(a) If there is no short circuit connect the electrical connector (17HKA).
(b) If there is a short circuit repair the related wiring between:
- the SENSOR-DUCT TEMPERATURE,AFT CABIN (17HK) to the ZC (8HK).
- connect the electrical connector (17HKA).
(9) If the fault continues:
- disconnect the electrical connector (21HKA) from the SENSOR-TEMPERATURE,COCKPIT (21HK).
- at the electrical connector (21HKA) do a check for a short circuit between pins A and B, D and E and between GND and pins A, B, D and
E.
