A. Do the Bite Test of the Heated Floor Panel System (Ref. AMM TASK 25-27-00-740-001).
4. Fault Isolation
_______________
A. If one test indicator on the related control unit does not come on:
- Do a check of the related fuse. If it is necessary replace the related fuse.
(1) If the fuse is not serviceable:
- Do a check of the aircraft wiring for a short circuit between the related control unit and the inoperative heated floor panel (Ref. ASM 25-27/01) or (Ref. ASM 25-27/02).
(a) If there is a short to ground:
- Repair the aircraft wiring (Ref. ASM 25-27/01) or (Ref. ASM 25-27/02).

(b) If there is no short to ground:
- Replace the related control unit (Ref. AMM TASK 25-27-34-000-002) and (Ref. AMM TASK 25-27-34-400-002).
(c) If the fault continues:
- Replace the related heated floor panel (Ref. AMM TASK 25-27-51-000-002) and (Ref. AMM TASK 25-27-51-400-002).
(2) If the fuse is serviceable:
- Do a check of the aircraft wiring between the related control unit and the inoperative heated floor panel (Ref. ASM 25-27/01) or (Ref. ASM 25-27/02).
(a) If there is continuity:
- Replace the related control unit (Ref. AMM TASK 25-27-34-000-002) and (Ref. AMM TASK 25-27-34-400-002).
(b) If there is no continuity:
1_ If the fault continues:
- Replace the related heated floor panel (Ref. AMM TASK 25-27-
51-000-002) and (Ref. AMM TASK 25-27-51-400-002).
- Repair the aircraft wiring (Ref. ASM 25-27/01) or (Ref. ASM 25-27/02).
B. Do the test given in para. 3.A.
