MFA
Fix your MFA
If none of the functions of the MFA work, including the clock:
The first step is to disconnect the earth at the battery and then re-connect it. This serves to clear and reset the computer memories.
Then check the fuse and whether other electrical items on the circuit work. If they are all ok, then there is either an interruption in the power supply or the earth to the MFI unit, or a break in the printed circuit or the unit is faulty.
To check for a power supply connect a voltmeter to the battery live connection to the dash, not forgetting to connect the negative lead of the voltmeter to a good earth.
You can check this without removing the instrument panel cluster.
