P1832 - FAULT CODE - OBD2

P1832 INFINITI, NISSAN: TRACTION CONTROL SYSTEM OPERATION SIGNAL

The Traction Control System (TSC) senses how much slip the wheels of the vehicle are likely to experience. If the TSC system notices that one of the wheels is spinning faster than the others, it will automatically apply ABS (Anti-lock Braking System) to that particular wheel, or decrease engine power to that specific wheel.

The operation of the Traction Control System is related to the performance of the Anti-lock Braking System. For this system, manufacturers include wheel speed sensors, which, by means of electrical signals, give information to each controller of the speed, and if necessary, a hydraulic modulator is instructed to pump the brakes. In certain traction control systems, the controller is also responsible for reducing the engine power to these wheels, which are likely to cause slippage. By the time the wheel regains traction, the controller monitors the rotation of the wheel compared to the other wheels.

The P1832 OBDII fault code is set on Infiniti and Nissan vehicles when an error is discovered in the TCS operating signal, which is emitted from the ABS actuator and the electrical unit (control unit) via the CAN bus network.

• Check Engine lamp illuminated.
• ABS malfunction warning light illuminated.

P1832 OBD2 diagnostic code is stored for one of the following reasons:

• Actuator wires or the Anti-Lock Brake System (ABS) control unit could have damage.
• The Controller Area Network (CAN) communication line may be faulty.
• The Anti-Lock Brake System (ABS) actuator or control unit may be in poor condition.

To troubleshoot DTC P1832 OBDII you must do the following:

• Consult the Technical Service Bulletins.
• Using an automotive scanner you should check if additional DTCs to P1832 are stored, especially those that indicate failures of the CAN bus network or ABS. Diagnose these codes according to the order displayed by the scan tool.
• Check the wiring and connections of the actuator circuit and the Anti-Lock Brake System control unit. Look for common deficiencies caused by wear or burnout. If such conditions are found, make appropriate repairs.
• Check the integrity of the ABS actuator as well as its control unit. Note that this is a complex diagnosis, so we recommend that you visit an advanced service center.
