(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.

NOTE

You must be viewing the data list before you can freeze an item.

For the purposes of freezing data, the four lines in the readout display are numbered 1 through

4 from the top. Use the UP and DOWN arrow keys to scroll the data list. When an item you

want to freeze is visible (on any readout line), press the numerical key that corresponds to the

readout line of that item. A solid black square appears next to the item. In the following

example, suppose you want to freeze OIL TEMP. To do so, press numerical key 3 because

OIL TEMP is displayed on line 3.
