What Does Code C1505 Mean? DTC C1505 indicates a malfunction within the Dynamic Stability Control (DSC) or Electronic Stability Program (ESP) system, specifically pertaining to the left rear hydraulic control valve. This code signifies that the vehicle’s ABS/DSC control module has detected an electrical or functional fault with the solenoid valve responsible for modulating brake […]

What Does Code C1506 Mean? DTC C1506 indicates a malfunction within the Dynamic Stability Control (DSC) system specifically related to the right rear brake pressure control valve. The DSC system, often integrated with the Anti-lock Braking System (ABS), utilizes a hydraulic control unit (HCU) equipped with a series of solenoid valves. These valves modulate hydraulic […]

What Does Code C1507 Mean? DTC C1507, or “Traction Control of Brake Exceeds Time-Out,” signifies a critical fault within the Anti-lock Braking System (ABS) and Traction Control System (TCS) module’s ability to execute a commanded brake application for traction control purposes. This code is typically set when the ABS/TCS control module initiates a brake intervention […]

What Does Code C1508 Mean? The diagnostic trouble code C1508, “Traction Control of Engine Exceeds Time-Out,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an unexpected or delayed response from the engine’s torque management system during an active traction control event. In modern vehicles, the Traction Control System (TCS), […]

What Does Code C1510 Mean? DTC C1510 indicates a “Right Front Wheel Pressure Reduction Performance Problem” within the vehicle’s Anti-lock Braking System (ABS) or Electronic Brake Control Module (EBCM). This code signifies that the EBCM has detected an inability to effectively reduce hydraulic pressure to the right front brake caliper when commanded to do so. […]

What Does Code C1511 Mean? The diagnostic trouble code C1511 signifies a detected anomaly within the Anti-lock Braking System (ABS) or Electronic Stability Control (ESC) module related to the hydraulic pressure reduction performance at the left front wheel. Specifically, it indicates that during an ABS or ESC activation event, or during system self-tests, the brake […]

What Does Code C1512 Mean? Diagnostic Trouble Code (DTC) C1512 indicates a “Right Rear Wheel Pressure Reduction Performance Problem.” This is a manufacturer-specific C-body (chassis) code primarily associated with the Anti-lock Braking System (ABS), Electronic Stability Control (ESC), or Traction Control System (TCS) of the vehicle. The Engine Control Module (ECM) or more precisely, the […]

What Does Code C1513 Mean? The diagnostic trouble code C1513 indicates a detected “Left Rear Wheel Pressure Reduction Performance Problem” within the Anti-lock Braking System (ABS), Traction Control System (TCS), or Vehicle Stability Control (VSC) module. This code signifies that the powertrain control module (PCM), or more specifically the ABS/VSC control module, has identified an […]

What Does Code C1699 Mean? Diagnostic Trouble Code (DTC) C1699 indicates a detected electrical fault within the circuit of the Left Rear Wheel Speed Sensor. Specifically, the Anti-lock Brake System (ABS) Control Module (also known as the Electronic Brake Control Module – EBCM, or Vehicle Stability Control Module – VSCM) has identified a condition where […]

What Does Code C1700 Mean? The diagnostic trouble code C1700, typically associated with the chassis control systems, signifies an electrical malfunction within the circuit of the Left Rear Wheel Speed Sensor. The Anti-lock Braking System (ABS) control module, which may be an independent unit or integrated within the Powertrain Control Module (PCM) or Electronic Brake […]
