Is it safe to drive?

Caution — diagnose the relay circuit promptly B2064 indicates that the power-controlled pedals disable-relay circuit has an electrical fault. If pedal assist and pedal response remain normal, the vehicle can be driven cautiously, but the affected system should not be relied upon until repaired. Stop safely if pedal travel, assist, or vehicle response becomes inconsistent.

Typical symptoms

B2064 is stored as a current, pending, or permanent body-control code
A system warning message or warning lamp may illuminate with B2064 present
The power-controlled pedal assist may fail to engage or disable as commanded
Pedal feel, travel, or assist may change unexpectedly while B2064 is active
The disable-relay fault may occur intermittently and return after the vehicle is restarted
The vehicle may otherwise operate normally while the B2064 fault remains stored

Common causes

A failed power-controlled pedals disable relay with an open coil, defective contacts, or an incorrect resistance reading
Corrosion, backed-out terminals, or water intrusion in the disable-relay connector
Chafed or damaged wiring, an open circuit, or high resistance in the relay control harness
A blown circuit-protection fuse or an unstable ground connection associated with the relay circuit
A short to battery voltage or ground in the relay control line
An internal driver fault in the power-controlled pedal module or body control module

How to diagnose with an OBD scanner

Confirm B2064 and record the test conditions Connect an OBD2 scanner, such as an ELM327 adapter with AIScanAuto, and read stored, pending, and permanent codes. Confirm that B2064 is present, record any freeze-frame data, and note whether the relay fault occurred during startup, pedal operation, or a system reset. Do not erase the code before preserving this information.
Locate and inspect the disable-relay circuit Use the vehicle wiring diagram to identify the power-controlled pedals disable relay, its connector, related fuse, and ground. Inspect the relay socket and connector for corrosion, bent pins, backed-out terminals, water damage, and green electrical contamination. Follow the harness closely for chafing near hinges or moving pedal components.
Check the fuse, ground, relay, and wiring With the ignition off as specified by the manufacturer, check the circuit-protection fuse and ground continuity. Test the relay coil and terminals with a multimeter against the service specifications rather than generic resistance assumptions. Check the control wiring for opens and shorts if the relay and connectors pass visual inspection.
Compare commanded and measured relay operation If the scanner supports body-module testing, command the disable relay and observe the reported state while measuring voltage at the relay or control-module connector. An incorrect output despite a correct command points toward the relay, harness, or module driver. Generic scanners may not command this function, so use the wiring diagram and manufacturer procedure when live testing.
Repair and verify the B2064 condition Repair the failed fuse, ground, connector, damaged wire, or relay using the correct replacement. If all external checks pass, perform module-level diagnosis before condemning the controller. Clear B2064 with the OBD2 scanner, confirm the relay enables and disables the power-controlled pedal function, and verify that the code does not return during a complete pedal operating cycle.

Approximate repair cost

Estimated independent-shop cost for diagnosing and repairing B2064 is roughly USD $180–$800. The total depends on whether the fault is a relay, fuse, connector, wiring repair, or a power-pedal control module. These figures are estimates only, not verified quotes, and prices vary by region, labor rate, and parts availability.

Common questions

Does B2064 prove that the disable relay itself is defective?

No. B2064 identifies a fault in the power-controlled pedals disable-relay circuit, which can also involve wiring, connectors, a fuse, a ground, or the control module.

Is it safe to drive a vehicle with B2064 stored?

Driving may be possible if pedal feel and operation remain normal, but the affected power-controlled pedal function should be diagnosed promptly and should not be relied upon.

What should be checked first when diagnosing B2064?

Start with the relay connector, related fuse, ground, and visible harness damage, then use a wiring diagram and meter to verify the relay and control circuit electrically.

Why might B2064 return after the relay is replaced?

The code can return if the actual fault is a shorted control wire, poor ground, damaged connector, intermittent harness problem, or an internal fault in the pedal or body control module.

