Current trouble
• Connector(s) or wiring harness in the CAN bus
lines between the combination meter and the
multi-center display unit (middle grade type), the
power supply system to the display unit, the dis-
play unit itself, or the combination meter may be
defective.
Past trouble
• Carry out diagnosis with particular emphasis on
connector(s) or wiring harness in the CAN bus
lines between the combination meter and the
multi-center display unit (middle grade type), the
power supply system to the display unit. For diag-
nosis procedures, refer to "How to cope with past
trouble" (Refer to GROUP 00, How to Use Trou-
bleshooting/Inspection Service Points
