Posted: Tue Nov 07, 2017 19:30 Post subject: 4WD Light Flashing |
|
|
I have a 2001 LWB 3.0L Citation with manual gearbox.
It engages 4WD and disengages, but the green light keeps flashing. I've reversed it so many times, but the light is still blinking.
I've had all the connections and vacuum pipes checked and all are in good shape.
There's something odd though, because when I turn on the ignitionon, the light stays on for about 10 secs and then goes into the blinking mode (normal I think), but at the same time, the battery light and the handbrake light start blinking as well.
Just in case, I've had the cluster out and checked the circuit board, and all's nice.
As ever, I'd be grateful for any guidance on how to find the culprit.
Thanks

Mine does the same, The system works fine just that the light flashes all the time. As it works I havent bothered looking at it. I was told it's probably a wire come of the solinoid. _________________ Never let a meal go by----Empty sacks dont stand up!!! |

I've nowread Rhangars Sticky, and for anyone wanting to find out how the Trooper 4x4 system works, it's a Godsend.
I'm going to have my mechanic to check those suspects. |

You say it 'works' - so the flashing light doesn't matter too much - OK but to get 'normal operation' you need to fix the 4WD light to go 'ON' while in 4WD.
The movement of the half-shaft should trip a position-switch on the shaft and send a signal back to the 4WD Control Unit, which should make the light shine continuously. If the 4WD is working mechanically but the light still flashes, then this position-switch might be faulty - so you could remove it and check its function with a multimeter [or at least a battery and a bulb!] - it should close the circuit when the end is pushed-in.
Otherwise the line back to the 4WD Control Unit might be faulty. Check that by running a new line from the Switch Unit back to the 4WD Control Unit where the [probably] faulty line connects [I think it's #9]. If this new line makes the 4WD-light go 'solid', then you've proved that the cable back from the half-shaft was faulty - so your new problem is to run a permanent replacement cable back to the 4WD Control Unit - usually best to do it along the original cable-route.
Good Luck! _________________ 2002 LWB Trooper 3.0L
I've done some major repairs, including replacing half-shaft, replacing fuel-injectors etc. |

Thanks for the tips.
All sorted: 2 broken wires to the switches/valves on the front axle. |
