Engine non Motoring)
AMM 80-11-20-000-003 Removal of the Starter Shutoff Valve
AMM 80-11-20-400-003 Installation of the Starter Shutoff Valve
3. Fault Confirmation
__________________
A. Do the operational test of the FADEC 1A on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. This failure message is generated if channel A and B switches of the R starter shutoff valve disagree.
(1) If the failure message SAV (SW) J9/J10, ECU* is not confirmed: R
R (a) No maintenance action is required.
(2) If the failure message SAV (SW) J9/J10, ECU* is not confirmed but is repetitive:
- replace the starter shutoff valve (Ref. AMM TASK 80-11-20-000-003) and (Ref. AMM TASK 80-11-20-400-003).

R R R (a) If the failure continues during the subsequent flights: - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
R (b) If the failure continues during the subsequent flights: - replace the harness HJ9 (channel A) (Ref. AMM TASK 73-21-50-000-042) and (Ref. AMM TASK 73-21-50-400-042). - replace the harness HJ10 (channel B) (Ref. AMM TASK 73-21-50-000-043) and (Ref. AMM TASK 73-21-50-400-043).
R (3) If the failure message SAV (SW) J9/J10, ECU* is confirmed: - disconnect the harnesses HJ9 (channel A) and HJ10 (channel B) from the starter shutoff valve.
R (a) Visually examine the receptacles and the connectors for damaged pins or contamination (Ref. AMM TASK 73-21-50-210-001).
R 1_ If damage is found: - repair or replace as required.
R R R 2_ If no damage is found:- do an electrical resistance test through the starter shutoff valve for both channels between: . pin 1 and pin 2 (15 to 60 ohms) . pin 1 and pin 5 (> 10 megohms) . pin 1 and the ground (> 10 megohms).
R R R a_ If the resistance values are out of the specified limits:- replace the starter shutoff valve (Ref. AMM TASK 80-11-20-000-003) and (Ref. AMM TASK 80-11-20-400-003).
R R R b_ If the resistance values are in the specified limits:- connect the harnesses HJ9 (channel A) and HJ10 (channel B) to the starter shutoff valve and continue the trouble shooting procedure.
