B1676 on Lincoln by model: symptoms, diagnosis and fix
Roughly 46% of polled 2024 Nautilus owners (both ICE and hybrid) report a dead or dying 12V battery, sometimes with as little as 200 miles on the odometer. Two software-related causes identified: (1) Vehicle Dynamics Module stays awake and holds the CAN bus active after key-off (CSP 24P14), and (2) Driver Status Monitor Camera Module software keeps running after vehicle is off (CSP 24P08).
Common Symptoms
- no-start after sitting overnight
- clicking when pressing start button
- dim dome lights
- battery low message
- needs frequent jump start
How to Fix
Have dealer apply software updates CSP 24P14 (VDM reprogram) and CSP 24P08 (Driver Status Monitor Camera Module reprogram), test 12V AGM battery state-of-health, and measure parasitic draw. If draw still exceeds spec, have the dealer continue diagnosis and replace a failed battery under the bumper-to-bumper warranty. An OTA update consolidating these fixes is anticipated.

Frequently asked questions
What does B1676 mean on a Lincoln?
B1676 stands for "Battery Pack Voltage Out Of Range." A control module reports that its supply voltage has left the acceptable operating window. Ford's published criterion is battery voltage below roughly 9.7 volts for more than about 210 ms with vehicle speed above 20 km/h (12 mph), or above roughly 18 volts at any time. It is a supply-quality code that many Ford-family modules can set, and it commonly appears as a companion code when a weak or degraded 12V battery causes voltage sag during cranking or during auto start-stop restarts. Because the code is set by whichever module saw the sag, it must be read together with that module's identity — when it is stored by the ABS module on Ford-family vehicles it is frequently caused by an internal module fault rather than the battery itself. On Lincoln it is documented across 1 model: Nautilus.
What are the most common causes of B1676?
The most common causes of B1676 are: Weak, sulfated or end-of-life 12V battery (voltage sag under load or during auto-restart), Failing alternator / charging system, or overcharging producing high-voltage spikes, Corroded, loose or high-resistance battery terminals and ground straps, Blown module fuse, open or shorted module power/ground harness, Poor connector contact at the module; internal ABS module failure on some applications. The specific cause varies by vehicle.
How much does it cost to fix B1676 on a Lincoln?
Repair costs vary widely with the root cause and Lincoln model; each issue on this page carries its own estimate where one is published.
