Brake System Control Module "A" System Voltage System Voltage High (C137BA3)
DESCRIPTION If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the +BS terminal voltage deviates due to a malfunction in a power supply or charging syst
Yaw Rate Sensor Circuit Intermittent (C00631F,C006396,C05201F)
DESCRIPTION The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
These DTCs are stored when the skid control ECU (brake actuator assembly) receives a malfunction signal from the yaw rate and acceleration sensor (airbag sensor assembly).
