Surely someone has had this issue and found a solution?

I have not had the problem but checked the Prado's Sevice and Repair Manual. Needless to say, it's pretty involved. Have any fault (DTC) codes been reported by the Body Control Unit? Without the fault code, you will struggle to find where to start looking.

I have ran techstream

no fault codes

So far narrowed down to

Next steps to do


1-CHECK HARNESS AND CONNECTOR (FRONT DOOR OUTSIDE HANDLE - -CERTIFICATION ECU) check resistance

If no good

REPAIR OR REPLACE HARNESS OR CONNECTOR

If good

2- CHECK FRONT DOOR OUTSIDE HANDLE ASSEMBLY (FOR DRIVER SIDE) requires some special tester

If good

REPLACE CERTIFICATION ECU

If no good

REPLACE FRONT DOOR OUTSIDE HANDLE ASSEMBLY (FOR DRIVER SIDE)

Can you swap the handle from another door to it for testing? also try a full battery off for 10-30 mins reboot of the car.. Sometimes the canbus can get upset.
