R NOTE : This fault will be set if a DAC ID plug is installed on a SAC
____ R engine. The engine nameplate and ID plug can be checked on the R MCDU screen. Acces reporting functions, then select the LRU R Identification Screen. Line 4 of the LRU Identification Screen R will display. R - "EGT MON" or "SAC CONFIG" for a SAC ID plug R - "DAC CONFIG" for a DAC ID plug
R (2) If the nameplate is for a DAC engine:
R - Disconnect the HJ11 harness from the ECU (4000KS)
R - Do a resistance check of the HJ11 harness between (Ref. ASM 73-R 25/18):
R . pins 4 and 5 (72 to 89 ohms)
R . pins 6 and 7 (42 to 52 ohms)
R . pins 2 and 3 (42 to 52 ohms)
R . pins 4 and 1 (more than 10 megohms)
R . pins 6 and 1 (more than 10 megohms)
R . pins 2 and 1 (more than 10 megohms)
R . pin 4 and the ground (more than 10 megohms)
R . pin 6 and the ground (more than 10 megohms)
R . pin 2 and the ground (more than 10 megohms)
R (a) If the resistance values are out of the specified limits: R - Disconnect the HJ11 harness from the cable CJ11R at the 6 R o'clock junction box R - Do a resistance check of the cable CJ11R between (Ref. ASM 73-R 25/18).
R . pins 20 and 21 (72 to 89 ohms)
R . pins 7 and 19 (42 to 52 ohms)
R . pins 2 and 9 (42 to 52 ohms)
R . pins 20 and 8 (more than 10 megohms)
R . pins 7 and 8 (more than 10 megohms)
R . pins 2 and 8 (more than 10 megohms)
R . pin 20 and the ground (more than 10 megohms)
R . pin 7 and the ground (more than 10 megohms)
R . pin 2 and the ground (more than 10 megohms)
R 1_ If the resistance value are in the specified limits:
R - replace the HJ11 harness (Ref. AMM TASK 73-21-50-000-044)
R (Ref. AMM TASK 73-21-50-400-044).
R 2_ If the resistance value are out of the specified limits:
R - Disconnect the harness CJ11R from the BSV valve.
R - Do a resistance check at the BSV valve between (Ref. ASM 73-R 25/18).
R . pins 4 and 2 (72 to 89 ohms)
R . pins 6 and 7 (42 to 52 ohms)
R . pins 8 and 9 (42 to 52 ohms)
R . pins 2 and 1 (more than 10 megohms)
R . pins 6 and 1 (more than 10 megohms)
R . pins 8 and 1 (more than 10 megohms)
R . pin 2 and the ground (more than 10 megohms)

R a_ If the resistance values are in the specified limits:
R - replace the CJ11R harness (Ref. AMM TASK 73-21-50-000-
R 026) (Ref. AMM TASK 73-21-50-400-026).
R b_ If the resistance values are out of the specified limits:
R - replace the BSV (Ref. AMM TASK 73-11-70-000-002) (Ref.
R AMM TASK 73-11-70-400-002).
R (b) If the resistance values are in the specified limits:
R - replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) (Ref.
R AMM TASK 73-21-60-400-001)
R B. Do the test given in Para. 3.A.
