What Does Code C1155 Mean? Diagnostic Trouble Code (DTC) C1155 signifies an input circuit fault detected within the Left Front (LF) Wheel Speed Sensor system. This code is typically set by the Anti-lock Braking System (ABS) control module, which is often integrated into or communicates directly with the Brake Control Module (BCM) or Vehicle Stability […]

What Does Code C1156 Mean? DTC C1156 indicates a detected open circuit within the Left Front (LF) Wheel Speed Sensor electrical circuit. This diagnostic trouble code is typically set by the Anti-lock Brake System (ABS) Control Module (also known as the Electronic Brake Control Module or EBCM), rather than directly by the Engine Control Module […]

What Does Code C1157 Mean? DTC C1157 indicates a detected failure within the “Park Brake Actuator Assembly Switch Applied Circuit.” This code is typically set by the Electronic Parking Brake (EPB) control module, Body Control Module (BCM), or a similar vehicle network control unit responsible for supervising the EPB system. It signifies that the control […]

What Does Code C1158 Mean? The diagnostic trouble code C1158 signifies a “Speed Wheel Sensor LF Coherency Fault” detected within the vehicle’s Anti-lock Braking System (ABS), Traction Control System (TCS), and Vehicle Stability Control (VSC) module. While an Engine Control Module (ECM) or Powertrain Control Module (PCM) may log this chassis-related code, the primary diagnostic […]

What Does Code C1159 Mean? The diagnostic trouble code C1159 indicates a detected electrical fault within the Hydraulic Fluid Pressure/Flow Circuit, specifically identifying a short to ground. This code is typically set by the Anti-lock Braking System (ABS) control module, which often integrates functions for Traction Control System (TCS) and Electronic Stability Control (ESC/ESP). The […]

What Does Code C1161 Mean? DTC C1161 signifies an electrical fault within the “Air Pressure Low” circuit, specifically indicating a short to ground condition. As a “C” code, it falls under the Chassis system category, commonly pointing towards issues within the vehicle’s air suspension system or a similar chassis-related pneumatic system that monitors low air […]

What Does Code C1162 Mean? DTC C1162 signifies a detected failure within the “Park Brake Switch #2 Released Circuit.” This code is typically set by the vehicle’s Chassis Control Module (CCM), Parking Brake Control Module (PBCM), or a combined ABS/Electronic Stability Control (ESC) module, which is responsible for monitoring the state of the parking brake […]

What Does Code C1163 Mean? DTC C1163 indicates a detected electrical fault in the circuit associated with the Park Brake Switch #2, specifically reporting a short to ground condition. In modern automotive systems, the parking brake status is a critical input for various control modules, including the Anti-lock Braking System (ABS), Electronic Stability Program (ESP), […]

What Does Code C1164 Mean? DTC C1164 signifies a circuit malfunction within the Park Brake Actuator Assembly Switch. This code is typically set by the vehicle’s Electronic Brake Control Module (EBCM) or a dedicated Parking Brake Control Module (PBCM), which then communicates this fault to the Powertrain Control Module (PCM) or Engine Control Module (ECM) […]

What Does Code C1165 Mean? Diagnostic Trouble Code (DTC) C1165 signifies an electrical malfunction detected within the input circuit of the Right Rear (RR) wheel speed sensor. This code is typically set by the Anti-lock Brake System (ABS) module, also referred to as the Vehicle Stability Control (VSC) module or Traction Control System (TCS) module, […]
