MONITOR STATUS
Press 7 to select <MONITOR STATUS> from the < DIAGNOSTIC>. The <MONITOR
STATUS> mode allows you to display the status of the vehicle's on-board monitors, which
monitor the operation of the emissions-related components. These monitors must run in
order for the DTC and test result displays to accurately reflect the condition of the
vehicle's emissions-related components.
The first three display items indicate the systems or components which are continuously
monitored. If the Tester displays N/A (Not Available), the vehicle is not capable of
continuously monitoring that system.
• Misfire monitoring
• Fuel system monitoring
• Comprehensive component monitoring
The other eight display items indicate the status of the tests which are performed “once per
trip”:
• Catalyst monitoring
• Heated catalyst monitoring
• Evaporative system monitoring
• Secondary air system monitoring
• A/C system refrigerant monitoring
• Oxygen sensor monitoring
• Oxygen sensor heater monitoring
• EGR system monitoring
The systems or components listed above can be Completed (COMPL), Not Completed
(INCMPL), or Not Available (N/A).
