CAN COMM CIRC [U1000]Malfunction is detected in CAN communication lines.
CAUTION:
Even when there is no malfunction on CAN communication system, malfunc-
tion may be misinterpreted when battery has low voltage (when maintaining 7 -
8 V for about 2 seconds) or 10A fuse [No. 19, located in the fuse block (J/B)] is
removed.DI-26
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, malfunctions may
be misinterpreted when battery has low voltage (when maintaining 7 - 8 V for
about 2 seconds).DI-26

WARNING CHIMEPFP:24814
System DescriptionEKS00L9D
lBuzzer for warning chime system is installed in the combination meter.
lThe buzzer sounds at the following conditions:
–When combination meter receives buzzer output signal with CAN communication line
–When combination meter judges warning chime sound condition is found
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
lthrough 50A fusible link (letterG, located in the fuse and fusible link box)
lto BCM terminal 57.
With ignition switch in the ON or START position, power is supplied
lthrough 10A fuse [No. 1, located in the fuse block (J/B)]
lto BCM terminal 3.
Ground is supplied
lto BCM terminal 55
lthrough grounds M21, M80 and M83.
LIGHT WARNING CHIME
With ignition switch in OFF or ACC position, driver's door open, and lighting switch in 1ST or 2ND position, the
light warning chime will sound.
lBCM detects ignition switch in OFF or ACC position, front door switch (driver side) ON, and lighting switch
in 1ST or 2ND position. And then transmits buzzer output signal (light warning chime) to combination
meter with CAN communication line.
lWhen combination meter receives buzzer output signal (light warning chime), it sounds the buzzer.
NOTE:
For further details of combination switch, refer toBCS-3, "
COMBINATION SWITCH READING FUNCTION".
KEY REMINDER WARNING CHIME
Key reminder chime sounds, at the same time, when key reminder system starts operating.
key reminder chime also sounds when the following three conditions are simultaneously met.
lKey is inserted in the ignition key cylinder
lDriver¢s door is opened
lThe setting of driver¢s door lock knob is “LOCK”
For information regarding key reminder system, refer toBL-21, "
POWER DOOR LOCK SYSTEM".
LOW-FUEL WARNING CHIME
Low-fuel warning chime sounds, when low-fuel warning lamp is turned ON.
Combination meter sounds warning chime three times when low-fuel warning lamp turns ON.
