DTC C1271: Low Output Signal of Front Speed Sensor RH (Test Mode DTC); DTC C1272: Low Output Signal of Front Speed Sensor LH (Test Mode DTC); DTC C1464: Front Speed Sensor RH Circuit; DTC C1465: Front Speed Sensor LH Circuit [11/2018 - 02/2019]: Description
Each speed sensor detects the wheel speed and sends the signals to the skid control ECU (brake booster with master cylinder assembly). These signals are used for ABS control.
DTCs C1271 and C1272 are cleared when the speed sensor sends a wheel speed signal or when Test Mode ends. DTCs C1271 and C1272 are output only in Test Mode.
