Post by: clairedave on January 31, 2006, 21:57:27

But works ok from passenger side?have changed door actuators but no different.....this is doing my head in and i would be grateful for some help or advice please.Could it be the alarm?? :twisted:

The only thing that springs to mind is the Central Locking ECU gone if the actuator has been changed.  :?

Right, just looked it up in the Haynes Manual and in section 13.112 under the heading Central door locking system control unit (1990-on models) removal and refitting it says:

"173The central door locking system is now activated from both driver's and passenger's doors, and an activator is located in both front doors. The electronic control unit is located on the steering column support bracket.
174 Disconnect the battery negative lead.
175 Remove the lower facia panel.
176 Disconnect the wiring multi plug.
177 Unscrew the mounting screws and remove the control unit from the steering column support bracket.
178 Refitting is a reversal of the removal procedure."

According to the wiring diagram there should be 12 connection points on the ECU but only 9  are used.
From left to right, as it is on the diagram, the wire colours and terminal  numbers, marked with (), should be as follows:
Yellow/Orange (4)
Yellow/Orange (6)
White (3) - Connected to Fuse A5
Red/Pink (1)
Spare (5)
Red/Pink (2)
Orange (7)
Pink (8)
Brown/Pink (9) - Connected to Fuse C7
Spare (10)
Earth (11)
Spare (12)

Hope that help you get it sorted.  :wink:
