DTC Code C1008 – What does this code mean?

<ul> <li><b>Anti-Lock Brake System (ABS) Warning Light ON</b>: The ABS warning light illuminates when the brake fluid level circuit detects a high signal. This could indicate an issue with the brake fluid level sensor or a wiring problem.</li> <li><b>Engine Light ON (or Service Engine Soon Warning Light)</b>: The engine light or service engine soon warning light may turn on due to the brake fluid level circuit high signal. This can be caused by a malfunctioning brake fluid level sensor, faulty wiring, or a problem within the ABS control module.</li> </ul>

<ul><li>The brake fluid level sensor may be malfunctioning, leading to incorrect readings.</li><li>An open or shorted harness in the brake fluid level sensor can disrupt the signal transmission.</li><li>Poor electrical connections in the brake fluid level sensor circuit can cause intermittent or faulty signals.</li></ul>

<ul> <li><b>Initial Inspection</b>: Check the brake fluid level in the reservoir. Ensure it is within the recommended range. If low, refill with the appropriate brake fluid and inspect for leaks.</li> <li><b>Visual Inspection of Wiring</b>: Inspect the wiring and connectors related to the brake fluid level sensor for any signs of damage, corrosion, or disconnection.</li> <li><b>Sensor Voltage Check</b>: Using a multimeter, measure the voltage at the brake fluid level sensor. Compare the readings with the manufacturer’s specifications to determine if the sensor is functioning correctly.</li> <li><b>Continuity Test</b>: Perform a continuity test on the wiring harness from the brake fluid level sensor to the control module to ensure there are no open circuits.</li> <li><b>Control Module Inspection</b>: Check the control module for any stored codes or malfunctions that could be affecting the brake fluid level circuit. Clear any codes and retest the system.</li> <li><b>Sensor Replacement</b>: If all previous steps are completed and the issue persists, replace the brake fluid level sensor and recheck the system for proper operation.</li></ul>

<p>The DTC code C1008 indicates a high circuit issue in the brake fluid level sensor. This is a <b>critical</b> issue as it directly affects the braking system's performance.</p><ul><li>Immediate action is required to inspect and repair the brake fluid level sensor circuit.</li><li>Failure to address this can lead to brake failure, posing a significant safety risk.</li></ul>
