Replace your failed engine computer with an OEM 2010 Ford Focus 2.0L PCM (also called an ECM or ECU), programmed to your vehicle before it ships.

This module is a direct replacement for units carrying service number AS4A-12A650-GC and hardware codes AS4A-12B684-CA / CB. Every unit is refurbished, bench-tested against OEM specification, and flashed with the latest manufacturer software updates.

Also replaces service numbers: AS4A-12A650-AVB, AS4A-12A650-ARA

What you receive

• Programmed to your VIN before dispatch, so it installs plug and play
• Bench-tested by our technicians before it leaves us
• Lifetime warranty for as long as you own the vehicle
• Free US shipping, typically delivered in 2-4 business days
• No core charge – keep your old unit

Common symptoms of a failed Ford Focus PCM

• Engine cranks but will not start
• Misfire codes that stay on one cylinder after replacing that coil
• Module codes P0601, P0603, P0605 or P0606
• Intermittent stalling or rough idle
• No communication with a scan tool

Important: replace the coils too

A shorted ignition coil is the usual cause of a damaged coil-driver circuit inside the module. If a failed coil took out your PCM, replace all coils and spark plugs at the same time, or the replacement can fail the same way.

Note on PATS anti-theft

Ford vehicles use PATS. Depending on model and year a key relearn may be needed after installation. We will tell you before shipping whether yours requires it.
