LAND ROVER B — Body

Unable to confirm the locked condition

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

Causes

  • Faulty lock actuator or solenoid
  • Faulty lock position sensor or switch
  • Open/shorted wiring or poor connector at actuator/sensor
  • Blown fuse or inadequate supply voltage
  • Body/door/central convenience module software fault or internal failure
  • CAN or LIN communication loss between modules

Symptoms

  • Door/boot/steering/gear lock will not reliably lock or unlock
  • Vehicle displays 'unable to confirm locked condition' or related message
  • Remote/key fob lock operation appears ineffective or intermittent
  • Security/immobilizer warnings or inability to arm vehicle
  • Unusual actuator noise (grinding or no sound) when locking
  • Interior lock switch does not change lock state

What to check

  • Read all stored DTCs and freeze frame data from all modules (BCM/CCM/IPC/IMM) and note occurrence conditions
  • Verify battery voltage (should be ~12–14.5 V) and good battery condition
  • Check related fuses and relays for the lock/central convenience circuits
  • Visual inspection of wiring and connectors at the affected lock actuator and module for corrosion, damage or loose pins
  • Attempt to reproduce failure and note which doors/locks are affected
  • Use scan tool to monitor lock request commands and lock position/feedback live data while operating the lock

Signal parameters

  • Supply voltage to actuator: battery voltage nominal ~12–14.5 V when engine off/running
  • Lock command signal: digital/diagnostic command from BCM over CAN or local switch signal (present when lock request issued)
  • Lock position feedback: discrete or analog sensor (typical states: 'locked' or 'unlocked'); expected change on command
  • Actuator current draw: brief surge during correct operation (higher or no current may indicate jam or motor fault)
  • CAN bus voltages: differential signals present and modules responsive; no bus errors
  • LIN/local serial lines: expected message/acknowledgement from door module when commanded

Diagnostic algorithm

  1. Verify: Confirm the customer complaint and capture conditions when the DTC sets. Check for any related DTCs in other modules.
  2. Battery & power: Measure and record battery/resting voltage. Check fuses and relays for the lock circuits.
  3. Reproduce & observe: With a scan tool, command lock/unlock and watch live data for lock request and lock position feedback.
  4. Inspect wiring: Visually inspect wiring harness and connectors at the affected lock and the controlling module. Wiggle test while commanding the lock.
  5. Measure signals: Probe supply, ground and feedback wires at the actuator during operation. Confirm proper voltage and switching.
  6. Actuator bench or direct test: If safe/possible, remove and bench-test actuator or apply battery power briefly to verify movement and current draw.
  7. Communications: Check CAN/LIN for errors and verify the controlling module is communicating. Repair any bus faults first.
  8. Mechanical check: Ensure latch/lock mechanism is not physically obstructed and is free-moving.
  9. Replace suspected failed component: Replace actuator, sensor or repair wiring only after confirming with tests.
  10. Clear codes & retest: Clear DTCs and perform several lock/unlock cycles. Road-test or cycle the system to confirm repair. If DTC returns, escalate to manufacturer technical bulletins or module reprogramming as required.

Likely causes

  • Defective lock actuator (most common)
  • Damaged or corroded connector/wiring to actuator or sensor
  • Lock position sensor failed or misaligned
  • Loss of module communication (CAN/LIN) preventing feedback
  • Low battery voltage or blown fuse feeding the lock circuit

Fault status

⚠️ Status
Control module cannot verify the lock is in the commanded (locked) state — lock feedback missing or invalid.
🟡 Repair difficulty: Medium
⏱️ Diagnostic time: 1-3 hours
