- replace the COCKPIT SYST.CONTROL. (24MQ).
B. If the FAULT lamp of the indication light 22MQ at the COCKPIT DOOR panel 119VU and STRIKE MID LED at the CKPT CONT panel 20VU are on:
- replace the ELECTRICAL STRIKE CTR. (31MQ) (Ref. AMM TASK 52-51-12-000-001) and (Ref. AMM TASK 52-51-12-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the center release strike 31MQ 2/B to A/N COCKPIT SYST.CONTROL. (24MQ) (Ref. ASM 52-51/01).
(2) If the fault continues:
- replace the COCKPIT SYST.CONTROL. (24MQ).
C. If the FAULT lamp of the indication light 22MQ at the COCKPIT DOOR panel 119VU and STRIKE BOT LED at the CKPT CONT panel 20VU are on:
- replace the ELECTRICAL STRIKE (32MQ) (Ref. AMM TASK 52-51-12-000-001) and (Ref. AMM TASK 52-51-12-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the lower release strike 32MQ 2/B to A/U COCKPIT SYST.CONTROL. (24MQ) (Ref. ASM 52-51/01).
(2) If the fault continues:
- replace the COCKPIT SYST.CONTROL. (24MQ).
D. If the FAULT lamp of the indication light 22MQ at the COCKPIT DOOR panel 119VU and the CHAN 1 LED at the CKPT CONT panel 20VU are on:
- replace the COCKPIT SYST.CONTROL. (24MQ) (Ref. AMM TASK 52-51-14-000-001) and (Ref. AMM TASK 52-51-14-400-001).
E. If the FAULT lamp of the indication light 22MQ at the COCKPIT DOOR panel 119VU and the CHAN 2 LED at the CKPT CONT panel 20VU are on:
- replace the COCKPIT SYST.CONTROL. (24MQ) (Ref. AMM TASK 52-51-14-000-001) and (Ref. AMM TASK 52-51-14-400-001).
F. Do the test given in para. 3.

R **ON A/C 001-049, 051-099, 101-105, 151-199, 201-214,
A. If the buzzer at the cockpit ceiling panel 211HC does not come on:
- enter the emergency entry code and make sure that the green LED at the KEYPAD (25MQ) flashes.
(1) If the green LED at the KEYPAD (25MQ) flashes:
- do a check of 28 VDC at the BUZZER (23MQ).
(a) If there is no 28 VDC:
- do a check for continuity between the BUZZER (23MQ) and the CB(1MQ) (Ref. ASM 52-51/01).
