  • One touch 2-4 4x4 light not coming on

    Clicked the one touch 2-4 switch yesterday and noticed that the dash display didn't come on. I tried it when I first got the Surf a few weeks ago and it came on fine. Not entirely sure whether 4x4 is engaging or not. I slowed down and tried reverse as suggested in the manual, but still no joy.

    Anyone else had the problem?

    Hmmmm Join the club

    Tried Mine The First Week I Got The Vehicle And The 4x4 Was Working Fine !!!! Then Tried It After 3 Months And It Doesnt Work !
    I Have Replaced All The Vacuum Hoses,the Front Diff Solenoid,the Main Add Control Valves,the 4wd Switch And Still No Go !
    If I Can Figure It Out I Will Let You Know.next For Me Is To Unplug The 4wd Ecu And Have A Play With That ! But For You The First Thing To Check Is Hopefully The Vacuum Hoses From The Add Unit Down To The Diff

          So what does the add unit look like so I can check it? :p

          I've tried engaging H4L mode. The dash displays fine. 2-4 still won't after this.

            Worked it out. I'd forgotten to reconnect the connector at the base of the 4x4 shifter when I'd taken the console apart to do the stereo...
