What Does Code C1440 Mean? DTC C1440 signifies a detected malfunction within the primary pressure transducer circuit. As a “C” (Chassis) diagnostic trouble code, it typically points to an issue with a pressure sensor integral to the vehicle’s Anti-lock Braking System (ABS), Vehicle Stability Control (VSC), or Traction Control (TRAC) systems. Specifically, it indicates that […]

What Does Code C1441 Mean? DTC C1441, an OBD-II Body Chassis (C-code) diagnostic trouble code, signifies that the vehicle’s Power Steering Control Module (PSCM) has detected an anomaly in the “Phase A” signal circuit from the steering angle sensor (SAS) or an integrated steering resolver. In modern Electric Power Steering (EPS) systems, the SAS is […]

What Does Code C1442 Mean? DTC C1442 signifies that the vehicle’s control module, typically the Electronic Power Steering (EPS) Control Module or an integrated stability control module (such as the ABS/ESC module), has detected an anomaly or absence of signal from the “Phase B” circuit of the Steering Angle Sensor (SAS). The Steering Angle Sensor […]

What Does Code C1443 Mean? DTC C1443 signifies a detected malfunction within the “Steering Phase A Circuit,” specifically indicating a short to ground condition. This code typically pertains to the Electric Power Steering (EPS) system or the Steering Angle Sensor (SAS) circuit, both of which are critical for the proper operation of modern vehicle dynamics […]

What Does Code C1444 Mean? The diagnostic trouble code C1444 signifies a detected electrical fault within the “Steering Phase B Circuit,” specifically indicating a short to ground condition. This code typically pertains to the Electric Power Steering (EPS) system or a related Steering Angle Sensor (SAS) subsystem. In the context of an EPS system, “Phase […]

What Does Code C1445 Mean? DTC C1445 signifies a malfunction within the Vehicle Speed Sensor (VSS) signal circuit, specifically as interpreted by the Skid Control ECU, often encompassing the Anti-lock Braking System (ABS), Vehicle Stability Control (VSC), and Traction Control (TRAC) modules. Unlike powertrain (P-codes) related VSS failures which typically point to the primary vehicle […]

What Does Code C1446 Mean? The diagnostic trouble code C1446 indicates a malfunction within the brake switch circuit. This code is typically generated by the Vehicle Stability Control (VSC) module, Anti-lock Braking System (ABS) module, or the Powertrain Control Module (PCM), depending on the vehicle manufacturer and system architecture. The control module monitors the input […]

What Does Code C1447 Mean? DTC C1447 signifies a detected electrical malfunction within the specific circuit responsible for the “request” signal transmission from the Traction Control Module (TCM) to the Powertrain Control Module (PCM) or Engine Control Module (ECM). In modern vehicle architectures, the TCM is frequently integrated within the Anti-lock Braking System (ABS) control […]

What Does Code C1448 Mean? DTC C1448 signifies a detected electrical malfunction within the warning circuit dedicated to the vehicle’s Adaptive Damping System (ADS) or Adaptive Ride Control (ARC). This code is typically set by the Suspension Control Module (SCM), Body Control Module (BCM), or an integrated control module responsible for overseeing the adaptive suspension, […]

What Does Code C1449 Mean? DTC C1449 signifies a Traction Control Motor Coherency Fault within the vehicle’s Anti-lock Braking System (ABS) and Traction Control System (TCS) module. This code is specifically triggered when the ABS/TCS control module detects an inconsistency or failure in the commanded operation and/or feedback from the electric motor responsible for actuating […]
