Monitor Description

Description of what the motor generator control ECU monitors and how to detects malfunctions (monitoring purpose and its details).

Related DTCs

A group of diagnostic trouble codes that are output by the motor generator control ECU based on the same malfunction detection logic.

Typical Enabling Conditions

Preconditions that allow the motor generator control ECU to detect malfunctions.

With all preconditions satisfied, the motor generator control ECU stores DTCs when the monitored value(s) exceeds malfunction threshold(s).

Sequence of Operation

Order of monitor priority, applied if multiple sensors and components are involved in a single malfunction detection process.

Each sensor and component are monitored in turn and subsequent items are not monitored until the previous detection operation completes.

Required Sensors/Components

Sensors and components used by the motor generator control ECU to detect each malfunction.

Frequency of Operation

Number of times the motor generator control ECU checks for each malfunction during each driving cycle.

"Once per driving cycle" means that the motor generator control ECU only checks for malfunctions once during a single driving cycle.

"Continuous" means that the motor generator control ECU checks for malfunctions whenever enabling conditions are met.

Duration

Minimum time for which the motor generator control ECU must detect continuous deviation in monitored value(s) in order to store a DTC. Timing begins when typical enabling conditions are met.

Malfunction Thresholds

Value beyond which the motor generator control ECU determines malfunctions exist and stores DTCs.

MIL Operation

Timing of MIL illumination after a malfunction is detected.

"Immediate" means that the motor generator control ECU illuminates the MIL as soon as a malfunction is detected.

"2 driving cycles" means that the motor generator control ECU illuminates the MIL if the same malfunction is detected again during the next driving cycle.
