 A. Test
 (1) Do the operational test of the FADEC 1B on the ground (with engine non motoring) (Ref. AMM TASK 73-29-00-710-040).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message T5 SNSR, J13, ECU or T5 SNSR, J13, ECU*:
 - do a check for open or short to ground of the harness HJ13 between the ECU (4000KS) and the 6 o'clock junction box, between the 6 o'clock junction box and the T5 sensor (Ref. ASM 73-25/18).
 (1) If the wiring is not correct:
 - repair the above wiring.

 - disconnect the harness HJ13 from the ECU (4000KS) and do a resistance check of the cable J13 between: . pins 11 and 23 (0.5 to 10 ohms) . pins 11 and 24 ( > to megohms) . pin 11 and the ground ( > 10 megohms).
 (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).

 (b) If the resistance values are out of the specified limits:

 - disconnect the connector CJ13 at the 6 o'clock junction box and do a resistance check of the cable CJ13 between: . pins 2 and 11 (0.5 to 10 ohms) . pins 2 and 12 ( > 10 megohms) . pin 2 and the ground ( > 10 megohms) (Ref. AWM 71-51-09).
 1 If the resistance values are in the specified limits:
_
 - replace the harness HJ13 (Ref. AMM TASK 73-21-50-000-046) and (Ref. AMM TASK 73-21-50-400-046).
 2 If the resistance values are out of the specified limits:
_
 - disconnect the harness CJ13 from the T5 sensor and do a resistance check of the T5 sensor between: . pins A and B (0.88 to 1.22 ohms) . pin A and the ground ( > 10 megohms).
 a If the resistance values are in the specified limits:
_
 - replace the harness CJ13 (Ref. AMM TASK 73-21-50-000-029) and (Ref. AMM TASK 73-21-50-400-029).
 b If the resistance values are out of the specified limits:
_
 - replace the T5 temperature sensor (Ref. AMM TASK 77-22-10-000-002) and (Ref. AMM TASK 77-22-10-400-002).
 B. Do the test given in Para. 3.A.
