What Does B2116 Mean?
This code indicates the Body Control Module (BCM) has detected that the driver's door reset switch is stuck in an active or closed position. The reset switch is typically part of the door latch mechanism or a separate switch used to reset door lock/unlock functions or window auto-up/down features. The BCM continuously monitors this switch and has determined it is not returning to its normal rest position, which can affect power window operation, door lock cycling, and memory seat functions.
Common Causes
45%
Mechanically stuck or jammed door reset switch due to dirt, debris, or internal component failure
30%
Shorted wiring or connector corrosion in the driver door harness causing continuous ground signal
15%
Failed door latch assembly with integrated reset switch microswitch stuck closed
10%
BCM internal fault or software glitch misinterpreting switch input signals
Diagnostic Steps
1
Step 1: Perform visual inspection of driver door reset switch location and door latch assembly for physical damage, debris, or obvious mechanical binding. Manually operate the switch or latch if accessible to check for free movement.
2
Step 2: Using a multimeter, backprobe the reset switch connector at the driver door to measure voltage/continuity. Check for constant ground or closed circuit condition (expected is open circuit at rest). Compare readings to vehicle-specific wiring diagram specifications.
3
Step 3: Disconnect the driver door reset switch connector and monitor live data on scan tool to see if BCM registers switch as released. If code clears, switch is faulty; if code persists, check for short to ground in wiring harness between switch and BCM.
4
Step 4: Inspect driver door wiring harness through door jamb flex point for pinched, chafed, or corroded wires. Pay special attention to areas where harness bends during door operation. Perform continuity and isolation tests on suspect circuits.
5
Step 5: If wiring and switch test normal, suspect door latch assembly internal switch failure. Remove door panel and latch assembly, bench test the reset switch function with multimeter while manually cycling the latch mechanism.
6
Step 6: After repair or replacement, clear codes, cycle door locks and windows through full range of operation multiple times, and verify code does not return. Test all memory and convenience features tied to door switch inputs.

The most common cause of B2116 (Door Driver Reset Switch Stuck Failure) is: Mechanically stuck or jammed door reset switch due to dirt, debris, or internal component failure
Typical repair costs for B2116 range from $120 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
This code does not affect vehicle safety or drivability and it is safe to continue driving. The primary concerns are convenience feature malfunctions such as power windows not auto-closing, door locks cycling unexpectedly, or memory seat functions not working properly.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to B2116 to identify the root cause.
