 D. Job Set-Up
 (1) On the panel 115VU, make sure that:

 (a) The ENG/MODE/CRANK/AUTO IGN/IGN selector switch is set to NORM.

 (b) The ENG MASTER 2 switch is set to OFF.

 (2) On the panel 22VU, make sure that the ENG/MAN START/2 pushbutton switch is released.

 (3) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).

 E. Test
 (1) On the panel 50VU, release the ENG/FADEC GND PWR/2 pushbutton switch (ON legend on).

_______________
 A. If the test does not show XX on the upper ECAM DU, but shows engine 2 parameters:
 (1) Do a check and repair the wiring between the ENG/MODE/CRANK/AUTO IGN/IGN selector switch (6KS) and the EIU 2 (1KS2), (Ref. ASM 73-25/08).

 (2) If the fault continues:

 - replace the SEL SW-ENG/MODE/CRANK/AUTO IGN/IGN (6KS).

 (3) If the fault continues:

 - replace the EIU-2 (1KS2), (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
 B. If the test does not show engine 2 parameters on the upper ECAM DU, but shows XX:
 (1) Make sure that there is 28VDC at the pin 11 of the connector 1KS2-AC (Ref. ASM 73-25/05).

 (a) If there is no 28VDC:

 - do a check and repair the wiring between the circuit breaker 2KS2 and the EIU 2 (1KS2).

 (b) If there is 28VDC:

 - do a check and repair the wiring between the pin 7 of the connector 1KS2-AC and the pin 13 of the connector 4000KS-J1.
