Hello , thanks for your question in the autoaid Community.
Your described fault Codes means:
5104 SPEED SENSOR FRONT LEFT WHEEL SPEED NOT PLAUSIBLE
5703 CAN-BUS COMMUNICATION WITH DASHBOARD DISTURBED
5115 SPEED SENSOR FRONT RIGHT OF INTERNAL ERROR
5112 SPEED SENSOR FRONT RIGHT SIGNAL ERROR
5707 INTERNAL CONTROLLER ERROR
5114 SPEED SENSOR FRONT RIGHT WHEEL SPEED NOT PLAUSIBLE
The codes 5104, 5112, 5114 and 5115 are fault codes for the speed sensors.
5104 should be the speed sensor or his wires and connection of this part. Look for the correct connection and if you have the correct wiring diagram, them measure the signal from this sensor if you have an oscilloscope, or an analogue multimeter.
You also can measure the wirings to the connection from the speed sensor, if there is already okay, then renew this sensor.
5112-5115 shows direct to the sensor front right. You should check this part at the same procedure likes the 5104 error.
But i think that both sensors are faulty.
5707 is not so good, because it could be an error in the ABS-ECU and this have only then to renew.
But check the errors from the upper text and then erase all the codes and look if there, after your repair, already okay.
