Monitor description |
Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details). |
Related DTCs |
Group of diagnostic trouble codes that are output by the ECM based on the same malfunction detection logic. |
Typical enabling condition |
Preconditions that allow the ECM to detect malfunctions. With all preconditions satisfied, the ECM stores 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 a 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. "Once per driving cycle" means that the ECM detects the malfunction only one time during a single driving cycle. "Continuous" means that the ECM detects the malfunction every time the enabling condition is met. |
Duration |
The minimum time that the ECM must detect a continuous deviation in the monitored value(s) before storing 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 store 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 cycles" 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. |

Generator Signal Circuit
DESCRIPTION
When the engine is started, the generator assembly turns on and a voltage pulse
signal is generated.
This signal is used by the air conditioning amplifier assembly.
The signal expressing the amount of output from the generator assembly is one ...
