Causes
- Damaged or disconnected central frontal impact classification sensor
- Corroded or loose connector at sensor or airbag control module
- Broken, shorted or open wiring between sensor and SRS/airbag ECU
- Water intrusion around windshield area or sensor connector
- Faulty airbag control module or sensor electronics
- Intermittent CANbus/communication fault or software issue
Symptoms
- SRS/Airbag warning lamp illuminated on dash
- Possible disablement of airbag deployment logic or related restraint functions
- Related diagnostic trouble codes stored in SRS module
- Possible warning messages on cluster about service required
- Occasional loss of other related functions if communication bus affected (e.g., lighting sensor input)
What to check
- Read all SRS and body module codes with a compatible diagnostic scanner; record freeze frame and related codes
- Visually inspect windshield area, sensor mounting, and harness for damage or water ingress
- Inspect connectors for corrosion, bent terminals, or poor engagement
- Check wiring continuity and for shorts to battery and ground between sensor and SRS module
- Verify reference voltage, ground integrity and signal waveform (backprobe per service manual)
- Check CANbus integrity if sensor communicates over network (check for other module communication faults)
Signal parameters
- Reference voltage typically ~5 V (verify with service manual for exact value before testing)
- Signal voltage should vary per sensor type (0–5 V range) or produce a CANbus message — confirm expected waveform with manufacturer specs
- Battery supply voltage (VBatt) should be stable at ~12 V with key on during tests
- Good chassis/body ground continuity at sensor mount
- No short to ground or battery on signal/reference circuits
Diagnostic algorithm
- Retrieve the full DTC list and freeze frame data with an OEM-capable scan tool and note any related codes.
- Follow SRS safety procedure: disable vehicle battery (negative terminal) and wait the manufacturer-specified time before accessing SRS components.
- Perform a visual inspection of the windshield-mounted sensor, bracket and harness for physical damage, moisture, or loose connectors.
- Reconnect battery and with the scanner connected, backprobe the sensor connector to verify reference voltage, ground and signal presence per the service manual. Compare readings to OEM specifications.
- Check continuity and insulation of harness between sensor and airbag control module. Repair any open or short circuits found.
- If wiring and connectors are good, swap or bench-test the suspect sensor if a known-good unit or test procedure is available from the manufacturer.
- If sensor tests OK, check SRS/airbag control module operation and software level; reflash or replace module only if confirmed faulty per OEM diagnostics.
- After repairs, clear codes, perform SRS system self-tests with the scan tool and verify no reoccurrence of B1006. Re-enable vehicle and perform any required calibration/initialization steps.
- If intermittent, perform flex/wiggle tests of harness while monitoring live data to reproduce the fault before finalizing repairs.
Likely causes
- Corroded/wet connector at the windshield-mounted sensor
- Open or short in the sensor signal or reference wiring
- Failed central impact classification sensor
- Faulty airbag/SRS control module or corrupted software
- Poor grounding or intermittent connector contact
Fault status
Status
Frontal impact classification sensor (central) fault — communication/signal or high-beam/windshield sensor input anomaly detected. Service SRS system.
Repair difficulty: Hard
Diagnostic time: 1-3 hours
