Causes

Damaged or pinched wiring harness on the mirror horizontal feedback signal
Corroded or loose connector terminals at the mirror or module
Water intrusion in the mirror assembly
Failed mirror motor/feedback potentiometer or mirror control module
Aftermarket mirror or recent repair with incorrect wiring
Short to ground inside a splice, harness connector, or BCM

Symptoms

Side mirror will not move or will not center/hold position correctly
Mirror position memory does not function or reads incorrectly
DTC B2323 stored and possibly repeated after clearing
Intermittent mirror operation or loss of horizontal control
Possible diagnostic trouble light or message related to mirror/memory

What to check

Perform a visual inspection of mirror, door boot, and wiring for damage or corrosion
Check connector mates for bent pins, corrosion, or moisture
Backprobe the mirror horizontal feedback signal with ignition ON and operate mirror
Measure voltage between feedback signal and ground; check continuity to chassis ground if low voltage
Inspect for damaged wiring where the harness flexes at the door hinge/boot
Scan for additional related codes (mirror/memory/BCM) and note freeze frame/occurrence

Signal parameters

Reference voltage (if applicable): typically 5 V reference from BCM or mirror module
Expected feedback signal: variable 0–5 V proportional to horizontal mirror position (not stuck near 0 V)
Short-to-ground symptom: feedback signal near 0 V regardless of position
Open-circuit symptom: feedback signal absent or floating (may show erratic voltage)
Typical ground continuity: low resistance from mirror ground to chassis (

Diagnostic algorithm

Retrieve freeze frame data and any related codes; record mirror behavior when code set.
Perform visual inspection of affected mirror, wiring, and door boot for damage, corrosion, or water entry.
With ignition ON (accessory), backprobe the feedback signal pin at the mirror connector. Command mirror horizontally while observing the signal voltage. Expected: varying 0–5 V. If signal is ~0 V, proceed.
Disconnect mirror connector and measure resistance between the signal wire and chassis ground. A near‑zero reading indicates a short to ground in the harness or connector.
Inspect and wiggle the harness from the mirror to the door hinge while watching the signal/continuity to reproduce intermittent shorts. Pay attention to the harness through the door boot.
If harness/connector appears intact and no short is found, disconnect the mirror assembly and bench test the mirror potentiometer and motor per manufacturer procedures. Replace mirror assembly if internal short or failed potentiometer is confirmed.
If the short is upstream, trace and repair the damaged section of wiring, repair or replace corroded connectors, and reseal grommets/boots to prevent reoccurrence.
After repair, clear codes and verify proper operation and that the feedback voltage varies correctly across full mirror travel. Re-scan to ensure the code does not return.
Note: Use appropriate vehicle-specific wiring diagrams and safety procedures. Disconnect battery if required by vehicle service information before connector pin repairs.

Likely causes

Broken insulation exposing signal wire to chassis ground
Terminal pushed out or bent in mirror connector shorting to ground
Failed potentiometer inside the mirror assembly
Corrosion/contaminant creating a ground path at the connector
Short in the wiring harness where it passes through door hinge/boot

Fault status

⚠️ Status

Mirror driver horizontal feedback potentiometer circuit short to ground — feedback signal is near ground indicating a short on the horizontal position sensor circuit.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.5 hours
