CAN COMM CIRC 
[U1000]

Malfunction is detected in CAN communication.

CAUTION:

Even when there is no malfunction on CAN communication system, malfunction may be 
misinterpreted when battery has low voltage (when maintaining 7 - 8 V for about 2 sec-
onds) or 10A fuse [No. 19, located in the fuse block (J/B)] is disconnected.

CIRC
[B2205]

When an erroneous speed signal is input for 1 seconds.

CAUTION:

Even when there is no malfunction on speed signal system, malfunction may be misin-
terpreted when battery has low voltage (when maintaining 7 - 8 V for about 2 seconds).
