What Does Code C1943 Mean? DTC C1943 signifies an “Airbag Deployment Indication Input Fault” within the Supplemental Restraint System (SRS). This code is generated by the Restraint Control Module (RCM), also commonly known as the Airbag Control Module (ACM), when it detects an anomaly in the input signal or internal logic concerning an airbag deployment […]

What Does Code C1944 Mean? The diagnostic trouble code C1944, often defined as “Gauge Driver Circuit Fault,” indicates that a control module, typically the Body Control Module (BCM) or the Instrument Panel Cluster (IPC) module itself, has detected an electrical anomaly within the circuit responsible for driving one or more gauges in the instrument cluster. […]

What Does Code C1945 Mean? Diagnostic Trouble Code (DTC) C1945 indicates that the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has detected a logical inconsistency between the reported status of the transmission’s Park switch and the vehicle’s detected speed. Specifically, the control module is receiving a signal from the Park/Neutral Position (PNP) switch, […]

What Does Code C1946 Mean? The C1946 diagnostic trouble code signifies an “Open Circuit” condition detected within the electrical circuit of the seat track position switch. This critical switch provides vital data to the vehicle’s safety systems, primarily the Supplemental Restraint System (SRS), often managed by the Restraint Control Module (RCM), or in some applications, […]

What Does Code C1947 Mean? DTC C1947 signifies a “Seat Track Position Switch Circuit Short to Ground.” This code is typically set by a chassis control module, such as the Occupant Classification System (OCS) module, Airbag Control Module (ACM/SRS module), or the Body Control Module (BCM), which then may communicate the fault to the Powertrain […]

What Does Code C1948 Mean? DTC C1948 indicates that the vehicle’s Restraint Control Module (RCM), also commonly referred to as the Airbag Control Module (ACM) or Occupant Classification System (OCS) module, has detected an issue with the electrical resistance within the circuit for the Seat Track Position Switch (STPS). This switch, or often an array […]

What Does Code C1949 Mean? DTC C1949 signifies an detected open circuit condition within the accelerometer sensor circuit. This code is typically logged by the vehicle’s Restraint Control Module (RCM), Airbag Control Module (ACM), or a dedicated Chassis Control Module, rather than the Engine Control Module (ECM/PCM) directly, although the ECM/PCM may log it as […]

What Does Code C1950 Mean? DTC C1950 indicates a detected fault within the Accelerometer Sensor Circuit. This code is typically a chassis-related trouble code (C-code), often stored by the Anti-lock Braking System (ABS) module, Electronic Stability Program (ESP) module, Vehicle Stability Control (VSC) module, or a similar integrated chassis control unit, rather than the Powertrain […]

What Does Code C1951 Mean? DTC C1951 indicates a detected open circuit within the electrical system of the Lateral Accelerometer Sensor. This sensor, a critical component of the vehicle’s chassis control systems, measures the lateral (sideways) acceleration forces acting upon the vehicle. This data is essential for the proper functioning of systems such as the […]

What Does Code C1952 Mean? Diagnostic Trouble Code C1952 indicates that the vehicle’s Anti-lock Braking System (ABS) module, Electronic Stability Control (ESC) module, or Vehicle Stability Control (VSC) module has detected an open circuit condition within the yaw rate sensor’s electrical circuit. The yaw rate sensor is a critical component of a vehicle’s active safety […]
