Technical C1121 and C1045 fault codes help please

[Benscab123]

Getting these codes when plugged into a snap on solus. Abs light and brake warning light on dash. Any ideas anyone ?
Also - how the hell do you get the abs wiring connector off the module ? There’s some kind of retaining clip but I can’t for the life of me see how it comes off .
Thanks in advance for your help.

This lot covers C1121.

C1045 is not found on FF. But this suggests an ABS pump fault.

It could be a wiring fault or the pump is fubar. Do some google research and some more checks on your car.

Before you stress about what might be going on (ABS pump rebuilds are (very) not cheap) but used pumps are around £20.
