Ford focus dash board light

first check your battery and cables... a dying battery and/ or corroded, loose cables may be the cause all those problems

If you don't have the owner's manual, you can get a PDF file of it from a USA ford website: Google search 2005 ford focus owners manual

The battery light means bad battery, alternator, or wires

Oil light means low oil level, bad oil sensor or bad wire to sensor

Abs light, check brakes or wiring to speed sensors or abs computer

Orange check engine light, a sensor or other electrical part has failed or wire broken to that sensor. You will need an obd2 scanner to find out trouble codes!

But, if ALL OF THE LIGHTS ARE ON while car is running, you really need to check and make sure the battery and charging system is OK FIRST

Any time you get a light on the dash,of any vehicle ,you need to check your owners manual.
Next ,you need a code reader or better yet,a scan tool hooked to the vehicles diagnostic connector, under the dash to check for codes. I am really suprised at the hundreds,if not thousands of people that don't know that.
The vehicle symptoms will be found, after your have a code(if any) and follow some type of testing proceedure.

new dash unit complete i think

Other systems that won't work like the radio or HVAC? Could be the battery saver relay.

it's an indicator warning you of emissions and/or engine control failure.
