Jeep GC WG 2.7 CRD. Where does ABS sensor cable connect?

Hi All,

further to my earlier queries re my ABS system. I have had a diagnosis that revealed a faulty Left Front Wheel speed sensor so have ordered a new replacement that I propose to fit myself.

My problem is that every manual I refer to (and I have a fair few), talks about the "G Switches", to which the sensor(s) connect, being under the carpet under the rear seat. Well, in short, they are not! It may be true for the petrol (gas) engined WJs but not for the diesel engined WG version. All the space under the rear seat is taken up by the Radio/CD amplifier, the handles for the jack and the apology for a wheelnut (lug nut) wrench that live there.

The wheel speed sensor comes with a fair length of cable moulded onto it, and a connector at the other end. What I don't want to do is go grovelling underneath in a dirty environment, when I should perhaps be grovelling inside on top in a relatively clean environment.

If anyone can offer a drawing of the wheel sensor cable runs I would be most grateful.

T.I.A.

Tony N

Re: Jeep GC WG 2.7 CRD. Where does ABS sensor cable connect?

Hi Tony. I don´t know when it changed, but older WJ´s have a separate G-switch under the carpet of the rear seat, newer WJ´s have the G-switch internally to the ABS controller (CAB)
The Wheel speed sensors in all cases connect to the CAB, not to the G-switch. The G-switch in fact also connects to the CAB and gives deceleration information to the CAB.
The wheel speed sensors have a connector close to the wheel, so you have to get dirty. See attached page.

Hi Frank,

thanks for your response.

Having been underneath (and got a bit dirty) I know that the connector shown on the page you sent does not exist on the WG diesel. The sensor/cable comes as an assembly, see: -

"http://www.ebay.co.uk/itm/Wheel-Speed-ABS-Sensor-Front-Left-Jeep-Grand-Cherokee-/181267448647?pt=UK_CarsParts_Vehicles_CarParts_SM& fits=Model%3AGrand+Cherokee&hash=item2a3461c347".

I do know that the WG series like mine were made in Austria, and my guess is that the sensor/cable assembly is cheaper to produce than with an intermediate connector, and probably cheaper to assemble in production. Never mind the poor guy who has to replace it - he can sort out his own salvation!

All I need to do now is suss out how the connection is made to the CAB. I guess I will have a better idea on that when I receive the replacement part.

Cheers

Tony N

Re: Jeep GC WG 2.7 CRD. Where does ABS sensor cable connect?

Hi Tony.
My WJ is a WG as well (made in Austria), eventhough its a 4.7L. I can´t believe that they would make it different on a CRD. There could eventually be a difference for being a right hand driven jeep.
Just had a look underneath, and on mine the connector sits just where the lower control arm connects to the body, see attached picture from the left front wheel side. Item 1 is the aft lower control arm mounting bolt, item 2 the upper control arm and item 3 the wheel speed sensor connector.
The CAB has just one big connector and not separate inputs.

Thanks Frank,

I'll trace it back when I get the new part, and hopefully it will be an easy connection.

I've already had the sensor detached from the hub carrier, so I know I'm not going to shear the little set bolt that holds it. One potential worry out of the way.

Cheers

Tony N

Many times the connector is the problem. Any water ingress will cause a change in resistance and can set the ABS fault light. It would be worth to search for the connector and check for moisture/corrosion.
