8 He


Faults: Active and Inactive The FAULTS tab displays the faults codes detected on the vehicle engine module. The fault codes are separated into two lists. The iQ displays the active faults in a list on the left side of the screen and the inactive faults in a list on the right side of the screen.

NOTE:

i If the iQ finds faults from more than one module, it lists the name of the module in the top line of each listed fault. For example, if you are looking at faults with the engine ECU, each fault code is identified in the top line (e.g., Engine #1). The top line of the fault code changes to match the spe-cific module (for example, Engine #2 or Transmission #1) if these modules are present.

Viewing Active Faults

The header of the active faults list displays the number of faults in the list (for example, Active - 12). Use the Up and Down buttons to navigate the list to view all the fault codes found during scanning.

The table below describes the information the iQ provides for each fault code.

Line Number Contents

1 (top, gray) The name of the module where the fault was found (e.g., Engine #1)

2 A short description of the fault (e.g., Intake Manifold Temperature)

3 Parameter information associated with the fault (e.g., Engine Oil Pressure 50.5 psi)

4 (bottom) SAE/DTC information about the fault (e.g., SPN 100 - FMI 4)


- Faults: Active and Inactive

Viewing More Information on Active Faults

The More Info button appears at the bottom left of each fault code in the list.

To view more information about a fault code:

Creating a Quick ListA Quick List is a place for storing parameters from either one or both of the following:

• Different categories (i.e., the categories on the left side of the display)

• Different modules (e.g., Engine 1, Transmission, Brakes)

The Quick List is limited to eight parameters.

For example, while diagnosing a vehicle, you may be interested in a few Engine module parameters and how they relate to a few parameters on the Transmission module. You can add the parameters of interest to the Quick List and view them all at the same time.

NOTE:

i There can only be one Quick List. You may, however, clear the Quick List and create a new one when you need to compare other parameters.

To create a Quick List:

1 Start from the Parameter/Value display.

- Creating a Quick List

2 Click the box in the Add to Quick List column next the parameter you want

to include in the Quick List (e.g., Engine Speed, Fuel Delivery Pressure, and

Injector Metering Rail 1 Pres...).

NOTE:

i You may also select parameters from other categories (e.g., White

Smoke), or from other modules if present (e.g., Transmission or Brakes).

A red checkmark appears to the left of the parameter to indicate that the

parameter has been added to the Quick List.

NOTE:

i The View Quick List button at the top left of the screen displays the

number of items currently in the Quick List.

If you click the View Quick List button and have not previously created a

Quick List, the following screen is displayed.
