There is a fault in the security system that is affecting the power door locks.
I am giving you a wring diagram for the power door locks. Look for the correlation or connection siganl from the secuirty sytem.
I am also giving you the security sytem, referred to as VSS, diagram and a diagram from the included test for door lock and system faults which is the pinout for the VSS connector.
Check the grounds in the diagrams as well. They should have a good, corrosion free, metal to metal connection.
