In–2 – Introduction General Information Legend Definition of terms Each monitor description follows a standardized format using these terms: In009–01 IMPORTANT CHANGE NOTICE: Information not applicable to the 2000 Lexus LX470 was deleted to reduce the size of this document. As a result some pages are deliberately missing 1996–2003 ADDITION OF OBD (OTH021U) 2 Author : Date: Terminology Definition Duration Once the ”Enabling Conditions” are satisfied this is the length of time that a moni- tored value exceed threshold limits before the ECM will set a DTC. Frequency of operation The number of times that the ECM runs this monitor per driving cycle.

”Once per driving cycle” means that the ECM detects malfunction only one time during a single driving cycle. ”Continuous” means that the ECM detects malfunction every time the monitored value(s) exceed or deviate from the thresholds during a single driving cycle. Typical Malfunction Thresholds The specified value(s) for a diagnostic test. The ECM will set a DTC when values exceed or below these limits. MIL operation MIL ON timing after a DTC is set. ”Immediate” means that the ECM illuminates MIL the instant the ECM detects a malfunction and sets a DTC. ”2 driving cycle” means that the ECM illuminates the MIL if the same malfunction is detected in the 2nd driving cycle.

Monitor description The method and procedures that the ECM uses to detect malfunctions. Related DTCs This DTC plus other DTCs that are related to this system. Required sensors/components The sensors are used by the ECM to detect malfunctions. Sequence of operation Monitor priority when multiple components or sensors are involved. While another sensor diagnostic is in progress, the next sensor or component will not be monitored until the previous diagnostic is concluded. Typical Enabling Conditions Preconditions that must be met before the ECM will begin a diagnostic test. With all preconditions satisfied, the ECM sets the DTC when a monitored value(s) exceeds the malfunction threshold(s).
