Causes

Failed right front comfort solenoid (stuck, coil open or shorted)
Damaged or corroded connector at the solenoid
Broken or shorted wiring in the right front door harness
Blown fuse or faulty relay supplying the comfort circuit
Body Control Module (BCM) output fault or software issue
Mechanical binding in the door latch/actuator preventing operation

Symptoms

Right front door does not lock/unlock with central locking or remote
Right front door does not perform comfort-close/comfort-open actions
Clicking or no noise from the right front door when actuating locks
Warning message or indicator related to central locking/comfort system
Intermittent operation of right front door functions
Possible parasitic battery drain if solenoid stuck energized

What to check

Scan vehicle and read freeze frame and related DTCs; note history and conditions
Visual inspection of right front door connector, harness, and grommet for damage/corrosion
Check related fuses and relays for the comfort/door circuits
Perform wiggle test on harness/connectors while operating locks and observe behavior
Use diagnostic tool to command the right front comfort solenoid (active test) and observe response
Measure supply voltage and ground at the solenoid connector while commanding the solenoid

Signal parameters

Activation supply voltage: should be battery voltage (~12 V) at the solenoid positive terminal when commanded
Ground switching: BCM commonly provides ground or switched supply; check for switching at command
Coil resistance: low-ohm coil (measure with ohmmeter); compare to manufacturer spec
Current draw when energized: expected low-amp draw (verify with clamp meter) — abnormal high or zero indicates problem
Command signal from BCM: pulsed or steady output as shown by diagnostic tool during active test

Diagnostic algorithm

Confirm DTC B1114 with a capable diagnostic tool. Note any companion or U-codes and the occurrence count.
Attempt an active test from the diagnostic tool to operate the right front comfort solenoid. Listen and observe the door/latch for movement.
With the solenoid not energized, disconnect the solenoid connector and inspect pins for corrosion, bent pins, or water ingress.
Measure coil resistance across the solenoid terminals (connector disconnected). If open or shorted relative to spec, replace the solenoid.
Reconnect and backprobe the supply and control wires. Command the solenoid while measuring voltage at the connector: verify ~battery voltage on supply and that the control line switches (voltage or ground) when commanded.
If control voltage is absent or incorrect, trace continuity from the solenoid connector back to the BCM/fuse/relay. Repair any open or short circuits, repair damaged harness grommets, and secure connectors.
Check related fuses and relays; replace as required. If supply and control are present but solenoid does not operate, bench-test the solenoid with a fused 12 V supply to confirm operation.
If harness and solenoid test good but control still absent, test BCM output using wiring diagrams and module activation procedures; consider BCM reflash or replacement only after verifying wiring and solenoid.
Repair or replace faulty components, clear codes, and re-test operation and road/functional test; confirm no reappearance of the code.
Document repairs and advise on corrosion protection (dielectric grease, grommet seals) to prevent recurrence.

Likely causes

Corroded/loose connector at the right front solenoid
Open or short in the harness between BCM and solenoid
Solenoid coil failure from wear or contamination
Blown fuse or weak relay in comfort supply circuit
Intermittent BCM driver or software glitch

Fault status

⚠️ Status

Right front comfort solenoid circuit fault — open/short/no activation or intermittent operation detected.

🟡 Repair difficulty: Medium
