Diagnostic Guide for OBD-II Code B1060

Important Notes

• OBD-II trouble codes are organized into P (Powertrain), B (Body), C (Chassis), and U (Network) categories. This structure is described in the general OBD-II references. B1060 is a "B" code, i.e., a Body-system diagnostic code. The exact definition of B1060 is OEM-specific and is not universal across all makes/models. Therefore, always obtain the precise OEM definition from the manufacturer's service information before performing repairs.
• The broader OBD-II framework uses these codes to indicate abnormal conditions detected by on-board controllers, which may affect system function or emissions readiness.
• For standard code naming and categorization, GitHub repositories and references typically align with the same P/B/C/U structure, with B codes representing body-electrical/body-system concerns. Use OEM definitions as the authority for the exact B1060 meaning.

What you can expect with B1060 (symptom patterns)
Because B1060 is OEM-specific, symptoms will vary by vehicle and the body-system affected. Common user-complaint themes that can accompany body (B) codes include:

• Interior/auxiliary lighting issues (dash/clusters or interior lights flicker or stay on)
• Door/lock or latch warning indicators (doors reporting open/ajar or failure to lock/unlock properly)
• Seat-related or occupant-detection concerns (seat occupancy sensor, seat heater, or seat adjustment features)
• Airbag/SRS indicators may be involved if the body module coordinates occupant safety systems (note: airbags have their own coding families; an associated B-code may appear in some models)
• General body-control anomalies such as failed switches, faulty sensors, or intermittent body-control module (BCM) communications
• Note: The above are generic symptom patterns derived from typical body-code behavior and user-reported issues; the exact symptom set for B1060 depends on the OEM definition.

Diagnostic Approach

1) Confirm and define

• Use an OBD-II scanner to confirm that B1060 is stored and to read any related codes (e.g., additional B-codes, or U/Z codes). Record the exact definition given by the OEM service information for B1060 on this vehicle.
• Retrieve freeze-frame data (engine-off, key on, vehicle speed, etc.) and any recent drive cycle data to understand the condition under which the fault occurred.
• If available, pull any OEM service bulletin or dealer diagnostic notes for B1060 on this vehicle.

2) Assess symptom context and scope

• Note when the condition occurs (during locking/unlocking, door opening, seat movement, ignition on, etc.).
• Determine if the symptom is intermittent or constant.
• Check for any other stored trouble codes (P, C, U codes) and consider whether multiple systems are affected.

3) Visual inspection and basic integrity checks

• Inspect the affected body-area(s) for obvious faults:
  • Wiring harnesses, connectors, and grounds in the door, seat, interior panels, or other body areas implicated by the OEM definition.
  • For door- or latch-related B-codes: door hinges, door-actuator wiring, and door switch connectors; check for bent pins, corrosion, loose grounds.
  • For seat/occupant-detection-related B-codes: seat wiring (under seat carpets), connectors, and any seat electronics; inspect for moisture or debris.
  • For lighting/grouped-bodies issues: inspect interior/exterior lighting harnesses and ground points.
• Re-seat all connectors involved in the suspected circuit(s) and inspect for bent or damaged pins.

4) Electrical power and grounding checks

• With a DVOM (digital volt-ohm meter) or equivalent:
  • Verify battery voltage at the relevant power-supply pins (watch for variation with ignition on/off).
  • Check ground continuity from the body circuit/BCM to chassis/body ground.
  • Look for corrosion, high resistance, or intermittent grounding that could cause intermittent codes.
• If the OEM definition points to a particular module (e.g., BCM or a body-systems module), verify that module's power and ground rails are within specification.

5) Circuit testing and functional checks

• Use the vehicle's service information (wiring diagrams, pinouts, and test procedures) to identify:
  • Which pins supply power to the implicated circuit and which pins are grounds.
  • Resistor networks, switch inputs, or sensor lines that feed the body module.
• Perform targeted continuity and resistance checks where appropriate:
  • Check for open or short circuits to power, to ground, or to other circuits in the same harness.
  • Check for short-to-battery or short-to-ground conditions that could trigger faults.
• If the OEM procedure calls for it, perform a functional test sequence (operate the affected switch, latch, sensor, or actuator) and observe whether the control module responds correctly (LED indicators, message prompts, or expected subsystem behavior).

6) Component and subsystem testing

• If the OEM definition identifies a specific component (e.g., a door switch, seat occupancy sensor, or a particular actuator), test or bench-test that component if feasible.
• Replace defective components as indicated by OEM diagnosis; ensure connectors are clean and properly seated after replacement.

7) BCM/ECU considerations

• If the OEM suggests a body-control module issue (BCM) or a related body controller, evaluate:
  • Firmware/software status and version (if OTA or service-toolable).
  • Whether there are multiple related DTCs that point to a common module or communication path.
  • The possibility of ECU or BCM reset requirements after repair or part replacement.

8) Post-repair verification

• Clear the codes and run a vehicle drive cycle to verify that B1060 (and any related codes) do not return.
• Confirm the associated symptom is resolved under typical operating conditions.
• If the code returns, re-check all prior steps and consider OEM service procedures that may involve re-flashing, reprogramming, or module replacement.

Probable Causes

Note: The exact OEM-specific cause for B1060 will depend on the vehicle, but typical body-code failure modes tend to follow these patterns. These percentages are approximate, and are not drawn from NHTSA complaint data (which was not available ).

• Wiring harness damage, loose or corroded connectors, or poor grounds: ~40%
• Faulty switch, sensor, or actuator in the implicated body circuit (e.g., door switch, occupant sensor, or related input device): ~25%
• Body Control Module (BCM) or related body module fault or software issue: ~15%
• Power supply or battery/ground instability affecting the body circuit: ~10%
• Intermittent condition due to moisture, corrosion, or vibration in the harness or connectors: ~10%
• Important caveat: Exact distribution depends on the vehicle model and the OEM definition of B1060. Always confirm with OEM service information for precise root-cause prioritization.

Safety Considerations

• If the B1060 code could affect airbag/SRS functions per OEM definitions, follow appropriate safety precautions. Do not perform high-energy tests on suspected airbag circuits; refer to official SRS service procedures.
• Disconnect or disable high-voltage circuits only following proper procedures and with appropriate PPE if the vehicle uses HV systems.
• When inspecting connectors and harnesses, avoid creating new shorts or signs of damage; take care around battery terminals and power rails.

Practical example workflow (quick-reference)

• Step 1: Confirm B1060 definition from OEM service information; note any related codes.
• Step 2: Visual inspection of the implicated body area(s); reseat connectors.
• Step 3: Verify power/ground integrity to the implicated circuit/module.
• Step 4: Perform wiring checks as per OEM diagrams; test suspected sensors/switches.
• Step 5: If feasible, replace the faulty component or repair the wiring; re-test.
• Step 6: Clear codes and drive-cycle the vehicle; confirm no recurrence.
• Step 7: If code recurs, escalate with OEM-specific diagnostic procedures and consider BCM/software reprogramming if indicated.
