2014 Hilux SR Dual Cab Rear POWER DOOR LOCK CONTROL SYSTEM

[tdos105]

Hello

for some time now i have had intermittent issues where the Power door lock control system would play up.

At first Passenger door wasnt locking or unlocking. 

Then it started to work and moved to Drivers door

Then that started to work and then the back passenger and then rear drivers. 

Now i only have fronts unlocking and locking via the wireless key and also by inside the drivers panel.

When i put key inside the cylinder of drivers door only front locks and unlocks

I have checked everything from the ECU and all fuses and taken all panels off the doors to check.

The actuators on all doors are fine as when i put 12v to them manually they operate.

Now it seems the rear isnt getting any power to them as I can feel any movement to the lock itself.

Looking at a repair manual it says the Integration unit could be at fault I have checked it under the Drivers side however its a complete sealed unit.

 

Does anyone have any fixes for this or know if there is a sync/reset option for door locks.

 

I have also tried disconnecting battery for 20 min or more to reset ECU
