B1667 Code: Meaning, Symptoms, Causes & Fix

Overview

B1667 is triggered when monitoring logic identifies an issue with Mirror Driver Up/Down Motor Stalled affecting body electronics and comfort modules.

Symptoms

feature inoperative intermittently
module resets or glitches
related warning lamp illuminated

Common causes

Control module logic or calibration issue affecting mirror driver up/down motor stalled
Component failure in the monitored system
Connector pin damage/corrosion or harness stress near related components

How to diagnose B1667

Confirm B1667 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to mirror driver up/down motor stalled for obvious defects.
Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code B1667

Low: This code is low to moderate severity in most cases, but diagnosis is still recommended to avoid recurring warnings.

Can you drive with B1667?

The vehicle is often drivable with B1667, but plan a repair window to prevent repeat faults.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (generic) in the mirror driver up/down motor stalled circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify B1667 remains cleared under the conditions that originally set the code.

Fix options

Clear code and confirm through drive cycle.
Test component operation and replace if faulty.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$90-$400

Common mistakes when diagnosing B1667

Replacing parts without verifying voltage, ground, and signal integrity first.
Ignoring related stored/pending codes that indicate upstream faults.
Skipping post-repair verification drive cycle and readiness checks.

B1667 in common vehicles

B1667 appears across makes such as Mazda, Subaru, Lexus, Jeep. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes B1667?

B1667 is commonly set by generic faults affecting mirror driver up/down motor stalled.

How much does it cost to fix B1667?

For B1667, repair costs are typically $90-$400 depending on exact root cause, labor rates, and part quality.

Can I clear B1667 without repair?

You can clear B1667 temporarily, but the code usually returns until the underlying fault is corrected.
