Help - XM Warning Lights

[Assich]

I've never seen these together before, the exclamation and the brake lights warning lamps on together for a few seconds then go out. Occasionally accompanied by the large STOP warning light. Seems to be randomly but generally occasionally under hard acceleration from low speed or turning a corner. LHM, oil and coolant levels all good. I have tried disconnecting the LHM and coolant level sensors one at a time with no change. Same with oil pressure. Suspension, steering and brakes appear fine pressure wise.

Front brake pad wear sensor?

Unfortunately like many xm's the wiring harness is no longer there so unlikely but I'll check. I' m thinking I can connect what's left on the body connector and see if I get the same warning lights. Thanks.
