Why dont you follow the procedure below, it will show you how to enter 'test' mode on your car, and to get the DTC code (error code) and scroll further down to read it's description.

Here is a bit of info for the test mode of the focus dash .. long but informative

To access the test mode, hold the trip meter reset button in and turn the key to the on position, then the guages will do a full sweep and state guage on the LCD.. you are then able to prett the button to get the details

First digit structure is as follows:

Pxxxx for powertrain
Bxxxx for body
Cxxxx for chassis
Uxxxx for future systems

Second digit structure is:

P0xxx Government required codes
P1xxx Manufacturer codes for additional emission system function; not required but reported to the government


Third digit structure is:

Px1xx measurement of air and fuel
Px2xx measurement of air and fuel
Px3xx ignition system
Px4xx additional emission control
Px5xx speed and idle regulation
Px6xx computer and output signals
Px7xx transmission
Px8xx transmission
Px9xx control modules, input and output signals


The fourth and fifth digits designate the individual components and systems.


Here's a generic list of DTC codes for reference, makes the post a bit long but should do. These are for SAE standard ones, as used for SAE J2012 OBD-II:

Anatomy of the Diagnostic Trouble Code

A DTC is made up of 5 digits. The figure below demonstrates the
composition of a DTC. With this information it is easier to trouble shoot a DTC
without knowing the description of the code.
X X X X X

B-Body
C-Chassis
P-Powertrain
U-Network

0-SAE
1-MFG

1-Fuel and Air Metering
2-Fuel and Air Metering (Injector circuit)
3-Ignition Systems or Misfire
4-Auxiliary Emission Controls
5-Vehicle Speed Control and Idle Control System
6-Computer Output Circuit
7-Transmission System
8-Transmission

Fault 00-99

Types of DTC's
There are two categories of DTC's that apply to OBD II. They are listed
below with Type A being the more severe.
Type A
1. Emissions related.
2. Requests illumination of the MIL after one failed driving cycle.
3. Stores a freeze frame DTC after one failed driving cycle.
Type B
1. Emissions related.
2. Sets a Pending Trouble Code after one failed driving cycle.
3. Clears a Pending Trouble Code after one successful driving cycle.
4. Turns on the MIL after two consecutive failed driving cycles.
5. Stores a freeze frame after two consecutive failed driving cycles.
