What Does Code C1911 Mean? DTC C1911, “Ride Control RF Shock Actuator Circuit Short To Battery,” indicates a specific electrical fault within the active or semi-active suspension system, targeting the Right Front (RF) shock absorber actuator. The vehicle’s Suspension Control Module (SCM), or a related control unit such as the Body Control Module (BCM) or […]

What Does Code C1912 Mean? DTC C1912 signifies a detected electrical malfunction within the circuit controlling the Right Front (RF) shock absorber actuator, specifically indicating a “Short To Ground”. In modern vehicles equipped with active, adaptive, or electronically controlled suspension systems, a dedicated Ride Control Module (RCM) or Suspension Control Module (SCM) is responsible for […]

What Does Code C1913 Mean? DTC C1913 indicates a detected electrical fault within the circuit of the Left Front (LF) Shock Actuator, which is an integral component of a vehicle’s electronically controlled ride control or adaptive suspension system. The Ride Control Module (RCM), also often referred to as the Suspension Control Module (SCM), is responsible […]

What Does Code C1914 Mean? The diagnostic trouble code (DTC) C1914 indicates an “LF Shock Actuator Circuit Open” condition within the vehicle’s electronically controlled ride control or adaptive suspension system. This ‘C’ code signifies a fault detected by the Suspension Control Module (SCM) or Ride Control Module (RCM), rather than the Powertrain Control Module (PCM), […]

What Does Code C1915 Mean? DTC C1915 indicates a specific electrical fault within the vehicle’s Ride Control System, identifying a Short to Battery condition in the circuit controlling the Left Front (LF) Shock Actuator. Modern vehicles equipped with active or adaptive suspension systems utilize electronically controlled shock absorbers that can vary their damping characteristics. The […]

What Does Code C1916 Mean? DTC C1916 signifies a fault within the ride control system, specifically indicating a short to ground in the electrical circuit for the Left Front (LF) Shock Actuator. Modern vehicles equipped with active or semi-active suspension systems utilize electronically controlled shock absorbers that can dynamically adjust their damping characteristics. The LF […]

What Does Code C1917 Mean? DTC C1917 signifies an Electronic Variable Orifice (EVO) Steering Out-of-Range Fault. This code indicates that the Powertrain Control Module (PCM), or more commonly, a dedicated Steering Control Module (SCM), has detected an electrical or functional discrepancy within the EVO power steering system. The EVO system is a sophisticated, speed-sensitive power […]

What Does Code C1918 Mean? The diagnostic trouble code C1918 signifies an electrical malfunction within the circuit dedicated to the air suspension ride height select switch. This is a Chassis (C-code) specific fault, typically monitored by the vehicle’s Suspension Control Module (SCM), Air Suspension Control Module (ASCM), or sometimes integrated into the Body Control Module […]

What Does Code C1920 Mean? The diagnostic trouble code C1920, typically a manufacturer-specific code (often related to Body, Chassis, or Network systems rather than Powertrain), signifies a “LED #1 Circuit Failure”. This indicates that a specific control module within the vehicle has detected an electrical fault within the circuit responsible for illuminating a particular Light-Emitting […]

What Does Code C1921 Mean? DTC C1921 indicates a detected electrical malfunction within the output circuit controlling the Variable Assist Power Steering (VAPS) solenoid actuator. The Powertrain Control Module (PCM) or a dedicated Steering Control Module (SCM), depending on the vehicle’s architecture, continuously monitors the electrical integrity and operational feedback of the VAPS solenoid circuit.
