The best way to diagnose this latch is with a compatible scan tool. The vehicle's computer monitors the latch function and you can get it to release if it is stuck in one position with the scan tool if the motor is not damaged. You can also check the power from the latch if you have a volt meter and see if the striker switch was damaged:
1. First check for codes in the power trunk module with a scan tool if you have one.2. If there are no codes, backprobe the Violet and Orange wire, and the Violet and White wire with your volt meter.3. As you move the striker open and close, these two wires should toggle back and forth. One will lose voltage, then the other. If one or both of the wires never changes with the striker is open or closed, then check for a weak ground on the Black wire, before suspecting a failed striker switch.
