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.

Pressure Sensor Circuit (B1423/23)
DESCRIPTION
This DTC is stored if refrigerant pressure on the high pressure side is extremely
low (176 kPa (1.8 kgf/cm2, 26 psi) or less) or extremely high (3140 kPa (32.0 kgf/cm2,
455 psi) or more). The air conditioner pressure sensor, which is installed on the
pipe on the high pressure side ...
