ICE
(Caution)

ICE appears when the Left or Right Bleed Management Controller (BMC) indicates that ice is detected with the Anti-ice System OFF.

ICE (Cyan) = ice is detected with anti-ice system is on.
ICE (Amber) = ice is detected with anti-ice system off.

• Ice Detector 1 (E48)
• Ice Detector 2 (E49)
• Left Bleed Management Controller (BMC) (A69)
• Right Bleed Management Controller (BMC) (A70)
• Associated Wiring

1. The following step must be performed while the aircraft is on the ground and while the ICE CAS message is displayed on the EICAS.
2. On the copilot side Cockpit Circuit Breaker Panel (CCBP):

   1. Pull the circuit breaker for one of the ice detectors when you get an amber ICE (Amber/Caution) message when you know there is no icing. Pull one CB at a time to isolate either side then reset prior to pulling other side.
   2. You will get an ICE DETECTOR FAULT (Cyan/Advisory) to tell you have lost redundancy.
   3. If you have pulled the circuit breaker on the ice detector that is giving false indications, then you will lose the ICE message & only the ICE DETECTOR FAULT message will post.

      1. Replace the respective Ice Detector and do close out.

   4. If you pulled the C/B on the ice detector that is serviceable, then you will continue to get the ICE & ICE DETECTOR FAULT message.

3. Interchange the L BMC and the R BMC. Repeat test at step 2.

   1. If the result of the test in step 2 is exactly the same, continue with next step.
   2. If the result of the test is now opposite from the first time it was performed, replace the original R BMC and do close out.

4. Perform a wiring check between the Ice Detector 2 and the right BMC as follows:
   

   From	To	Result
   E49P1-8	A70P2-26

   1. If wiring defects are found, repair defective wiring as required and do close out.
   2. If no defects are found, replace Ice Detector 2 and do close out.

5. Interchange the L BMC and the R BMC. Repeat test at step 2.

   1. If the result of the test in step 2 is exactly the same, continue with next step.
   2. If the result of the test is now opposite from the first time it was performed, replace the original L BMC and do close out.

6. Perform a wiring check between the Ice Detector 1 and the L BMC as follows:
   

   From	To	Result
   E48P1-8	A69P2-26

   1. If wiring defects are found, repair defective wiring as required and do close out.
   2. If no defects are found, replace Ice Detector 1 and do close out.

7. Do close out.
