Vehicle Diagnostics Glossary

 

Active (Fault)

 

If a fault is active, the reported condition still exists on the vehicle.

 

Airing Event

 

If a trailer is equipped with a supported PSI tire inflation system and is enabled for Trailer Tire Inflation Alerts (TTIA), the system automatically inflates the tire when it detects low pressure. This is called airing or an airing event.

 

Cautionary Tire Pressure Alert

 

A Cautionary tire pressure alert indicates that the MCP has detected a pressure alert from the TPM sensor. The threshold values defining a cautionary (vs. critical) alert are determined by the third-party TPM equipment. These values and how they are set may vary from one manufacturer to another.

 

Critical Tire Pressure Alert

 

A Critical tire pressure alert indicates that the MCP has detected a pressure alert from the TPM sensor. The threshold values defining a critical (vs. cautionary) alert, are determined by the third-party TPM equipment. These values and how they are set may vary from one manufacturer to another.

 

Condition (Fault)

 

The condition on the vehicle responsible for generating a fault.

 

Exception Count (TPM)

 

The number of tires on the vehicle reporting a cautionary or critical status.

 

FM or FMI

 

Failure Mode (Indicator). A value that provides information about the specific fault that occurred. If you need to troubleshoot your fault monitoring alerts, a technician may ask for this number.

 

Make/Model (Vehicle Make/Model)

 

The Vehicle's make (manufacturer, model) as it was entered when the vehicle was configured for the Services Portal.

 

Not Reporting (Tire Pressure Alert)

 

In the context of the Tire Pressure, not reporting means the vehicles in question have reported no tire pressure data for the time period specified.

 

Odometer/As of

 

The vehicle's odometer reading as of the date and time indicated.

 

Overall Status (Tires)

 

The overall status of the vehicle's tires is equal to the status of the worst tire on the vehicle. For example, if one or more tires are critical, the overall status is critical. If one or more tires are cautionary, but no tires are critical, the overall status is cautionary.

 

SPN

 

Suspect Parameter Number. A unique ID associated with a fault type. If you need to troubleshoot your fault monitoring alerts, a technician may ask for this number.

 

Report Reason (Tire Pressure Monitoring)

 

The mobile unit can send a tire pressure report for several reasons. Depending on the mobile unit's configuration, it may send a report upon Ignition On/Off, State Change, or at specified intervals (Periodic).

 

Total Engine Time

 

The number of hours the engine has run as reported by the ECM.

 

Status (Faults)

 

In Fault Monitoring, a fault's status can be either Open or Closed. Open means the fault requires further action. Closed means you have viewed the fault and taken any appropriate actions.

 

Unit Address (UA)

 

A number that uniquely identifies the mobile unit installed on the vehicle. It is sometimes called the serial number

 

Vehicle ID

 

The ID you assigned to the vehicle when you configured it for the Services Portal. If you did not assign an ID, the Vehicle ID is the same as the UA.

 

Vehicle Identification Number (VIN)

 

The Vehicle Identification Number (VIN) as it was entered when the vehicle was configured for the Services Portal.

 

Vendor (Tire Pressure Monitoring)

 

The vendor who manufactured the tire pressure equipment that initiated the tire pressure event. If the equipment does not report a manufacturer name, the vendor shown is Doran/Other. (The Doran equipment does not report the vendor name, so the system assumes the equipment is from Doran if no name is reported.)
