What Does Code C1166 Mean? DTC C1166 indicates an “Open Circuit” condition detected in the electrical circuit for the Rear Right (RR) Wheel Speed Sensor. This code is typically set by the Anti-lock Brake System (ABS) control module, which is often integrated into the Powertrain Control Module (PCM), Brake Control Module (BCM), or a standalone […]

What Does Code C1167 Mean? The diagnostic trouble code C1167 signifies an electrical fault within the Electronic Parking Brake (EPB) system, specifically indicating a Park Brake Actuator Assembly Switch Released Circuit Short to Ground. This code is typically set by the Electronic Parking Brake (EPB) control module, which may be a standalone unit or integrated […]

What Does Code C1168 Mean? The diagnostic trouble code C1168 signifies a Rear Right (RR) Wheel Speed Sensor Coherency Fault. This code is typically set by the Anti-lock Brake System (ABS) control module, which often communicates with or is integrated into the Powertrain Control Module (PCM) via the Controller Area Network (CAN) bus. The ABS […]

What Does Code C1169 Mean? DTC C1169, which translates to “ABS Fluid Dumping Exceeds Maximum Timing,” indicates a critical issue within the vehicle’s Anti-lock Braking System (ABS) module’s hydraulic control unit (HCU). This code signifies that the Electronic Brake Control Module (EBCM), often integrated with the HCU, has detected an abnormally prolonged pressure reduction phase […]

What Does Code C1170 Mean? Diagnostic Trouble Code (DTC) C1170 indicates a detected malfunction within the PRNDL (Park, Reverse, Neutral, Drive, Low) Switch circuit. This switch, often referred to as the Transmission Range Sensor (TRS), is a critical input device that communicates the selected gear lever position to the Powertrain Control Module (PCM) or Transmission […]

What Does Code C1172 Mean? DTC C1172 indicates a circuit failure related to the Park Brake Switch #1, signifying that the vehicle’s control module has detected an implausible or persistent “applied” state signal from this switch circuit. While C-codes typically pertain to Chassis systems, the specific control module monitoring this circuit can vary by manufacturer […]

What Does Code C1173 Mean? DTC C1173 indicates a “Park Brake Switch #1 Released Circuit Short to Ground.” This code is set by the vehicle’s control module, often the Body Control Module (BCM), Powertrain Control Module (PCM), or an Integrated Chassis Control Module, when it detects an unexpected electrical short to ground on the dedicated […]

What Does Code C1174 Mean? DTC C1174 indicates a circuit failure related to the secondary parking brake switch, often designated as “Switch #2,” being detected as “applied” or experiencing an electrical anomaly in its circuit. Modern vehicle systems, particularly those equipped with advanced chassis control modules such as the Anti-lock Braking System (ABS), Vehicle Stability […]

What Does Code C1175 Mean? DTC C1175 indicates a detected fault within the input circuit of the Left Rear (LR) Wheel Speed Sensor. The Anti-lock Brake System (ABS) control module, which may be integrated into the Powertrain Control Module (PCM), Body Control Module (BCM), or exist as a standalone unit, is responsible for monitoring the […]

What Does Code C1176 Mean? DTC C1176 signifies an open circuit condition detected within the Left Rear (LR) wheel speed sensor electrical circuit. This fault is primarily monitored by the vehicle’s Anti-lock Braking System (ABS) Control Module (also known as the Electronic Brake Control Module or EBCM). The ABS module continuously monitors the electrical characteristics, […]
