DTC Code B1825 – What does this code mean?

<ul> <li><a href="/problems/engine-warning-light-on"><b>Engine Light ON</b></a>: The engine light or service engine soon warning light illuminates on the dashboard, indicating a potential issue with the driver seat recline position sensor circuit.</li> <li><b>Driver Seat Malfunction</b>: The driver seat may not recline or adjust properly, which can be linked to a short to ground in the recline position sensor circuit.</li> <li><b>Erratic Seat Movement</b>: The driver seat may move erratically or unexpectedly, potentially due to a short circuit affecting the sensor's operation.</li> </ul>

<ul><li>The driver seat recline motor may be faulty, causing incorrect position readings.</li><li>An open or shorted harness in the driver seat recline motor can disrupt the circuit.</li><li>Poor electrical connections in the driver seat recline motor circuit can lead to signal loss or interference.</li><li>The driver seat memory control module might be malfunctioning, affecting the seat position sensor readings.</li></ul>

<ul> <li><b>Initial Inspection</b>: Inspect the driver seat recline position sensor and its wiring for any visible damage or disconnection. Ensure the connectors are securely attached and free from corrosion.</li> <li><b>Check for Short to Ground</b>: Using a multimeter, measure the resistance between the sensor circuit and ground. A low resistance reading indicates a short to ground. Trace the wiring to identify any points of contact with the vehicle chassis.</li> <li><b>Inspect Wiring Harness</b>: Examine the wiring harness for any signs of wear, chafing, or pinching that could cause a short to ground. Pay special attention to areas where the harness passes through metal components.</li> <li><b>Test the Sensor</b>: Disconnect the sensor and test its resistance to ensure it is within the manufacturer's specifications. Replace the sensor if it is faulty.</li> <li><b>Check Control Module</b>: Inspect the control module for any signs of damage or malfunction. Ensure that the module is receiving the correct voltage and ground signals.</li> <li><b>Perform a System Reset</b>: After repairs, clear the DTC code and perform a system reset. Test the seat recline function to ensure proper operation and verify that the code does not return.</li></ul>

<p>The DTC B1825(02) indicates a <b>critical</b> issue with the driver seat recline position sensor circuit shorting to ground. This can lead to <ul><li>improper seat positioning</li><li>potential safety hazards during a collision</li></ul>. Immediate attention is required to prevent <b>serious injury</b> risks due to compromised seat functionality. Delaying repair could result in <b>increased danger</b> to the driver.</p>
