What Does Code C1177 Mean? DTC C1177 signifies a “Park Brake Actuator Assembly Switch Released Circuit Failure.” This code is typically set by the Electric Park Brake (EPB) control module, which may be integrated into the Anti-lock Braking System (ABS) module or a dedicated Chassis Control Module (CCM). The EPB system utilizes an electromechanical actuator, […]

What Does Code C1178 Mean? The diagnostic trouble code C1178 signifies a Left Rear Wheel Speed Sensor Coherency Fault. This code is typically set by the Anti-lock Braking System (ABS) control module, which is often integrated into the Electronic Brake Control Module (EBCM) or Vehicle Stability Control (VSC) system. A coherency fault indicates an inconsistency […]

What Does Code C1179 Mean? Diagnostic Trouble Code C1179, often categorized as a chassis code, indicates a malfunction within the vehicle’s speed control system, specifically identifying a Speed Control Actuator Assembly Cable Slack Failure. This code is typically set by the Powertrain Control Module (PCM), Cruise Control Module (CCM), or an integrated Body Control Module […]

What Does Code C1180 Mean? DTC C1180 signifies a malfunction detected within the Park Brake Valve Solenoid #1 Sense Input Circuit. This code is typically set by the Electronic Parking Brake (EPB) Control Module, the Brake Control Module (BCM), or in some architectures, a dedicated Chassis Control Module. The solenoid in question is an integral […]

What Does Code C1181 Mean? The diagnostic trouble code C1181 signifies a detected electrical fault within the “Park Brake Valve Solenoid #1 Sense Input Circuit,” specifically indicating a short to ground condition. As a chassis (C-code) fault, C1181 directly relates to the vehicle’s electronic braking or parking brake system. This code is typically set by […]

What Does Code C1182 Mean? DTC C1182 indicates a detected malfunction within the park lamp flash relay circuit. This code is typically set by the Body Control Module (BCM), Security Control Module (SCM), or a similar integrated control unit responsible for vehicle lighting and accessory functions, rather than the Engine Control Module (ECM/PCM). The control […]

What Does Code C1183 Mean? DTC C1183 indicates a detected electrical anomaly within the park lamp flash relay circuit, specifically a “Short to Battery.” This diagnostic trouble code is typically set by the Body Control Module (BCM), Lighting Control Module (LCM), or a dedicated Security Control Module, rather than the Engine Control Module (ECM/PCM), as […]

What Does Code C1184 Mean? Diagnostic Trouble Code (DTC) C1184 indicates that the Anti-lock Braking System (ABS) control module has detected an internal malfunction or a critical operational fault that renders the entire ABS system inoperable. This code signifies a severe system integrity failure, not merely a fault with an individual component like a wheel […]

What Does Code C1185 Mean? DTC C1185 signifies an ABS Power Relay Output Circuit Failure. This code is set by the Electronic Brake Control Module (EBCM), also sometimes referred to as the Anti-lock Brake System (ABS) module or Vehicle Stability Control (VSC) module, when it detects an electrical anomaly within the circuit that controls the […]

What Does Code C1186 Mean? DTC C1186 signifies an “ABS Power Relay Output Open Circuit.” This code indicates that the Electronic Brake Control Module (EBCM), also commonly referred to as the ABS module, has detected an open circuit condition in the electrical pathway supplied by the Anti-lock Brake System (ABS) power relay. The ABS power […]
