If you need help resolving this code, tell me your specific , whether both mirrors are failing, or if you recently made any FORScan modifications . I can pinpoint the exact wiring layout or fuse number for your vehicle!

You should see roughly 12 Volts (battery/alternator voltage).

: Signals a sub-type condition, specifically an open circuit (a broken link where electrical current cannot flow). Common Root Causes

If wiring and the sensor are intact, visit a Ford dealership. They can check for TSB (Technical Service Bulletin) 22-2147 or similar, which provides a software patch for the RCM that desensitizes it to normal signal fluctuations. ford b166a60

: The thin resistive wires on the back of the glass degrade and snap over time due to constant thermal cycles.

of the module or the vehicle's electrical system to see if the code clears, though hardware faults will cause it to return immediately.

: A sub-type byte that specifies the nature of the fault, in this case, an open circuit or an interrupt in the wiring. MFC Auction Common Causes If you need help resolving this code, tell

List the for the mirror glass replacement. Explain how to use FORScan to clear this code.

If you meant a different code, here are some close possibilities:

: Sometimes the sync is lost. Manually fold the mirrors toward the window, then use the interior fold button to cycle them out and back in. This can "re-home" the motors. : Signals a sub-type condition, specifically an open

When a door module flags a circuit as open, the source of the breakdown typically points to one of four vulnerabilities:

This unique hexadecimal identifier points directly to the passenger or driver side-view mirror heating circuit sub-system.

Are you seeing this code on a like an F-150 or an Expedition, and do both mirrors fail to heat or just one? Shop Ford Parts Online - Genuine OEM Parts
