Diagnostic Trouble Code Chart 1
NOTICE:
When removing the part, turn the ignition switch to OFF.
HINT:
• Using SST 09843-18040, it connect the terminal Tc and CG of DLC3.
• If any abnormality is not found when inspecting parts, inspect the ECU and ground points for poor contact.
• If a malfunction code is displayed during the DTC check, check the circuit listed that code. For details of each code, turn to the page referred to under the "See page" for respective "DTC No." in the DTC chart.
• When 2 or more DTC's are recorded, and the problem is not identified, perform circuit inspection of the other DTC's.

The speed sensor detects wheel speed and transmits the appropriate signals to the ECU. These signals are used for control of the ABS control system. Each of the front and rear rotors has 48 serrations.
When the rotors rotate, the magnetic field generated by the permanent magnet in the speed sensor induces an AC voltage. Since the frequency of this AC voltage changes in direct proportion to the speed of the rotor, the frequency is used by the ECU to detect the speed of each wheel.
