Flashing ATEC codes. ATEC codes are shown in Table 2-15. ATEC troubleshooting procedures are

designed to be performed with the DDR. In situations where a DDR is not available, ATEC codes can be

read by flashing them on the "TRANS CHECK" light. If "TRANS CHECK" light does not flash, no

faults have been detected by ATEC since the last time the codes were cleared. For example, codes 13

and 23 will be flashed as follows:

(a)

Turn OFF ENGINE switch (TM 9-2320-364-10).

(b)

Place a jumperwire between terminals A and B on DDL connector MC13.

(c)

Start engine, observe the "TRANS CHECK" light and record the codes being flashed.

(d)

The "TRANS CHECK" light will flash once for the one in the number 13 and pause for about a half

of a second.

(e)

Then the "TRANS CHECK" light will flash three times for the three in the number 13 and pause for

about three seconds.

(f)

After the three second pause, the "TRANS CHECK" light will flash two times for the two in the

number 23 and pause for about a half of a second.

(g)

After the half second pause, the "TRANS CHECK" light will flash three times for the three in the

number 23.
