LAND ROVER B — Body

Driver side, side collision sensor mounting failure

Brand: LAND ROVER
Type: B — Body
AI status
Completed
ready
Completed 100%
Page language: EN

Causes

  • Loose, missing, or damaged sensor mounting bracket or fasteners
  • Sensor dislodged or installed with incorrect orientation/angle
  • Corroded or damaged sensor connector or wiring harness
  • Faulty side collision sensor (internal failure)
  • SRS/airbag control module software or calibration error
  • Aftermarket repairs or bodywork that altered sensor position

Symptoms

  • Airbag/SRS warning lamp illuminated on dash
  • Possible SRS system warnings or service messages on scan tool
  • Seatbelt pretensioner or related restraint systems may be disabled
  • No obvious electrical faults other than SRS lamp
  • Vehicle recent body/seat repair or collision history

What to check

  • Read DTCs and freeze frame data with an OEM-capable scan tool; note status (current/stored/permanent)
  • Visual inspection of driver-side side collision sensor mounting point, bracket, and fasteners
  • Check connector engagement, condition of pins, locking tab, and evidence of corrosion or water ingress
  • Inspect harness routing for chafing, breaks, or repairs; gently wiggle harness while monitoring live data/DTCs
  • Verify sensor is the correct part number and installed with correct orientation per service manual
  • Check for related SRS codes that may indicate module or other sensor issues

Signal parameters

  • SRS control module should detect the sensor ID and report presence on CAN; no response = missing
  • Sensor internal self-test/passed flag reported via SRS network during ignition cycle
  • Supply voltage to sensor approx. battery voltage (9–16 V during cranking/normal); reference OEM values
  • Accelerometer/trigger channel baseline and noise values reported as expected; sudden short tests produce spikes
  • Circuit continuity/resistance to ground per service manual (measure with harness disconnected)
  • No short to battery or ground on sensor power and signal lines

Diagnostic algorithm

  1. Connect OEM scan tool, record DTC(s), freeze frame, and live SRS sensor list/status. Note whether code is current, pending, or permanent.
  2. Visually inspect sensor, bracket, and adjacent structure for damage, correct fastener torque, and correct orientation. Compare to service manual photos/diagrams.
  3. Inspect and backprobe connector: verify locking tab intact, pins not pushed back, no corrosion. With ignition ON, verify sensor supply and ground voltages per manual.
  4. Monitor live sensor data on scan tool while gently tapping and moving harness/mount; observe for loss of communication or absence of sensor ID.
  5. If wiring suspect, perform continuity and resistance checks between sensor connector and SRS control module; repair any open/shorted circuits.
  6. If connector, wiring, and mount are good but sensor still faults, swap with known-good sensor (if available) or replace sensor and reuse original bracket only if undamaged and correctly aligned.
  7. After repair or replacement, clear codes with scan tool and run OEM SRS self-test and any required sensor alignment/calibration procedures. Verify no new codes and that SRS lamp extinguishes.
  8. If DTC persists after sensor/connector/harness checks, inspect/replace mounting bracket or body anchors and repeat calibration. If still present, consider SRS control module diagnosis per OEM procedures.

Likely causes

  • Mounting bolt(s) loosened during seat removal or body repair
  • Sensor bracket cracked or deformed after an impact or crash repair
  • Connector not fully seated or retaining clip broken
  • Sensor replaced with incorrect part or installed rotated
  • Wire chafing or pin corrosion at sensor connector

Fault status

⚠️ Status
SRS control module reports driver-side side collision sensor mounting fault — sensor missing/not within expected orientation or failing self-test. DTC may be stored as current or permanent until repair and OEM self-test/calibration are completed.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1.0-3.0 hours
