DESCRIPTION When a new
driving support ECU assembly is installed, it receives vehicle
specification information (destination, steering wheel position, etc.)
from the main body ECU (multiplex network body ECU) and stores the
information. DTC C1A02 is stored when the
driving support ECU assembly receives the vehicle specification
information from the main body ECU (multiplex network body ECU) but
cannot store it. |
DTC No. | Detection Item |
DTC Detection Condition | Trouble Area | |
C1A02 | Vehicle Information Not Obtained |
The
vehicle specification information of the main body ECU (multiplex
network body ECU) and driving support ECU assembly do not match for 1
second or more while the vehicle is being driven at a speed of 50 km/h
(32 mph) or more. | Driving support ECU assembly | CAUTION / NOTICE / HINT
NOTICE:
- When replacing the driving support ECU assembly, always replace it with a
new one. If a driving support ECU assembly which was installed to
another vehicle is used, the information stored in the driving support
ECU assembly will not match the information from the vehicle. As a
result, a DTC may be stored.
- The pre-collision system uses the CAN communication system. First,
confirm that there are no malfunctions in the CAN communication system.
