WHEN MECHANICAL KEY IS USED
With the key inserted into the key switch, and the ignition switch in the LOCK or ACC position, when driver's
door is opened, the warning chime will sound.
 BCM detects key inserted into the ignition switch, and sends key warning signal to combination meter with
CAN communication line.
 When combination meter receives key warning signal, it sounds the warning chime.
WHEN INTELLIGENT KEY IS CARRIED WITH THE DRIVER
Refer to DLK-16, "Work Flow" (without super lock) or DLK-240, "Work Flow" (with super lock).

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.MWI-24
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). MWI-25
