On-Board System Readiness Test

ON-BOARD SYSTEM READINESS TEST

Description
All OBD scan tools should display the On-Board System Readiness (OSR) Test. The OSR will display the supported monitors on the vehicle, the status of all monitors (complete or not complete and the MIL status. If a monitor is not complete, the scan tool will not identify the monitor that has not completed. Readiness for the 6.0L is reported based on the completeness of the comprehensive component monitors (CCM) and the misfire monitor and the EGR monitor. These monitors must be complete before readiness can be cleared. It is not possible to determine which individual monitors are complete/incomplete.

Accessing On-Board System Readiness Test
- Refer to the manufacturer manual for scan tool instructions.

OBD PID Data Monitor
The PID monitor for OBD offers real time evaluation of several emissions-related parameters. Most of these are related to the HO2S for which the diesel has no equivalent. The only parameters which apply to 6.0L diesel applications are DTC CNT, IAT, LOAD, MAP, MIL, RPM and VSS.

Accessing the PID Data Monitor
- Refer to the manufacturer manual for scan tool instructions.

OBD Pending DTCs
Pending DTCs are DTCs that have only set during one drive cycle and may not have set the MIL yet. These DTCs may be identified using the Retrieve Pending DTCs Feature. Additionally, they will be found in the vehicle-specific mode RETRIEVE/CLEAR CONTINUOUS MEMORY DTCs from the instant that the DTC is set.

This function will only report pending failures that have occurred during the present drive cycle, but not indicate single failures that happened on any previous drive cycle.

Accessing the PID Data Monitor
- Refer to the manufacturer manual for scan tool instructions.

Misfire Monitoring Supported
This menu pick can be used to determine if the misfire monitoring system is supported on your particular application. All emission-equipped 6.0L diesel vehicles under 14,000 lbs utilize misfire detection. When selecting this function, a message will be displayed on the screen: "test not supported by this module" or "test supported by this module".

Comprehensive Component Monitoring Supported
This menu pick can be used to determine if the comprehensive component monitoring system is supported on your particular application. All emission-equipped 6.0L diesel vehicles under 14,000 lbs utilize comprehensive component monitoring. When selecting this function, a message will be displayed on the screen: "test not supported by this module" or "test supported by this module".

Misfire Monitoring Status
This menu pick can be used to determine the status of the misfire monitoring system on your particular application. All emission-equipped 6.0L diesel vehicles under 14,000 lbs utilize misfire detection. When selecting this function, a message will be displayed on the screen: "test complete or not applicable" or "test not complete."

Comprehensive Component Monitoring Status
This menu pick can be used to determine the status of the comprehensive component monitoring system on your particular application. All emission-equipped 6.0L diesel vehicles under 14,000 lbs utilize comprehensive component monitoring. When selecting this function, a message will be displayed on the screen: "test complete, or not applicable" or "test not complete."

PTO Status
This menu pick can be used to determine the status of the PTO system on your particular application. Some transmission OBD monitors are disabled during PTO operation. Vehicle must be out of PTO mode to clear P1000. When selecting this function, a message will be displayed on the screen: "PTO active" or "PTO non active."
