ATEC Operation.

(1)

The "CHECK TRANS" and "DO NOT SHIFT" lights will come ON when the ENGINE switch is first

turned ON as a bulb and system check. If lights remain ON when truck is started and/or placed into gear,

a failure has been detected. The ATEC ECU for the transmission will place a code into memory.

(c)

Note the arrow symbols in the DDR display. They remind you to use the UP and DOWN arrow

keys to scroll to the desired transmission type. Each touch will move the display up or down by one

item. If you hold an arrow key down, the display will scroll quickly. The list is circular; it will

return to the beginning after the last one is viewed.

(d)

When you see the C(L)(B)T 700 on the bottom line, press the ENTER key. The DDR now begins to

display data. Refer to Step (4) (Data display).

(3)

Non-volatile memory. The ATEC cartridge has a non-volatile memory. This means that stored data are

not lost when the DDR is disconnected from the truck power source.

NOTE

When the DDR establishes communication with the ATEC ECU in a truck, the DDR

memory buffers are all cleared. You cannot use a truck's DDL connector to power your

DDR to review recorded data. The recorded data will be lost.

(a)

When the DDR is connected to an external power source, for instance, at your workbench, the DDR

recognizes that it is not communicating with an ATEC ECU. Under these conditions, the FUNC key

is active. You can access stored data for review and printing. These include ATEC ECU operating

data, diagnostic codes and snapshot data. For example, suppose you have used the DDR to store

snapshot data during a road test. Later, using your workbench power supply, you can review the

recorded data.
