Data Readout Window

Use the UP and DOWN arrow keys to scroll through the entire data list. Pressing a key causes the

display to move one line. Holding a key causes the display to scroll quickly. Pressing the LEFT

arrow key causes the display to advance four lines. Pressing the RIGHT arrow key causes the

display to move backward four lines. When you reach the end of the list, you will see the display

that tells you which system you are testing.

NOTE

Parameters in the data list that do not pertain to the system you are testing will be

designated by NA, meaning not available.

For an explanation of each of the items in the data list, refer to Steps (12) through (31) of this

section.

(b)

What to do with NO DATA Readout. If you get the NO DATA message, there are several things to

check:

Bad connection - Check the truck cable at each terminal for a good connection. In an extreme

case, a wire may be broken in the truck cable or in the ATEC ECU wiring.

Engine ON OFF switch - Be sure the ENGINE switch is ON.

Bad ATEC ECU, or blown ATEC ECU fuse - If the ATEC ECU is incapable of transmitting data,

the DDR will not receive any.

(c)

Data freeze operation.

There are times when you want to be able to quickly view several operating parameters at the

same time, even though they are not normally together in the data list. One way to do this is to

create a custom data list using the Custom Data List function. Another way is to use the Data

Freeze function.

NOTE

There are two differences between Custom Data List and Data Freeze. In Custom

Data, you can scroll the entire reorganized data list exactly like the normal data

list. In Data Freeze, the items you "freeze" cannot be scrolled. The rest of the list

scrolls normally. Also, you can use a custom list, but not a data freeze, when using

Snapshot.

To freeze a line of data, follow Steps 3 through 5.
