ABS \ TC light on after front diff change

Just replaced out my front Diff after it went bang. Exchange all went well but now I have the abs and tc lights on. No faults showing on obd reader. No cables disturbed during work. Any ideas welcome.

When does light come on, as soon as ign on or when you start moving?

From your other posts I see you have a 2.4 Puma. I have wiring diagrams for the 2.2 which has differences to the 2.4, (don't have diags for 2.4). The 2.2 has an earth point for the instrument panel, located as in the attachment. Might be the same location on yours, and might have been disturbed when the transfer box was worked on. Long shot but worth a look? Also there are several earths which are fastened to the drivers side of the transfer box, were these all refitted?

Oops - missed the attachment off

The lights come on with the ignition and stay on.

Have you driven it? Had this issue with my Focus last week after a front drive shaft replacement. When I drove it a short distance light went out.
