What Does Code C1217 Mean? The diagnostic trouble code C1217 signifies an electrical short to ground detected within the control circuit for the Right Front (RF) Anti-lock Braking System (ABS) inlet valve coil. This code is specifically monitored and set by the ABS Control Module (often integrated within the Hydraulic Control Unit, HCU, or as […]

What Does Code C1218 Mean? DTC C1218 translates to “Lamp ABS Warning Output Circuit Failure.” This code indicates that the Anti-lock Braking System (ABS) control module, often referred to as the Electronic Brake Control Module (EBCM) or Hydraulic Control Unit (HCU), has detected an electrical malfunction within the dedicated circuit responsible for illuminating the ABS […]

What Does Code C1219 Mean? The diagnostic trouble code C1219 indicates an open circuit condition detected within the output pathway responsible for illuminating the Anti-lock Brake System (ABS) warning lamp on the vehicle’s instrument cluster. This code is typically set by the ABS Control Module (also known as the Electronic Brake Control Module or EBCM). […]

What Does Code C1220 Mean? The diagnostic trouble code C1220, designated as a Chassis (C) code, specifically indicates an electrical fault within the Anti-lock Brake System (ABS) module’s control circuit for the ABS warning lamp. The description “Lamp ABS Warning Output Circuit Short To Battery” signifies that the Electronic Brake Control Module (EBCM), often integrated […]

What Does Code C1221 Mean? DTC C1221 signifies an electrical fault within the output circuit responsible for illuminating the Anti-lock Braking System (ABS) warning lamp on the vehicle’s instrument cluster. Specifically, the Electronic Brake Control Module (EBCM), also often referred to as the ABS module, has detected a persistent short circuit to ground within this […]

What Does Code C1222 Mean? DTC C1222 indicates a Wheel Speed Mismatch detected by the Anti-lock Brake System (ABS) control module, which then communicates this fault to the Powertrain Control Module (PCM) or Engine Control Module (ECM) and other integrated vehicle stability systems. This code is set when the ABS module identifies an illogical or […]

What Does Code C1223 Mean? Diagnostic Trouble Code (DTC) C1223 indicates a malfunction within the brake warning lamp output circuit, specifically as monitored by the Anti-lock Brake System (ABS) module or Electronic Brake Control Module (EBCM). Unlike powertrain codes (P-codes), C1223 is a chassis code, meaning it pertains to vehicle systems outside of the engine […]

What Does Code C1224 Mean? DTC C1224, “Lamp Brake Warning Output Circuit Open,” indicates that the Anti-lock Braking System (ABS) module has detected an open circuit condition in the electrical pathway responsible for illuminating the brake warning lamp in the vehicle’s instrument cluster. The ABS module, often integrated with Vehicle Stability Control (VSC) and Traction […]

What Does Code C1225 Mean? DTC C1225 indicates a detected fault within the Lamp Brake Warning Output Circuit, specifically a Short To Battery condition. This diagnostic trouble code is typically set by the Electronic Brake Control Module (EBCM), Powertrain Control Module (PCM), or Body Control Module (BCM), depending on the vehicle’s specific electronic architecture. The […]

What Does Code C1226 Mean? DTC C1226 signifies a detected short-to-ground condition within the output circuit designated for the brake warning lamp on the vehicle’s instrument cluster. This code is typically set by the Brake System Control Module (BSCM), which is commonly integrated into the Anti-lock Brake System (ABS) module, Vehicle Stability Control (VSC) module, […]
