Diff lock not engaging

Postby graham1 » 12 Aug 2017 07:50

Hi guys,

I only remembered now that I had difflock issues during our last Botswana trip.
When I flicked the difflock switch the difflock light and abs lights would flash. From what I remember, the difflock light needs to burn solid hey? And what should the abs light do?

I'll start with the vacuum lines, but the abs light flashing has me confused.

Yip, I'm busy trawling through all of them now :thumbup:
I can't seem to find anything about the abs light yet though, maybe I need more coffee. :)

ABS is disabled the moment the diff-lock switch is turned on, and the ABS light will start flashing.

Thus, the ABS light is doing what it should.

Aha, I thought that might be the case, but wasnt sure. Thanks Peter!
At least I can now just focus on the difflock itself then.

Also if the diff lock is engaged , you should hear a warning chime if you go over 25km/h

Hi Graham
a easy way to test the difflock and to see if its working....jack the rear of your Patrol and with the car in neutral start the engine
change the two vacuum pipes , (the pipe on the rear should have constant vacuum) around on the selonoid for the diff lock and with the handbrake off turn any one of the rear wheels slowly and it should engage the diff lock and both wheels should turn together
if it doesn't engage then your problem might be in the diff
