What Does Code B1209 Mean? DTC B1209 signifies a “EIC Switch-2 Assembly Circuit Failure.” This is a manufacturer-specific body code, typically indicating an electrical fault within the circuit of a specific switch assembly monitored by the Electronic Information Center (EIC) or a related Body Control Module (BCM). The EIC, often integral to the instrument cluster […]

What Does Code B1210 Mean? The diagnostic trouble code B1210 signifies an detected open circuit within the EIC Switch-2 Assembly. In automotive diagnostics, ‘B’ codes typically refer to Body Control Module (BCM) or related vehicle body electrical systems, rather than the core powertrain. The EIC, or Electronic Instrument Cluster (sometimes referred to as Engine Information […]

What Does Code B1211 Mean? DTC B1211 signifies a detected electrical fault within the “EIC Switch-2 Assembly” circuit, specifically indicating a “Short To Battery.” In automotive diagnostics, a ‘B’ prefix code denotes an issue related to the Body Control Module (BCM) or other body-related systems, rather than powertrain (P), chassis (C), or network (U) faults. […]

What Does Code B1212 Mean? DTC B1212 indicates a specific electrical fault within the vehicle’s cabin electronics, specifically identifying an “EIC Switch-2 Assembly Circuit Short To Ground.” The “EIC” typically refers to the Electronic Instrument Cluster or Engine Information Center, which serves as a central hub for driver controls and information display. The “Switch-2 Assembly” […]

What Does Code B1213 Mean? DTC B1213, “Anti-Theft Number of Programmed Keys Is Below Minimum,” indicates that the vehicle’s immobilizer system has detected that the number of legitimately programmed transponder keys registered to the vehicle is fewer than the manufacturer’s specified minimum threshold. This code is typically set by the Immobilizer Control Module (ICM), Body […]

What Does Code B1214 Mean? DTC B1214 signifies a diagnostic trouble code specifically indicating a fault within the running board lamp circuit. This is a manufacturer-specific B-code, typically pointing to an issue monitored and reported by the Body Control Module (BCM), General Electronic Module (GEM), or a similar accessory control module rather than the Engine […]

What Does Code B1215 Mean? DTC B1215 indicates a specific electrical fault within the running board lamp circuit, signifying a “Short to Battery.” This diagnostic trouble code is typically set by the Body Control Module (BCM) or a similar accessory control module responsible for exterior lighting and convenience features. The BCM monitors the voltage and […]

What Does Code B1216 Mean? DTC B1216 indicates that the vehicle’s Body Control Module (BCM) or Telematics Control Unit (TCU) has detected a short to ground condition within the electrical circuit dedicated to the Emergency and Road Side Assistance Switch. This circuit is an integral part of the vehicle’s telematics system, which may include features […]

What Does Code B1217 Mean? DTC B1217 indicates a detected malfunction within the horn relay’s coil control circuit. This code is typically set by a Body Control Module (BCM), Smart Junction Box (SJB), or an Integrated Central Control Module (ICCM), rather than the Powertrain Control Module (PCM), as it pertains to a body electrical function. […]

What Does Code B1218 Mean? Diagnostic Trouble Code (DTC) B1218 indicates a specific electrical fault within the horn relay coil control circuit, specifically a “Short to Vbatt” (Battery Voltage). This means the vehicle’s Body Control Module (BCM), or sometimes a dedicated Junction Box Module (JBM) or Smart Power Distribution Module (SPDM), has detected uncommanded battery […]
