is found in the second drive cycle, too the PCM determines that the system is malfunctioning, and the DTC is stored.
