B2367

Power Sliding Door Override Switch Input Ckt Short to Gnd

Body Chassis/Safety Door Control 🟢 Low — Fix at next service ✅ Safe to Drive
💬

What This Actually Means

In plain language — no jargon

The power sliding door's override switch circuit is shorted to ground, preventing the ECU from properly reading the switch signal. Think of it like a broken light switch that's stuck in the 'on' position—the system can't tell if you're actually pressing it.

How Your ECU Detects This

Technical sensor logic and voltage thresholds

The ECU monitors voltage on the override switch input circuit, expecting a high signal when the switch is open and a low signal when pressed. A short to ground keeps the signal permanently low, making the ECU unable to detect switch activation. The module uses voltage thresholds to distinguish between a valid switch press and a circuit fault.

Voltage & Parameter Thresholds

ParameterNormal RangeFault Condition
Override Switch Input Voltage 5V (open), <0.5V (pressed) Continuously <0.5V or shorted
Circuit Resistance >10kΩ (open), <1kΩ (closed) <500Ω (short to ground)

Diagnostic & DIY Fix Guide

Check these in order — from cheapest to most complex
1
Wiring harness connector
Inspect and reseat the override switch connector at the door latch assembly for corrosion or loose pins.
2
Override switch assembly
Replace the faulty override switch if continuity testing shows it is stuck closed or shorted.
3
Wiring and insulation
Repair or replace damaged wire insulation in the override switch circuit harness between the door and body module.

When to See a Professional Mechanic

Not all fault codes are safe to DIY

Code B2367 is a low-severity fault. Your vehicle is generally safe to drive to a workshop for diagnosis. However, do not ignore it indefinitely — low-severity codes often indicate developing problems that become expensive if neglected. Book a diagnostic appointment within 2–4 weeks. If you notice any additional symptoms (rough running, power loss, unusual smells), treat it as higher priority.

Safety note: OBD-II codes identify the system or circuit where a fault was detected — they do not always identify the exact failed component. A professional mechanic using live sensor data will diagnose the root cause more accurately than replacing parts based on the code alone.

How to Clear Code B2367

What happens after you fix the fault

Once the fault is repaired, B2367 can be cleared using any OBD-II scanner. Connect the scanner, navigate to "Clear Codes" or "Erase DTCs," and confirm. The check engine light turns off immediately.

The code will return if the root cause was not actually fixed. The ECM re-detects the fault within 1–3 drive cycles and sets the code again.

✅ Safe to Clear When
  • Fault has been diagnosed and repaired
  • You want to confirm the repair worked
  • Code appeared after a sensor was cleaned
⚠️ Do Not Clear When
  • Preparing for an emissions/PUC test
  • Root cause is still undiagnosed
  • Check engine light is flashing
Emissions test note: Clearing codes resets OBD readiness monitors. Most vehicles need 50–100 km of mixed driving before monitors complete. Do not clear codes immediately before an emissions or PUC inspection.
