MITSUBISHI B — Body

Front ABG safing G sensor open

Page language: EN

Causes

  • Open or disconnected wiring/harness to front G (safing) sensor
  • Loose, corroded or damaged connector at the sensor or SRS ECU
  • Failed front G (safing) sensor
  • Faulty SRS (airbag) control module or connector
  • Previous deployment or impact damage with unaddressed wiring/sensor damage
  • Water intrusion or contamination at sensor or connector

Symptoms

  • SRS/AIRBAG warning lamp illuminated on instrument panel
  • Possible disablement of airbag deployment circuit (faulted safing sensor)
  • Stored B1467 code in SRS memory
  • No other obvious drivability symptoms

What to check

  • Confirm battery voltage is stable (12V+) and record stored SRS codes with scanner
  • Visual inspection of front G-sensor connector, wiring harness and routing for damage, corrosion, or water
  • Wiggle/strain-relief test on wiring and connectors while monitoring code or live data
  • Measure continuity between sensor connector and SRS ECU connector for expected pins
  • Measure sensor circuit voltage/resistance per factory data (check for open circuit)
  • Inspect for prior crash repairs or deployed airbags that might have damaged wiring

Signal parameters

  • Expected: sensor circuit should show continuity (finite resistance) between sensor and ECU; open = infinite/very high resistance
  • Expected: reference supply present at sensor connector (typically a low-voltage reference from SRS ECU; check factory spec)
  • Fault indication: sensor line at or near 0V or battery voltage with no expected switching when tapped
  • Live-data: G-sensor should report changing values when the vehicle or sensor is physically moved (consult service manual for units/range)

Diagnostic algorithm

  1. Read and record all stored SRS codes and freeze frame data; note any related codes.
  2. Visually inspect the front G-sensor, connector, and harness for damage, corrosion, water, or signs of previous repairs.
  3. Verify battery voltage and ground integrity; some SRS tests require stable voltage.
  4. With ignition ON (follow manufacturer safety procedure for SRS), check for proper reference voltage/signal at the sensor connector using a multimeter or scan tool live data.
  5. Check continuity between the sensor connector pins and the SRS ECU connector pins. Replace/repair any open wires or poor terminations.
  6. If wiring and connectors are good, measure sensor resistance or output per factory specifications; if the sensor shows an open internal circuit, replace the sensor.
  7. If sensor and wiring check OK but code persists, inspect SRS ECU connector and pin condition. Repair harness or connectors as needed.
  8. If wiring, connector, and sensor are confirmed good, suspect SRS ECU input fault—consult technical service information before replacing ECU.
  9. After repairs, clear codes, perform SRS system self-check, and verify no reoccurrence. Always use an appropriate scan tool and follow manufacturer SRS safety procedures (disable battery, wait recommended time) when servicing components.

Likely causes

  • Broken/crushed wire in loom to front G-sensor (open circuit)
  • Pin pushed out, bent or corroded in sensor connector
  • Sensor internal failure (open internal circuitry)
  • Poor ground or intermittent connector contact causing open detection
  • Faulty SRS ECU input circuit (less common)

Fault status

⚠️ Status
Open circuit detected in front ABG (airbag) safing G-sensor circuit. The SRS control unit is not receiving a valid signal from the front safing G-sensor, causing an SRS fault and illumination of the airbag warning lamp.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 0.5-2 hours
