2010 Fortuner rear diff lock actuator giving error codes

Post by Johnny28 »

Dear Gents
My 2010 Fortuner rear diff lock seem to be malfunctioning. In 4lo the Diff lock works engaging and disengaging the rear diff lock. Back on tar road and after a short drive the dash lights up, Vsc, abs brake warning stay on. Unplug the diff lock and after short drive, light go off. Plug it in and after a short drive all light come on and stays on. Stealers say to replace actuator. Unit cost R12k. Is der not other way to repair this unit. I'm in Durban.

Hi John. The electric actuators are prone to becoming "sticky", mostly due to water ingress which turns the grease inside into goo. I would suggest that as a first step to remove, strip, clean, re-lube and re-fit the actuator. Hopefully that will solve the problem. :winkx:

Hi Mud dog.
Thanks for advice. I strip it, it looked brand new inside. Cleaned and regreased. No luck, still getting error codes after about 20kms on tar road. Not sure if electrical component is damaged.
