Malfunction
Reference
page
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. 3, located in the fuse block (J/B)] is disconnected.
VEHICLE SPEED
CIRC
[B2205]
Malfunction is detected when an erroneous speed signal is input.
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).
