What Does Code C1100 Mean? DTC C1100 indicates an electrical fault within the Anti-lock Braking System (ABS) pump motor circuit. The ABS Control Module (often referred to as the ABS Module, Electronic Brake Control Module – EBCM, or Hydraulic Control Unit – HCU) is responsible for monitoring the operational status of the ABS pump motor. […]

What Does Code C1101 Mean? DTC C1101 signifies an “ABS Hydraulic Valve Circuit Failure.” This code indicates that the Anti-lock Braking System (ABS) Control Module, often integrated with the Electronic Brake Control Module (EBCM), has detected an electrical fault within the circuit that controls one or more of the hydraulic solenoid valves located within the […]

What Does Code C1102 Mean? Diagnostic Trouble Code C1102 signifies an “ABS Acceleration Switch Circuit Failure.” This code is typically set when the Anti-lock Braking System (ABS) control module, or more broadly, the Vehicle Stability Control (VSC) or Traction Control System (TCS) module, detects an electrical malfunction within the circuit for the vehicle’s acceleration sensor. […]

What Does Code C1103 Mean? The diagnostic trouble code C1103 indicates an electrical malfunction within the Anti-lock Braking System (ABS) hydraulic brake pressure switch circuit. This switch, often referred to as a brake fluid pressure sensor or hydraulic pressure sensor, monitors the hydraulic pressure within the brake lines, typically at the master cylinder or ABS […]

What Does Code C1104 Mean? DTC C1104 signifies a detected electrical fault within the circuit dedicated to illuminating the Traction Control Active warning lamp on the vehicle’s instrument cluster. Specifically, the code indicates a “Circuit Short to Battery.” This diagnostic trouble code is typically registered by the Anti-lock Braking System (ABS) control module, which often […]

What Does Code C1105 Mean? Diagnostic Trouble Code (DTC) C1105 indicates a fault within the circuit controlling the Traction Control Disable Lamp, specifically a “Circuit Short to Battery.” This code is typically set by the Anti-lock Brake System (ABS) module or the Traction Control Module (TCM), as C-codes relate to chassis systems. The module monitors […]

What Does Code C1106 Mean? Diagnostic Trouble Code C1106 indicates a detected fault within the Traction Control Disable Switch Circuit, specifically a Short to Battery condition. This chassis code is typically identified by the Anti-lock Braking System (ABS) or Traction Control System (TCS) control module, which often resides as an integral part of the Powertrain […]

What Does Code C1107 Mean? Diagnostic Trouble Code C1107 indicates an “ABS Function Enabled Input Circuit Failure.” This is a chassis (C-prefix) code specifically pertaining to the Anti-lock Braking System (ABS) and its integrated functions, such as Traction Control (TC) or Electronic Stability Program (ESP). The ABS control module, often referred to as the Electronic […]

What Does Code C1109 Mean? DTC C1109 indicates a detected malfunction within the vehicle’s speed control (cruise control) system, specifically referencing a “Speed Control Actuator Assembly Cable Release Failure.” The Powertrain Control Module (PCM), or Engine Control Module (ECM) in some applications, sets this code when it commands the speed control actuator to release the […]

What Does Code C1110 Mean? The diagnostic trouble code C1110 signifies an electrical fault within the Anti-lock Braking System’s (ABS) power relay coil circuit. This code is typically set by the Electronic Brake Control Module (EBCM) or Hydraulic Control Unit (HCU), which is the dedicated control unit for the ABS system, although some manufacturers may […]
