75-24-00-810-801 - Failure of the Active Clearance Control-Actuator on Engine 1 For training purpose only NOTE: Multiple Dual Track Check Faults may indicate a failed fuel pump. Four control units on the engine are driven by HP fuel: the VSV actuator, the 2.5 Bleed Controller, the ACOC Air Modulating Valve and the Active Clearance Control Actuator. If you have faults with two or more of these units, you must follow the Multiple Dual Track Check Faults procedure (Ref. TSM TASK 73-00-00-810-900) . (1) Energize the aircraft electrical circuits AMM TASK 24-41-00-861-002 . (2) On the panel 50VU, release the ENG FADEC GND PWR 1 and 2 pushbutton switches. B. FADEC Ground Test (1) Do the CFDS Message Decoding and read the Scheduled Maintenance Report (Ref. TSM TSM 70-00-00 P.Block 301) . (2) If the readout gives one of the following fault codes in FADEC 1A or FADEC 1B (Fault Acronym: HCCWAF): - do the FADEC Ground Test AMM TASK 73-22-00-710-040 for fault confirmation. - continue with Fault Isolation Para 4. (3) If the fault code readout in (1) does not give one of the above listed fault codes: - continue with fault confirmation by Engine Ground Run Section 4.B below. C. Test (1) On the panel 50VU, push the ENG FADEC GND PWR 1 pushbutton switch and release it again. NOTE: This action resets the FADEC memory. (2) Do the test No. 11: high power assurance test AMM TASK 71-00-00-710-013 . (3) Read the LAST LEG REPORT and the scheduled maintenance report of the FADEC (1A and 1B) menu on the MCDU (Ref. TSM TSM 70-00-00 P.Block 301) and make a record of the maintenance message and the fault code for the applicable fault cells. 4. Fault Isolation (Ref. Fig. 201/TASK 75-24-00-991-001 SHEET 201.1) A. If the test gives the maintenance message ACC ACT/HC/EEC1: - open the thrust reverser halves 451AL and 452AR AMM TASK 78-32-00-010-010 - examine the harness AMM TASK 71-50-00-210-010 from the EEC (4000KS) to the ACC actuator (4027KS) ASM 73-25/18 . (1) If the fault continues: - disconnect the connector from the ACC actuator - examine the connector and receptacle AMM TASK 71-50-00-210-010 - connect the connector to the ACC actuator AMM TASK 70-23-15-912-010 . (2) If the fault continues: - read the fault code shown on the FLIGHT DATA and GROUND DATA of the FADEC (1A and 1B) menu on the MCDU (Ref. TSM TSM 70-00-00 P.Block 301) - make a record of the fault code. (a) If the FADEC 1A menu gives the fault code HCCL: - disconnect the electrical harness connector (4000KS-J2) from the EEC (4000KS) - examine the connector and the receptacle at the electrical connector (4000KS-J2), do a check of the resistance between: . pins P and f (86 to 146 ohms)
