R R R  (b) Disconnect the harnesses HJ9 (channel A) and HJ10 (channel B) from the ECU (4000KS) and visually examine the receptacles and the connectors for damaged pins or contamination (Ref. AMM TASK 73-21-50-210-001).
 1_ If damage is found: - repair or replace as required.
R R  2_  If no damage is found:- do an electrical resistance test through each harness HJ9 and HJ10 between: . pin 11 and pin 12 (15 to 60 ohms) . pin 11 and pin 3 (>10 megohms) . pin 11 and the ground (>10 megohms).

R R R  a_ If the resistance values are in the specified limits: - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001), - repeat the fault confirmation given in Para.3.A if the fault continues. 
R R R  b_  If the resistance values are out of the specified limits:- replace the harness with the resistance values out of the limits: . harness HJ9 (Ref. AMM TASK 73-21-50-000-042) and (Ref. AMM TASK 73-21-50-400-042), . harness HJ10 (Ref. AMM TASK 73-21-50-000-043) and (Ref. AMM TASK 73-21-50-400-043).
 B. Do the test given in Para. 3.A.
 (1) No additional maintenance action is required if the fault is not confirmed.
 (2) Repeat the fault isolation procedure if the fault continues.

 3. Fault Confirmation
__________________

 A. Do the operational test of the FADEC 2A 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).
