DTC Code C161E – 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 electric pump relay circuit. This symptom is often linked to the relay being stuck, affecting the ABS functionality.</li> <li><a href="/problems/engine-warning-light-on"><b>Engine Light ON</b></a>: The Engine Light or Service Engine Soon warning light is activated, suggesting a malfunction in the electric pump relay circuit. This symptom is associated with the relay being stuck, which may impact the vehicle's overall performance.</li> </ul>

<ul><li>The electric pump relay may be faulty, causing the circuit to remain stuck and not function properly.</li><li>An open or shorted harness in the electric pump relay can disrupt the circuit's operation.</li><li>Poor electrical connections in the electric pump relay circuit can lead to intermittent or failed operation.</li><li>A malfunctioning All Wheel Control (AWC) ECU can send incorrect signals, affecting the relay's performance.</li><li>The electric pump itself may be defective, leading to improper relay circuit function.</li></ul>

<ul> <li><b>Initial Inspection</b>: Check the electric pump relay for any visible signs of damage or corrosion. Ensure that the relay is properly seated in its socket.</li> <li><b>Check Relay Operation</b>: Use a multimeter to test the relay's operation. Verify that the relay is receiving the correct voltage and is functioning as expected.</li> <li><b>Inspect Wiring and Connectors</b>: Examine the wiring and connectors associated with the electric pump relay circuit for any signs of wear, damage, or loose connections.</li> <li><b>Test Electric Pump</b>: Ensure the electric pump itself is not malfunctioning. Test the pump's operation by directly supplying power to it and observing its response.</li> <li><b>Check Control Module</b>: Inspect the control module that manages the electric pump relay circuit. Ensure it is functioning correctly and sending the appropriate signals.</li> <li><b>Perform System Reset</b>: After repairs, clear the DTC code and perform a system reset. Test drive the vehicle to ensure the issue does not reoccur.</li></ul>

<p>The DTC code C161E indicates a <b>critical</b> issue with the Electric Pump Relay Circuit System being stuck. This can lead to severe consequences such as <ul><li>overheating of the electric pump</li><li>potential failure of the hydraulic system</li><li>increased risk of vehicle breakdown</li></ul>. Immediate attention is required to prevent further damage and ensure vehicle safety.</p>
