Toyota RAV4 (XA40) 2013-2018 Service Manual: Definition of terms
| Terms | Definition |
| Monitor description | Description of what ecm monitors and how detects malfunctions (monitoring purpose and details). |
| Related dtcs | Group of diagnostic trouble codes that are output by ecm based on same malfunction detection logic. |
| Typical enabling condition | Preconditions that allow ecm 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, when previous detection operation completed. |
| Required sensor/components | Sensors and components used by ecm to detect each malfunction. |
| Frequency of operation | Number of times ecm 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 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 determines malfunctions exist and sets dtcs. |
| Mil operation | Timing of mil illumination after malfunction detected.
"Immediate" means ecm 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. |

Vc output circuit
Description
The ecm constantly generates 5 v power from the battery voltages supplied to
the +b (batt) terminal to
operate the microprocessor. The ecm also provides this power to the sensors
through the vc output
circuit.
When the vc circuit is short-circuited, the microprocessor in the ...
