R  E. If the LCIT is more than 10 deg.C higher than the outside air temperature 
R  (TAT): 
R  - check for hot gas ingestion (make sure that the main engine exhaust is 
R  not blown into the APU air intake), 
R  - check for hot gas leaks at the APU compressor split lines. 
R  (1) If the fault appears to be intermitted: 
R  - do a check and repair of the aircraft wiring 
R  from the ECB (59KD) AB/H3,H4 to the electrical connector P1/7,6 
R  and 
R  from P1/7,6 to the Inlet Temp Sensor P6/B,A 
R  (Ref. ASM 49-61/02) 
R  - replace the INLET TEMP SENSOR (8010KM) (Ref. AMM TASK 49-23-14-000-
R  001) and (Ref. AMM TASK 49-23-14-400-001). 
R  (a) If the fault continues: 
R  - replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and 
R  (Ref. AMM TASK 49-61-34-400-001). 
R  F. If the LCIT is more than 10 deg.C lower than the outside air temperature 
R  (TAT): 
R  - do a check and repair of the aircraft wiring 
R  from the ECB (59KD) AB/H3,H4 to the electrical connector P1/7,6 
R  and 
R  from P1/7,6 to the Inlet Temp Sensor P6/B,A 
R  (Ref. ASM 49-61/02) 
R  - replace the INLET TEMP SENSOR (8010KM) (Ref. AMM TASK 49-23-14-000-001) 
R  and (Ref. AMM TASK 49-23-14-400-001). 
R  (1) If the fault continues: 
R  - replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. 
R  AMM TASK 49-61-34-400-001). 
R  (a) If the fault continues: 
R  - do a check and repair of the aircraft wiring from the ECB 
R  (59KD) AB/4H,3H to the INLET TEMP SENSOR studs/alumel,chromel 
R  (Ref. ASM 49-62/02) (Ref. ASM 49-62/04). 
R  **ON A/C 001-049, 101-105, 107-107, 151-199, 201-210, 

R G. If:
R .the bleed pressure is low with one engine in MIN IDLE operation, to
R supply back pressure on ENG.
R .the APU self test gives no maintenance message.

R  NOTE : On the APU page of the lower ECAM display unit, the BLEED (PSI)____ 
R  value is within 8 psig. 
R  NOTE : Aircraft configuration:____ 
R  - the PACK 1 and 2 p/bsw are OFF, 
R  - the APU BLEED valve p/bsw is ON, 
R  - do one MES at a time. 
R  - isolate the left or right engine. 
R  (1) For the related engine: 
R  - do the trouble shooting of the engine STARTER SHUTOFF VALVE (SAV). 
R  (a) If the fault continues: 
R  - do the operational test of the BMCs (Ref. AMM TASK 36-11-00-
R  740-001). 
R  1_  If the test gives a maintenance message:
R  - do the related trouble shooting procedure. 
R  2_  If the test is OK:
R  - do a leak check of the aircraft bleed system. 
R  H. If: 

R .the bleed pressure has large fluctuation of +/- 20 psig with both packs
R in operation.
R .the APU self test gives no maintenance message.

R NOTE : If one pack is operating, the external temperature and the cabin

____ R temperature are high, APU bleed-pressure fluctuation occurs when R you start the second pack to decrease the cabin temperature. R This bleed pressure fluctuation is a normal effect after the start R of the two pack operation in maximum cooling mode until the cabin R temperature has decreased sufficiently after some time.
R - replace the PACK-FLOW CONTROL VALVE (8HB) and/or PACK-FLOW CONTROL
R VALVE (11HB)
R (Ref. AMM TASK 21-51-51-000-001) and (Ref. AMM TASK 21-51-51-400-001).

R (1) If the fault continues:
R - do a check for blockade of the Pack Heat Exchanger(s).
R Replace/Clean as necessary
R (Ref. AMM TASK 21-52-24-000-001) and (Ref. AMM TASK 21-52-24-400-R 001).

R J. Do the test given in para. 3.
