Toyota Code C1405 is open or short in the front speed sensor RH circuit, which various issues can cause. These issues range from the front speed sensor RH/LH, the speed sensor circuit, or the brake actuator assembly (Skid control ECU). This can be a difficult code to diagnose and fix, as multiple issues can cause it. To properly analyze and resolve the issue, it is important to understand the causes and possible solutions for the Toyota Code C1405.

Causes and Solutions for Toyota Code C1405
| Cause | Solution |
|---|---|
| Front Speed Sensor RH/LH | Check the speed sensor for corrosion or any damage. |
| Speed Sensor Circuit | Check the wiring and connections for any loose connections or broken wires. |
| Brake Actuator Assembly (Skid Control ECU) | Replace the ECU if needed. |
| Corroded Wires | Clean the wires and connections. |
Front Speed Sensor RH/LH
When diagnosing the Toyota Code C1405, the first thing to check is the front speed sensors. If the sensors are corrupted or damaged, this can cause the circuit to open or short and trigger the code. The sensors should be checked for damage or corrosion and replaced if necessary.
Speed Sensor Circuit
The next thing to check is the speed sensor circuit. This includes the wiring and connections that go to the sensors. If there are any loose connections or broken wires, this can cause an opening or short in the circuit and trigger the code. The wiring and connections should be checked for any signs of damage or corrosion and repaired or replaced if necessary.

Brake Actuator Assembly (Skid Control ECU)
The brake actuator assembly (Skid Control ECU) is also a possible cause of the code. If the ECU is faulty, it can trigger the code by causing an opening or short in the circuit. The ECU should be tested and replaced if necessary.
Corroded Wires
Finally, corroded wires can also cause the code. If the wires or connections are corroded, this can generate an open or short circuit and trigger the code. The cables and connections should be cleaned and repaired if necessary.
