What Does Code C1419 Mean? DTC C1419 indicates that the vehicle’s Suspension Control Module (SCM), also sometimes referred to as the Adaptive Damping System (ADS) module or integrated into a Body Control Module (BCM), has detected an open circuit condition in the control circuit for the Right Front (RF) Damper. In modern vehicles equipped with […]

What Does Code C1420 Mean? Diagnostic Trouble Code (DTC) C1420 signifies that the Anti-lock Brake System (ABS) control module, or the Vehicle Stability Control (VSC/ESC) module, has detected an abnormal electrical condition within the hydraulic fluid pressure or flow circuit. Specifically, the code indicates a “short to Vbatt,” meaning the control module is receiving a […]

What Does Code C1421 Mean? Diagnostic Trouble Code C1421 indicates a fault within the Left Front (LF) Damper Control Circuit, specifically a “Short To Battery” condition. This implies that the dedicated Suspension Control Module (SCM), or in some integrated systems, the Powertrain Control Module (PCM) or Body Control Module (BCM), has detected an unintended positive […]

What Does Code C1422 Mean? DTC C1422 indicates a malfunction within the Left Front (LF) Damper circuit, specifically signaling a short to ground condition. In vehicles equipped with active or semi-active suspension systems, each damper (shock absorber or strut) is electronically controlled to vary its damping force. This control is typically achieved via an actuator […]

What Does Code C1423 Mean? DTC C1423 indicates a malfunction within the electrical circuit of the Left Front (LF) suspension damper. This code is specific to vehicles equipped with electronically controlled, adaptive, or active suspension systems, where the damping characteristics of the shock absorber can be dynamically adjusted by a control module. The Suspension Control […]

What Does Code C1424 Mean? DTC C1424 indicates a detected “Damper LF Circuit Open” condition. This code signifies that the vehicle’s Suspension Control Module (SCM), or in some integrated systems, the Powertrain Control Module (PCM) or Body Control Module (BCM), has identified an open circuit in the electrical pathway connected to the Left Front (LF) […]

What Does Code C1425 Mean? DTC C1425 indicates a detected electrical short circuit to ground within the control circuit of the Rear Right (RR) damper unit. This code is typically set in vehicles equipped with electronically controlled damping systems, such as adaptive or active suspensions, where the damping characteristics of each shock absorber or strut […]

What Does Code C1426 Mean? Diagnostic Trouble Code C1426 indicates a malfunction within the Rear Right (RR) Damper Control Circuit, specifically identifying a condition where the circuit is experiencing a short to battery voltage. This code is typically set by the Suspension Control Module (SCM) or, in some integrated systems, the Powertrain Control Module (PCM), […]

What Does Code C1427 Mean? DTC C1427 signifies an open circuit condition detected within the control circuit of the rear right (RR) electronically controlled damper, often referred to as an adaptive shock absorber or strut. In modern vehicles equipped with active or adaptive suspension systems, the Suspension Control Module (SCM), or sometimes the Powertrain Control […]

What Does Code C1428 Mean? The diagnostic trouble code C1428 indicates a detected electrical anomaly within the circuit controlling the Rear Right (RR) damper. In vehicles equipped with electronically controlled suspension systems, the Powertrain Control Module (PCM), Suspension Control Module (SCM), or Body Control Module (BCM) continuously monitors the electrical integrity and operational feedback of […]
