(b)
 If no sensing element is damaged:

 -disconnect the connector between the sensing elements 56HF and 55HF
 -connect the LOOP CONTROLLER (9240SI) between the connector 1HA2-AA/5D and the ground
 -do a check of the impedance read on the LOOP CONTROLLER (9240SI).
 1_ If the impedance is less than 3 KOhms:
 - disconnect the connector between the sensing elements 60HF
 and 59HF
 - do a check of the impedance read on the LOOP CONTROLLER
 (9240SI).
