3. Job Set-up
Subtask 73-21-60-861-065-A ** ON A/C NOT FOR ALL

A. Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).

Subtask 73-21-60-869-067-A ** ON A/C NOT FOR ALL

B. Preparation for test
(1) On the overhead maintenance panel 50VU, push then release the ENG/FADEC GND PWR/1(2) pushbutton switch. The ON legend comes on.
(2) On the left or right MCDU get the SYSTEM REPORT/TEST ENG page (Ref. AMM TASK 31-32-00-860-012).

4. Procedure
Subtask 73-21-60-740-060-A ** ON A/C NOT FOR ALL

A. Do this procedure for the ECU 1(2) channel A.

NOTE: This test is for the system 1. For the other system(s), use the indications between the parentheses.

ACTION	RESULT
1.On the MCDU:
Push the line key adjacent to the FADEC 1A (2A) indication.	The ENGINE 1(2) MAIN MENU page comes into view.
2.Push the line key adjacent to the SPECIFIC DATA indication.	The SPECEFIC DATA page comes into view.
3.Push the line key adjacent to the PWR SETTING MAX VALUES indication.	The PWR SETTING MAX VALUES page comes into view with the maximum N1, N2 and EGT values related to the last engine operation. Both indicated and physical N1 and EGT values are displayed. NOTE: If the value of one of these parameters is higher than the max limit, the report also shows how long (in seconds) the associated parameter was at that limit. If no overlimit condition occured, there is no time indication. NOTE: You can reset these values if necessary. To do this, push the line key adjacent to the RESET MAX VALUES then CONFIRM RESET indications.

(1) Do this procedure for the ECU 1(2) channel B.
(2) On the MCDU, push the line select key adjacent to the RETURN indication until the CFDS menu page comes into view.
(3) Stop the MCDU.
