02 rendezvous wiring harness
HI, my rendezvous all wheel drive an anti lock light kept coming on so I took it to a shop to have it looked at an had the computer put on it.it came up that the driver side bearing in front was bad.so I replaced it then it came on again so I had the computer put on it again,same thing came up.so I got another one because some times you get a bad one.but not twice in a row because it happened again.so I did some checking an found out that the harness is known to go bad too.so I bought a new one,now my question is this.I know it plugs in the back of the hub but the other end of the new harness the wires are bare.where does that end go.where does the harness lead up too, that the bare ends go,do I need to hook some kind of plug on the bare wires ends? thanks for your time. geneo70

RE: 02 rendezvous wiring harness
I haven't done that particular vehicle but the harness in question is called an extension harness and heads back to the EBCM. If it has small terminals on the other end you will need to do some delicate work to get them into the existing plug further up the harness. If those are truly bare ends you will need to so some soldering and shrink wrap to keep out the elements, which play hell with the wires over time. Starting off with the first plug (about a foot from the bearing) you follow the harness up the frame and see how far it reaches. That's where you will make your connection. Be sure to follow the exact same routing.

RE: 02 rendezvous wiring harness
Most of the after market replacement harness kits that I have seen are only a partial replacement. The reason that the ends of the wires are bare are because you are supposed to splice the wires together in the old harness at a location where they aren't likely to be damaged. However, I can give you a little more information that may save you time & money.

First of all, learning what codes mean can save a lot of time and money. Like the fact that there is no code that says that the drivers side wheel bearing is bad. There are several codes for the drivers side "Wheel Speed Sensor." If you check the exact code it probably was for a low input signal. Now you need to check "why" the signal is low. If there is no play in the wheel bearing you unplug the sensor & check for voltage at the plug while spinning the wheel. If it is producing the proper voltage you now need to check the connector and wiring to find why that voltage isn't reaching the EBCM (Electronic Brake Control Module.) 99% of the time I find the problem right there at the wheel. Either the connector is corroded or the wire is broken right at the back of the connector, actually inside the connector where you can't see it. I usually find this while checking continuity between the wheel sensor plug and the EBCM plug. If the wire is broken I usually install "heat shrink tubes" and solder the connection somewhere along the harness where flexing doesn't occur. If it is corroded I clean the connection and apply dielectric grease.

Any time you have the computer scanned record the code NUMBERS, post them here along with a description of the problem you are having, & we may be able to save you time and money by pointing you in the right direction.

Hope that helps. Please let us know what you find.

RE: 02 rendezvous wiring harness
I forgot to ask what is the sensor that is built in the new hub an bear

when they hooked the computer up on the car they took it for a drive an they came back an showed me this monitor an they compared the drivers side to the other side in the front an the lines on the computer were side by side an showed that the drivers side had e-regular readings an the other side was fine.what they showed me looked like a chart comparing one side to the other.does that help.I forgot to ask what is the sensor that is built in the hub an bearing for.

sorry for some reason I posted twice.

RE: 02 rendezvous wiring harness
just wanted to say thanks for your fast response to my problem an to day I got under there an replace the harness an did the wires like you said an worked great.thanks again for your help an Im sure I'll be asking more questions because from what I hear I'll be repairing more then driving on this car.geneo70

RE: 02 rendezvous wiring harness
The sensor built into the wheel hub is the Wheel Speed Sensor (WSS). I mentioned it in my first post. It is simply a small A/C generator. The faster the wheel turns the more voltage it produces. The vehicles computer compares the speed of each wheel to the Vehicle Speed Sensor (VSS.) If the VSS says that the vehicle is going 30mph, 3 of the WSS's say that those tires are turning 30mph, and one WSS says that that tire is turning 3mph, the computer realizes that the 3mph wheel is locked up and it pulses the brakes on that wheel to release it. (Anti-Lock Brakes)

What the mechanic showed you was likely just the voltage output on the front wheels in a chart format. It really only tells you that the voltage readings are irregular. A worn wheel bearing "Can" cause that, but you should check the bearing for play first. If the bearing doesn't have any play you need to check out the rest of the system before condemning the hub which is much more expensive than fixing a wire. That's why I prefer that you get the code numbers and post them here before buying parts. We can "Sometimes" save you buying parts that you don't need by telling you how to test things first.

At least I'm glad to hear that you got it fixed. So few people take the time to let us know how things turned out. We really appreciate you letting us know! Stop by any time for advice. Someone here can usually help out.
