Introduction:
The B1710 diagnostic trouble code (DTC) indicates a problem within the circuit controlling the "front up" function of the driver's seat. Specifically, the vehicle's computer has detected an open circuit in this system. This means the electrical path that allows the seat to move upwards at the front is broken, preventing the switch from properly signaling the seat motor. This can lead to a frustrating situation where the driver is unable to adjust the seat to their desired position.

Switch replacement is generally straightforward. Module replacement often requires programming with a scan tool. |
| Estimated Repair Cost | Varies widely depending on the cause. Switch replacement: $50-$200. Motor replacement: $200-$500. Module replacement: $300-$1000+. | Labor costs can significantly increase the overall repair cost. Consider the cost of diagnostic fees if you take it to a professional. |
| Impact on Safety | Indirectly affects safety by impacting driver comfort and potentially affecting their ability to control the vehicle. | An uncomfortable driving position can lead to fatigue and reduced reaction time. |
| Module Programming | BCM/SCM replacement typically requires programming to match the vehicle's VIN and options. | Programming ensures the new module communicates correctly with other vehicle systems. This often requires specialized scan tools and software. |
| Fuse Identification | Consult the vehicle's owner's manual for the location of the seat power fuse. | A blown fuse could indicate a short circuit in the system. Replacing the fuse without addressing the underlying cause may result in it blowing again. |
Detailed Explanations:
Definition of B1710: This code precisely identifies that the vehicle's computer (either the Body Control Module or Seat Control Module) has detected an open circuit in the electrical path that controls the "front up" movement of the driver's seat. An "open circuit" means there's a break in the electrical connection, preventing the signal from the switch from reaching the seat motor.
Affected System: The driver's seat front up adjustment system is responsible for raising the front portion of the driver's seat. This adjustment is crucial for achieving optimal driving posture and comfort.
Potential Symptoms: The most obvious symptom is the inability to raise the front of the driver's seat. Other symptoms might include intermittent operation (sometimes working, sometimes not) or clicking sounds from the seat motor as it attempts to move.
Common Causes: Several factors can lead to an open circuit. Wiring problems (damaged or broken wires) are a frequent culprit. A faulty switch that isn't properly closing the circuit when activated is another common cause. A faulty seat motor itself might have an internal open circuit. Corrosion on connectors can also disrupt the electrical flow. Finally, the BCM or SCM itself could be malfunctioning, although this is less common.
Diagnostic Steps: A methodical approach is essential for diagnosing the B1710 code. Visual inspection is the first step, looking for any obvious damage to the wiring harness or connectors. Multimeter testing is used to check for voltage and continuity in the circuit. A scan tool can read DTCs and provide valuable data from the seat module. Reviewing the wiring diagram helps trace the circuit and identify potential problem areas.
Tools Required: A multimeter is essential for testing voltage and continuity. A scan tool is helpful for reading DTCs and accessing module data. A wiring diagram is crucial for tracing the circuit. Basic hand tools (screwdrivers, pliers, wire strippers) are needed for accessing components and making repairs.
Repair Procedures: Repairing the B1710 fault often involves addressing the underlying cause. Wiring repairs involve fixing damaged wires (soldering and insulation are important). A faulty switch needs to be replaced. A faulty motor requires replacement. Corroded connectors should be cleaned with electrical contact cleaner. In rare cases, the BCM or SCM might need replacement (which often requires programming).
Related DTCs: Other seat-related DTCs (B1700-B1799) or power window/door lock DTCs (B1200-B1299) might be present, indicating a broader electrical system issue.
System Components: The key components include the driver's seat, the front up switch, the seat motor, the wiring harness, connectors, and the Body Control Module (BCM) or Seat Control Module (SCM). The switch sends a signal to the BCM/SCM, which in turn activates the seat motor.
Testing Procedures (Detailed):
- Switch Testing: Disconnect the switch and use a multimeter set to continuity mode. Check for continuity between the terminals when the switch is activated in the "up" position. If there's no continuity, the switch is faulty.
- Motor Testing: Disconnect the motor connector. Carefully apply 12V DC directly to the motor terminals. If the motor doesn't run, it's likely faulty. Reverse the polarity to see if it runs in the opposite direction.
- Wiring Testing: Use a wiring diagram to identify the wires in the circuit. With the ignition off, use a multimeter to check for continuity between the switch connector and the motor connector. Also, check for voltage at the motor connector when the switch is activated (ignition on).
- Connector Testing: Visually inspect all connectors in the circuit for corrosion or damage. Clean any corroded connectors with electrical contact cleaner. Ensure the connectors are securely connected.
Component Location: The driver's seat and its associated wiring are located under the seat. The front up switch is usually on the side of the seat or in the door panel. The BCM/SCM location varies by vehicle manufacturer but is often under the dash or seat.
Potential for DIY Repair: The difficulty of the repair depends on your skills and the cause of the problem. Wiring repairs and switch replacement are often DIY-able for those with some experience. However, module replacement requires specialized tools and knowledge.
Estimated Repair Cost: Costs vary widely. Switch replacement might cost $50-$200. Motor replacement could be $200-$500. Module replacement can range from $300 to $1000 or more (including programming). Labor costs can significantly increase the overall repair cost.
Impact on Safety: While not a direct safety issue, an uncomfortable driving position can lead to fatigue and reduced reaction time, indirectly affecting safety.
Module Programming: BCM/SCM replacement typically requires programming to match the vehicle's VIN and options. This ensures the new module communicates correctly with other vehicle systems.
Fuse Identification: Consult your vehicle's owner's manual for the location of the seat power fuse. A blown fuse could indicate a short circuit.
