ABS stands for Anti-lock Braking System, which is a safety feature found in modern cars that helps prevent the wheels from locking up during hard braking, especially on slippery surfaces. Here is some information on its roles in a car, how to diagnose an ABS error, and its DTC codes in point form:
Roles of ABS in a car:
– Prevents the wheels from locking up during hard braking, allowing the driver to maintain steering control.
– Reduces the distance needed to stop the car.
– Improves braking performance on slippery or uneven road surfaces.
– Helps prevent skids and loss of control in emergency situations.
– Provides a safer driving experience for the driver and passengers.
Diagnosing ABS errors:
– ABS warning light on the dashboard stays on or blinks.
– Unusual sounds, such as grinding or buzzing, when the brakes are applied.
– Longer stopping distance than usual.
– Noticeable pedal pulsation or vibration when braking.
– Difficulty maintaining steering control during hard braking.
DTC codes for ABS errors:
– C1011 – ABS Pump Motor Circuit Failure
– C1145 – Right Front Wheel Speed Sensor Input Circuit Failure
– C1155 – Left Front Wheel Speed Sensor Input Circuit Failure
– C1175 – Right Rear Wheel Speed Sensor Input Circuit Failure
– C1233 – Left Front Wheel Speed Circuit Open or Shorted
– C1246 – Pump Motor Relay Circuit Open or Shorted
– C1266 – ABS Motor Relay Circuit Shorted
– C1296 – ABS Hydraulic Pressure Sensor Circuit High Voltage
Note that these are just a few examples of ABS DTC codes, and there may be many more depending on the specific make and model of the car.
