DEFINITION OF TERMS
| Term | Definition |
|---|---|
| Monitor description | Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details). |
| Related DTCs | Diagnostic code |
| Typical enabling condition | Preconditions that allow the ECM to detect malfunctions. |
| Typical enabling condition | With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the malfunction threshold(s). |
| Sequence of operation | The priority order that is applied to monitoring, if multiple sensors and components are used to detect the malfunction. |
| Sequence of operation | While another sensor is being monitored, the next sensor or component will not be monitored until the previous monitoring has concluded. |
| Required sensor/components | The sensors and components that are used by the ECM to detect malfunctions. |
| Frequency of operation | The number of times that the ECM checks for malfunctions per driving cycle. |
| Frequency of operation | "Once per driving cycle" means that the ECM detects malfunction only one time during a single driving cycle. |
| Frequency of operation | "Continuous" means that the ECM detects malfunction every time when enabling condition is met. |
| Duration | The minimum time that the ECM must sense a continuous deviation in the monitored value(s) before setting a DTC. This timing begins after the "typical enabling conditions" are met. |
| Malfunction thresholds | Beyond this value, the ECM will conclude that there is a malfunction and set a DTC. |
| MIL operation | MIL illumination timing after a defect is detected. |
| MIL operation | "Immediately" means that the ECM illuminates MIL the instant the ECM determines that there is a malfunction. |
| MIL operation | "2 driving cycle" means that the ECM illuminates MIL if the same malfunction is detected again in the 2nd driving cycle. |
| Component operating range | Normal operation range of sensors and solenoids under normal driving conditions. |
| Component operating range | Use these ranges as a reference. |
| Component operating range | They cannot be used to judge if a sensor or solenoid is defective or not. |

- MONITOR DRIVE PATTERN FOR ECT TEST Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions. (The DTCs may not be detected due the actual driving conditions. And some codes may not be detected through this drive pattern). HINT: Preparation for driving Warm up the engine sufficiently. (Engine coolant temperature is 60°C (140°F) or higher) Drive the vehicle when the atmospheric temperature is -10°C (14°F) or higher. (Malfunction is not detected when the atmospheric temperature is -10°C (14°F) or less) Driving note Drive the vehicle through all gears. Stop -> 1st -> 2nd -> 3rd -> O/D -> O/D (lock-up ON). Repeat the above driving pattern three times or more. NOTE: The monitor status can be checked using the OBDII scan tool. When using the hand-held tester, monitor status can be found in the "ENHANCED OBD II/DATA LIST" or under "CARB OBD II". In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other factors) the drive pattern can be resumed and, in most cases, the monitor can be completed. CAUTION: Perform this drive pattern on a level road as much as possible and strictly observe the posted speed limits and traffic laws while driving. HINT: *1: Drive at such a speed in the uppermost gear, to engage lock-up. The vehicle can be driven at a speed lower than that in the above diagram under the lock-up condition.
