Cruise Control not working KV6
The cruise control on my petrol KV6 appears to have failed. Though I am an infrequent user, I do remember using it; I only bought the car last November.
Symptons are: 1 - main switch operated, green light comes on. (I'm assuming switch and fuse are ok). 2 - steering wheel switch (SET) operated - dashboard icon comes on, but speed (say 50mph) is NOT maintained. (I'm assuming switch works as icon now lit). 3 - as 2, but switch used for (+) mode, no increase in speed. (Same assumption as 2). 4 - leaving SET selected, with icon lit, but using accelerator to drive; if brake pedal is now used, icon goes off. (thus I am assuming brake pedal switch is ok). Note - I have added an led repeater for the brake lights, I can confirm brake lights and icon go off together. 5 - Vacuum pipe to throttle body; I have checked for cracks and disconnection, but NFF, though I have yet to go under car to check vacuum pump closely. Any suggestions? Stewart |

I had the same, turned out the pump didn't work, replaced and all was well.

Stewart; have you tried temporarily disconnecting your modification to see if it makes any difference?

It could be as simple as the vacuum pipe off the diaphragm housing (activating the throttle) having come off, or the adjusting rod having lost "grip". Both are simple fixes.

As in (2) above, icon does come on. I have also tried the reset switch on the wheel.

Yes the v6 has a pump, its located in the engine bay side of the o/s wheel arch.
The vacuum pipe goes from the pump to the bellows unit mounted on the side of the throttle body. Landrovers also use the same pump so not too hard to find a replacement. |
