(a) Make sure that the circuit breaker (2DL) is closed (Ref. ASM 30-11/01).
(b) Do the test in Para. 3.A.
- if the fault continues, do the next step.
(2) Do a check of the C/B ANTI ICE/WING/CTL (2DL).
(a) If the check is unsatisfactory, replace the circuit breaker (2DL).
(b) Do the fault confirmation in Para. 3.A.
- if the fault continues, do the next step.
(3) Do a check of the Diode 1160VD.
(a) If the check is unsatisfactory, replace the diode.
(b) Do the fault confirmation in Para. 3.A.
