P1750B FRONT LEFT SPEED SENSOR (With ABS)
Описание ошибки P1750B
Wheel speed sensor is active hall-sensor type and good at temperature and noise chariteristic. Digital wave is produced as tone wheel rotate according as hall sensor principle. Frequency of duty wave is changed in proportion to rotation of tone wheel and HECU calculate vehicle speed by this frequency. In case ABS (or ESP) system is applied to the vehicle, wheel speed sensor signal is sent to 4WD-ECM (TCCU) by CAN communication. This failure code is related to the TCCU communication line of the ESP(ABS CONTROL MODULE) and is set if there is no input signal to TCCU.

● ABS MODULE,TCCU connector looseness and poor terminal to wire connection.
● Wheel sensor comm line circuit open/short.
● Faulty Wheel sensor .
● Faulty ABS MODULE .
● Faulty TCCU .
