C1096 – OBD-II DTC

OBD-II DTC C1096 – ABS Hydraulic Pump Motor Circuit Open

DTC C1096 meaning

DTC C1096 refers to an issue with the ABS (Anti-lock Braking System) hydraulic pump motor circuit, specifically indicating an open circuit condition. This means that there is a break in the electrical path that powers the hydraulic pump motor, preventing it from functioning properly. The ABS system relies on this motor to maintain brake performance and stability during various driving conditions.

DTC C1096 symptoms

Common symptoms associated with DTC C1096 may include:

  • Illumination of the ABS warning light on the dashboard.
  • Loss of ABS functionality, leading to potential wheel lock-up during hard braking.
  • Increased stopping distances due to the failure of the ABS system.
  • Possible activation of the traction control or stability control warning lights.

DTC C1096 causes

Several factors can lead to the occurrence of DTC C1096, including:

  • Damaged or frayed wiring in the ABS hydraulic pump motor circuit.
  • Corroded or loose electrical connectors affecting the circuit integrity.
  • Faulty ABS hydraulic pump motor that fails to operate.
  • Issues with the ABS control module that may prevent proper communication.

DTC C1096 seriousness

DTC C1096 is considered a serious issue as it directly impacts the vehicle’s braking system. The inability of the ABS to function can lead to reduced braking efficiency, especially in slippery conditions, increasing the risk of accidents. It is crucial to address this code promptly to ensure safe vehicle operation.

How to diagnose DTC C1096

To diagnose DTC C1096, follow these steps:

  1. Use an OBD-II scanner to confirm the presence of the C1096 code.
