_______________
A. If the test gives a different maintenance message:
- Do the trouble shooting procedure related to the maintenance message.
B. If the test gives the maintenance message SLIDE BOTTLE EXIT R, or DEU-B 300RH4:
- get access to the inflation reservoir (Ref. AMM TASK 25-62-49-000-001),
NOTE : Only use the access procedure.
____
- make sure the gage needle of the inflation reservoir pressure-gage is positioned over the green cursor, or to the right of the green cursor.

NOTE : The green cursor of the pressure gage is temperature compensated,
____ and reacts to temperature changes faster than the gas expansion in the inflation reservoir. The green cursor moves independently of the pointer when a temperature change occurs.
(1) If the pressure indication is not correct:
- replace the PRESSURE BOTTLE DOOR 3RH (7777MM), (Ref. AMM TASK 25-62-49-000-001) and (Ref. AMM TASK 25-62-49-400-001).
(2) If the pressure indication is correct:
- replace the DEU-B (300RH4), (Ref. AMM TASK 23-73-47-000-001) and (Ref. AMM TASK 23-73-47-400-001).
(3) If the fault continues:
- do a check and repair the wiring between the: DEU-B (300RH4) connector C/37 and the SLIDE BOTTLE PRESS SENSOR connector A/A (Ref. ASM 25-65/01) and (Ref. ASM 23-73/11).
- close access to the inflation reservoir (Ref. AMM TASK 25-62-49-400-001).
NOTE : Only use the close-up procedure.
____
C. Do the test as given in paragraph 3. A. to check the correct operation (no maintenance message is shown).
