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 seconds) or 10A fuse [No. 19, located in the fuse block (J/B)] is dis-
connected. DI-34
METER COMM CIRC [B2202]
Malfunction is detected in communication of between combination meter and unified
meter and A/C amp. DI-34
VEHICLE SPEED CIRC [B2205] When an erroneous speed signal is input for 1 second.
CAUTION:
Even when there is no malfunction on speed signal system, malfunction may be
misinterpreted when battery has low voltage (when maintaining 7 - 8 V for about
2 seconds). DI-37

WARNING LAMPSPFP:24814
System DescriptionNKS003HX
OIL PRESSURE WARNING LAMP
Oil pressure warning lamp turns ON when reducing engine oil pressure abnormally.

IPDM E/R reads oil pressure switch signal from oil pressure switch, and transmits the signal to unified
meter and A/C amp. through BCM with CAN communication.

Unified meter and A/C amp. transmits oil pressure switch signal to combination meter with communication
line.

Combination meter turns oil pressure warning lamp ON with received oil pressure switch signal.
