Toyota RAV4 (XA40) 2013-2018 Service Manual: Precaution

Notice:

Perform the reset memory procedures (a/t initialization) when replacing the automatic transaxle assembly, engine assembly or ecm (see page ax-18).

Hint:

Reset memory cannot be completed by only reconnecting the cable to the negative (-) battery terminal.

Caution:

When using compressed air, always aim away from yourself to prevent automatic transmission fluid (atf) or kerosene from spraying on your face.

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.

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.

While another sensor is being monitored, the next sensor or component will not be monitored.

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.

"Once per driving cycle" means that the ecm detects malfunction only 1 time during a single driving cycle.

"Continuous" means that the ecm detects a malfunction every time the 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.

"Immediate" means that the ecm illuminates the mil the instant the ecm determines that there is a malfunction.

"2 Driving cycle" means that the ecm illuminates the 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.

Use these ranges as a reference.

They cannot be used to judge if a sensor or solenoid is defective or not.