B2064 — B2064 — Manufacturer Controlled DTC: Causes, Symptoms & Fix

When the powertrain or body control module detects a problem in the vehicle's electrical system that doesn't match factory expectations, it logs trouble code B2064. This particular DTC falls into the "B" body category, which covers everything outside the engine and transmission — things like power windows, door locks, interior lighting, wipers, and related actuators. The module constantly monitors these circuits against programmed thresholds, and if a reading falls outside acceptable limits over one or more drive cycles, B2064 gets set and a freeze frame snapshot is saved. That snapshot records engine speed, load, coolant temperature, and vehicle speed at the exact moment the fault occurred, giving you a head start on pinpointing the problem.

The vehicle's body control module serves as the central hub for most comfort and convenience features. It processes inputs from switches and sensors, then commands outputs to motors and lights accordingly. When communication between the BCM and a component breaks down — whether through a bad connection, failed component, or wiring issue — the module recognizes the discrepancy and stores B2064. This code alone doesn't tell you which specific circuit failed, but it confirms the problem lives in the body electrical system rather than the drivetrain.

Common Symptoms of B2064

The affected electrical function typically stops working or behaves erratically. Depending on which circuit triggered the code, you might lose power door locks, window operation, exterior lights, windshield wipers, or other body-controlled features. In most cases, the engine runs normally — B2064 doesn't directly affect powertrain operation. A dashboard warning light usually accompanies the fault, though it may be a general "check vehicle" indicator rather than a specific system light. Intermittent operation is common early in the failure sequence before the problem becomes constant.

What Causes B2064?

A blown fuse or malfunctioning relay often creates the fault signal the module interprets as B2064. These are the simplest and most affordable culprits to address. A failed switch, motor, or actuator within the affected circuit can also trigger the code when the module no longer receives expected feedback. Wiring damage in high-flex areas like door jambs and tailgate hinges exposes conductors to breakage and short circuits. Corroded or loose connectors prevent clean electrical communication and may set intermittent faults. Finally, the body control module itself can fail, though this is less common than peripheral component issues.

How to Diagnose B2064

Begin by connecting an OBD2 scanner and confirming B2064 is stored in the system memory. Record the associated freeze frame data before clearing anything — those engine conditions tell you whether the fault occurred at idle, under load, or during specific driving maneuvers. Review any other stored trouble codes as well; related P-codes or C-codes often point directly to the failing component. Checking manufacturer technical service bulletins for your specific make, model, and model year can reveal known issues with software solutions or updated parts.

Perform a thorough visual inspection of the wiring harness and connectors tied to the suspected circuit. Look for damaged insulation, corrosion buildup, bent pins, or loose fits. With the key on and engine running, observe the live data parameters for the switch and motor involved — their voltage and current readings should respond predictably when you operate the controls. Pay special attention to flex points where wires bend repeatedly, particularly in door hinges and hatch openings. After clearing the code, complete a drive cycle that reproduces the conditions captured in the freeze frame, then verify B2064 does not return.

Repair Options and Costs

Address the most probable causes before committing to expensive replacements. If testing reveals a bad relay or fuse, installation runs $15 to $50 for parts with minimal labor. A faulty switch or actuator typically requires $120 to $450 for parts and professional installation, depending on the component's location and complexity. Wiring repairs involving solder splices, new connectors, or harness replacement generally cost $80 to $250 for materials and labor. When the body control module itself is diagnosed as faulty, replacement or reprogramming ranges from $300 to $900 including parts and dealer-level coding.

Can You Drive with B2064?

In most situations, B2064 poses no drivability concern — the engine and transmission operate independently of body system faults. However, consider the specific function affected before driving in challenging conditions. If exterior lighting or windshield wipers are involved, operate the vehicle only when visibility is good and weather permits. Central locking failures can leave doors unreliable, so park securely and consider manual lock mechanisms as a temporary workaround until repairs are completed.
