What Does Code C1287 Mean? The diagnostic trouble code C1287 indicates a malfunction within the Booster Pedal Force Switch circuit. This chassis-related code, typically registered by the Electronic Brake Control Module (EBCM), Anti-lock Braking System (ABS) module, or Traction Control System (TCS) module, signifies that the control module has detected an electrical anomaly in the […]

What Does Code C1288 Mean? The diagnostic trouble code C1288 signifies a “Pressure Transducer Main / Primary Input Circuit Failure.” This chassis code (C-code) indicates that the Anti-lock Braking System (ABS) control module, or sometimes the Powertrain Control Module (PCM) or Vehicle Stability Control (VSC) module, has detected an electrical fault within the primary circuit […]

What Does Code C1289 Mean? DTC C1289 signifies a detected electrical fault or functional anomaly within the redundant or secondary input circuit of a pressure transducer, typically associated with the vehicle’s Electronic Brake Control Module (EBCM), also known as the Antilock Brake System (ABS) module or Vehicle Stability Control (VSC) module. In modern automotive braking […]

What Does Code C1400 Mean? The diagnostic trouble code C1400, “Traction Control Valve RF Circuit Failure,” indicates a detected electrical malfunction within the control circuit of the right front (RF) traction control solenoid valve. This code is typically set by the Electronic Brake Control Module (EBCM), also often referred to as the Anti-lock Brake System […]

What Does Code C1401 Mean? Diagnostic Trouble Code C1401 indicates an “Open Circuit” condition detected by the Anti-lock Braking System (ABS) or Vehicle Stability Control (VSC) module within the electrical circuit of the Right Front (RF) Traction Control Valve. This valve is a solenoid housed within the ABS Hydraulic Control Unit (HCU) responsible for modulating […]

What Does Code C1402 Mean? DTC C1402 signifies a detected Traction Control Valve RF Circuit Short To Ground. This code is issued by the Anti-lock Brake System (ABS) control module, which often integrates the Traction Control System (TCS) and Electronic Stability Control (ESC) functionality. The “RF” designation refers to the Right Front wheel. Within the […]

What Does Code C1403 Mean? DTC C1403 signifies that the Anti-lock Braking System (ABS) control module, often integrated with the Traction Control System (TCS) and Vehicle Stability Control (VSC) module, has detected an electrical fault indicative of a short circuit to battery voltage within the control circuit for the Right Front (RF) Traction Control Valve. […]

What Does Code C1404 Mean? DTC C1404 typically signifies a fault within the electrical circuit of the rear traction control valve, often specific to Toyota, Lexus, and similar manufacturer platforms. This code indicates that the Anti-lock Braking System (ABS) and Traction Control System (TCS) control module has detected an abnormal electrical condition in the circuit […]

What Does Code C1405 Mean? DTC C1405 signifies a detected electrical open circuit within the rear traction control valve circuit. This code is typically set by the Anti-lock Braking System (ABS) control module, which often integrates the Traction Control System (TCS). The TCS employs solenoid valves within the ABS Hydraulic Control Unit (HCU) or modulator […]

What Does Code C1406 Mean? Diagnostic Trouble Code C1406 signifies that the Anti-lock Braking System (ABS) or Traction Control System (TCS) module has detected an electrical short circuit to ground within the control circuit of the rear traction control valve. This specific valve is an electro-hydraulic solenoid located within the ABS/TCS Hydraulic Control Unit (HCU), […]
