|---|---|
| Monitor Description | Description of what ECM (Included in HV control ECU) monitors and how detects malfunctions (monitoring purpose and its details). |
| Related DTCs | A group of diagnostic trouble codes that are output by ECM (Included in HV control ECU) based on same malfunction detection logic. |
| Typical Enabling Condition | Preconditions that allow ECM (Included in HV control ECU) to detect malfunctions. With all preconditions satisfied, ECM sets DTC when monitored value(s) exceeds malfunction threshold(s). |
| Sequence of Operation | Order of monitor priority, applied if multiple sensors and components involved in single malfunction detection process. Each sensor and component monitored in turn and not monitored until previous detection operation completed. |
| Required Sensor/Components | Sensors and components used by ECM (Included in HV control ECU) to detect each malfunction. |
| Frequency of Operation | Number of times ECM (Included in HV control ECU) checks for each malfunction during each driving cycle. "Once per driving cycle" means ECM only performs checks for that malfunction once during single driving cycle. "Continuous" means ECM performs checks for that malfunction whenever enabling conditions met. |
| Duration | Minimum time for which ECM (Included in HV control ECU) must detect continuous deviation in monitored value(s) in order to set DTC. Timing begins when Typical Enabling Conditions met. |
| Malfunction Thresholds | Value, beyond which, ECM (Included in HV control ECU) determines malfunctions exist and sets DTCs. |
| MIL Operation | Timing of MIL illumination after detected. "Immediate" means ECM (Included in HV control ECU) illuminates MIL as soon as malfunction detected. "2 driving cycle" means ECM illuminates MIL if same malfunction detected second time during next sequential driving cycle. |
