DTC Code C1417 – What does this code mean?

<ul> <li><a href="/problems/abs-light-is-on"><b>ABS Warning Light ON</b></a>: The Anti-Lock Brake System (ABS) warning light illuminates on the dashboard, indicating a potential issue with the ABS system. This can be linked to a high power supply voltage malfunction, which may affect the ABS module's performance.</li> <li><a href="/problems/engine-warning-light-on"><b>Engine Light ON</b></a>: The engine light, also known as the Service Engine Soon warning light, turns on. This symptom suggests a possible electrical issue, such as a high power supply voltage, which can impact various engine control systems.</li> </ul>

<ul><li>The charging system may be faulty, leading to an overvoltage condition that triggers the high power supply voltage malfunction.</li><li>A defective battery can cause voltage irregularities, resulting in the C1417 error code.</li><li>The Skid Control ECU, also known as the Brake Actuator Assembly, might be malfunctioning, causing incorrect voltage readings and triggering the error.</li></ul>

<ul> <li><b>Verify DTC Code</b>: Ensure the DTC C1417 is active and not a historical code. Clear the code and see if it returns after a test drive.</li> <li><b>Inspect Battery Voltage</b>: Measure the battery voltage with a multimeter. It should be between 12.4V and 12.7V with the engine off. If higher, check for overcharging.</li> <li><b>Check Alternator Output</b>: Start the engine and measure the alternator output. It should be between 13.5V and 14.5V. If higher, inspect the voltage regulator for faults.</li> <li><b>Examine Wiring and Connectors</b>: Inspect the wiring and connectors related to the power supply circuit for corrosion, damage, or loose connections.</li> <li><b>Test Power Supply Circuit</b>: Perform a continuity test on the power supply circuit to ensure there are no open or short circuits.</li> <li><b>Inspect Control Module</b>: Check the control module for any signs of damage or malfunction. Replace if necessary.</li> <li><b>Re-evaluate DTC Code</b>: After repairs, clear the DTC and perform a test drive to ensure the code does not return.</li></ul>

<p>The DTC code C1417 indicates a <b>High Power Supply Voltage Malfunction</b>. This is a <b>critical</b> issue as it can lead to severe electrical system failures, potentially affecting the vehicle's safety systems. <ul><li>Immediate attention is required to prevent further damage to the vehicle's electrical components.</li><li>Delaying repairs could result in complete electrical failure, posing significant safety risks.</li></ul></p>
