What Does Code C1963 Mean? DTC C1963, defined as “Stability Control Inhibit Warning,” indicates that the vehicle’s Electronic Stability Control (ESC) system has detected a condition that prevents it from fully operating or has actively inhibited its functionality. This code is typically set by the Anti-lock Brake System (ABS) module or a dedicated Stability Control […]

What Does Code B1200 Mean? DTC B1200 signifies a “Climate Control Pushbutton Circuit Failure,” indicating a detected electrical malfunction within the circuit associated with one or more pushbuttons on the vehicle’s Heating, Ventilation, and Air Conditioning (HVAC) control panel. This code is typically manufacturer-specific, commonly appearing in Ford and Mazda vehicles, and is stored in […]

What Does Code B1201 Mean? DTC B1201 signifies a Fuel Sender Circuit Failure within the vehicle’s electrical system, specifically related to the fuel level monitoring subsystem. This code is generated by the Powertrain Control Module (PCM) or Engine Control Module (ECM), or sometimes a dedicated Body Control Module (BCM) or Instrument Cluster, which monitors the […]

What Does Code B1202 Mean? DTC B1202 signifies an open circuit condition detected within the fuel level sender unit’s electrical circuit. This code is typically set by the Body Control Module (BCM) or the Instrument Cluster Module (ICM), which are responsible for monitoring the fuel tank’s actual fuel level via a resistive sensor. The fuel […]

What Does Code B1203 Mean? DTC B1203, officially defined as “Fuel Sender Circuit Short To Battery,” indicates a specific electrical anomaly within the vehicle’s fuel level monitoring system. The Powertrain Control Module (PCM), or in some vehicle architectures, the Body Control Module (BCM) or Instrument Cluster (IC), is responsible for monitoring the fuel tank’s level. […]

What Does Code B1204 Mean? The diagnostic trouble code B1204, “Fuel Sender Circuit Short To Ground,” indicates that the vehicle’s Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected an electrical short circuit to ground within the fuel level sender unit’s electrical circuit. The fuel sender unit, typically integrated into the fuel pump […]

What Does Code B1205 Mean? DTC B1205, often described as “EIC Switch-1 Assembly Circuit Failure,” indicates that the Body Control Module (BCM) or Instrument Cluster (IC), which typically acts as the primary monitoring module for interior electronics, has detected an electrical malfunction within the circuit of the Electronic Instrument Cluster (EIC) Switch-1 Assembly. The EIC […]

What Does Code B1206 Mean? Diagnostic Trouble Code (DTC) B1206 signifies an “EIC Switch-1 Assembly Circuit Open.” In automotive diagnostics, “EIC” most commonly refers to the Electronic Instrument Cluster or Engine Information Center, indicating that the fault lies within a switch assembly that provides input to this module. “Switch-1 Assembly” implies a specific, often critical, […]

What Does Code B1207 Mean? DTC B1207 indicates a specific electrical fault within the vehicle’s Body Electrical system, specifically referencing the “EIC Switch-1 Assembly Circuit Short To Battery.” EIC typically refers to the Electronic Instrument Cluster or Engine Information Center, which encompasses the dashboard display and its associated control buttons and switches. “Switch-1” denotes a […]

What Does Code B1208 Mean? DTC B1208 signifies that the vehicle’s Body Control Module (BCM), Instrument Cluster Control Module (ICCM), or a similar control unit responsible for interior electrical systems, has detected an electrical short-to-ground condition within the circuit of a specific user interface component identified as the “Switch-1 Assembly.” This assembly typically refers to […]
