Section 4 – Global OBD II Diagnostics

The first time the scan tool communicates with the vehicle, the communication type is automatically detected, and is used until the scan tool is turned OFF or another vehicle is diagnosed.

✓If an Error Message displays, make sure the OBD II connector is securely attached, and the ignition key is ON. Cycle the ignition key to OFF for 10 seconds, then ON. This may be required to reset the computer. If required, select YES to try again. If the problem still exists, refer to “Error Messages” on page 8-2.

MANUAL INFO

The Manual Info function, the last one in the function list, instructs the user what section of the manual to use. This section covers Global OBD II Diagnostics.

I/M READINESS

4

The I/M Readiness (Inspection and Maintenance) function displays the state of the vehicle’s OBD II Monitors. Monitors are tests designed to verify the oper- ation of emission related systems or components and detect out-of-range val- ues. The vehicle may have to be operated under certain driving conditions to initiate a monitor. If the vehicle loses electrical power or codes are erased, the monitors may be cleared. This function can be performed with the key ON — engine OFF (KOEO) or key ON — engine Running (KOER).

The abbreviations and names for the OBD II Monitors supported by this tool are shown in the following list. They are required by the U.S. Environmental Pro- tection Agency (EPA). Not all monitors are supported by all vehicles.

Abbreviated Name	Expanded Name
Misfire Monitor	Misfire Monitor
Fuel System Mon	Fuel System Monitor
Com Component	Comprehensive Components Monitor
Catalyst Mon	Catalyst Monitor
Htd Catalyst	Heated Catalyst Monitor
Evap System Mon	Evaporative System Monitor
Sec Air System	Secondary Air System Monitor
A/C Refrig Mon	Air Conditioning Refrigerant Monitor
Oxygen Sens Mon	Oxygen Sensor Monitor

EGR System Mon	Exhaust Gas Recirculation System Monitor

The vehicle may support two types of I/M Readiness:

❒SINCE DTCs CLEARED shows the status of the monitors since the DTCs were last erased.

❒THIS DRIVING CYCLE shows the status of the monitors since the start of the current drive cycle.

If the monitors are not supported for THIS DRIVING CYCLE, then the scan tool only shows monitors for SINCE DTCs CLEARED with no header on line 1.
