Diameter of the Tire is not Uniform (C1337)
DESCRIPTION
The skid control ECU (brake actuator assembly) measures the speed of each wheel
by receiving signals from the speed sensors. These signals are used for recognizing
whether all 4 wheels are operating properly. Therefore, all wheel signals must indicate
the same speed.

Engine Coolant Temperature Receiver Gauge Malfunction
DESCRIPTION
In this circuit, the meter CPU receives engine coolant temperature signals from
the ECM using the CAN communication system (CAN V1 Bus). The meter CPU displays
engine coolant temperature that is calculated based on the data received from the
ECM.
