This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble talking to the part that helps start the engine when it's cold. It's like when your phone can't connect to Wi-Fi.
The Powertrain Control Module (PCM) is not receiving the expected signals from the Glow Plug Control Module 2, which is needed for proper engine starting and operation.
The P06FC code indicates a communication issue between the Glow Plug Control Module 2 and the Powertrain Control Module (PCM). This could be due to a faulty module, wiring issues, or a problem with the PCM itself.
• Difficulty starting the engine
• Check Engine Light is on
• Poor engine performance in cold conditions
• Faulty Glow Plug Control Module 2
• Damaged or corroded wiring/connectors
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, second generation
• Use an OBD-II scanner to confirm the code.
• Inspect wiring and connectors for damage or corrosion.
• Test the Glow Plug Control Module 2 for proper operation.
• Repair or replace damaged wiring/connectors.
• Replace the Glow Plug Control Module 2 if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regular inspection of electrical connections.
• Ensure proper maintenance of glow plug system.
• Keep vehicle software updated.
Communication Issue
• Have a professional diagnose the issue.
• Avoid driving in extremely cold conditions until fixed.
Check with your vehicle's manufacturer for warranty coverage on engine control components.
This code has been associated with diesel engines that rely on glow plugs for cold starts.
Moderate – It should be addressed soon to prevent starting issues, especially in cold weather.
Ignoring this issue could lead to starting problems, which may be inconvenient and potentially unsafe in cold weather.
• Engine cold start
• Normal operating conditions
The Glow Plug Control Module is typically located in the engine compartment, near the cylinder head.
Q: Can I drive with a P06FC code?
A: It's possible to drive, but you may experience starting issues, especially in cold weather.
Q: How do I clear a P06FC code?
A: Fix the underlying issue, then use an OBD-II scanner to clear the code.
