What Does Code C1881 Mean? DTC C1881 indicates a circuit malfunction within the Right Front (RF) height sensor of the vehicle’s air suspension system. The air suspension control module (ASCM), sometimes referred to as the Ride Level Control Module, is responsible for monitoring the operational parameters of each height sensor. These sensors, typically Hall-effect or […]

What Does Code C1882 Mean? DTC C1882 indicates an detected open circuit condition within the Right Front (RF) height sensor electrical circuit of the vehicle’s air suspension system. The Air Suspension Control Module (ASCM) or Suspension Control Module (SCM) is the primary module responsible for monitoring the output of the height sensors and controlling the […]

What Does Code C1883 Mean? DTC C1883 indicates a detected fault within the Right Front (RF) Air Suspension Height Sensor circuit, specifically a “Short To Battery.” This diagnostic trouble code is set by the Air Suspension Control Module (ASCM), also known as the Ride Height Control Module (RHCM), when it detects an abnormally high voltage […]

What Does Code C1884 Mean? DTC C1884 indicates a detected electrical short to ground within the circuit for the Right Front (RF) air suspension height sensor. This is a chassis-related diagnostic trouble code (C-code), signaling an issue specifically within the vehicle’s air suspension system. The Suspension Control Module (SCM), which may be a dedicated Air […]

What Does Code C1885 Mean? DTC C1885 signifies an electrical circuit malfunction detected in the Rear Right (RR) Air Suspension Height Sensor. This code is typically set by the Air Suspension Control Module (ASCM) or Ride Height Control Module (RHCM), rather than the Engine Control Module (ECM) or Powertrain Control Module (PCM), as it pertains […]

What Does Code C1886 Mean? Diagnostic Trouble Code C1886 indicates an “Air Suspension RR Height Sensor Circuit Open” condition. This signifies that the vehicle’s Air Suspension Control Module (ASCM), or the Body Control Module (BCM) if integrated, has detected an interruption or anomaly in the electrical circuit pertaining to the Rear Right (RR) suspension height […]

What Does Code C1887 Mean? DTC C1887 indicates a severe electrical fault within the rear right (RR) air suspension height sensor circuit, specifically a short to battery voltage. This means the dedicated Air Suspension Control Module (ASCM) or Ride Control Module (RCM) has detected a voltage level on the signal wire for the rear right […]

What Does Code C1888 Mean? DTC C1888 signifies an active circuit malfunction within the right rear (RR) air suspension height sensor system, specifically indicating a short circuit to ground. The Air Suspension Control Module (ASCM), also known as an Adaptive Air Suspension Module (AAM) or Suspension Control Module (SCM) depending on the OEM, monitors the […]

What Does Code C1889 Mean? The diagnostic trouble code C1889 signifies a detected fault within the electrical circuit of the Left Front (LF) height sensor in a vehicle’s active air suspension system. This is a chassis (C-code) specific to suspension and steering systems. The Air Suspension Control Module (ASCM), also known in some vehicles as […]

What Does Code C1890 Mean? The diagnostic trouble code C1890 signifies an “Air Suspension LF Height Sensor Circuit Open.” This code is set by the Suspension Control Module (SCM) or a similarly designated body control module responsible for the vehicle’s air suspension system. The SCM continuously monitors the voltage signal provided by the left front […]
