No. Result Description Possible Causes/Action
(S27-S29).
2. Replace the BiCU
(PCB1).
• ID sensors (S27-S29)
are dirty:
1. Clean the ID sensors
(S27-S29).

54 ID sensor coefficient
(K5) maximum/
minimum error
When the K5 is more than the
value of SP3-362-003 or less than
the value of SP3-362-004, the error
54 is displayed.
