Bulletin No.: 03-05-25-008

TECHNICAL
Subject:
Intermittent/Constant ABS MIL Illuminated (Replace Both Front Wheel Speed Harnesses)
Models:
2001-03 Buick Century, Regal
2001-03 Chevrolet Impala, Monte Carlo
2001-02 Oldsmobile Intrigue
2001-04 Pontiac Grand Prix
Condition
Some customers may comment on an intermittent or constant ABS malfunction indicator light.
Cause
The front wheel speed sensor harness may wear or come into contact with the tie rod end stud. Additionally, the harness may, in some instances, loop over the tie rod stud. In this case, the wheel speed sensor should be examined for damage.
Correction
Replace original wheel speed sensor harnesses by splicing in revised wheel speed sensor harnesses. The new design harnesses are of a different length and have revised retention clip locations. Use the following procedure to replace the harnesses.
1. Raise and suitably support the vehicle on a hoist.
2. Disconnect the left wheel speed sensor harness from the sensor/bearing assembly.
3. Remove the harness retainers from the lower control arm.
4. Follow the harness back to the point where the harness enters the larger engine harness conduit.
5. Cut the electrical tape and open the conduit. Select a location where the splice will be within the engine harness conduit. Cut the original harness off.
6. Using GM/Packard Seal and Crimp Connectors, splice the two wires from the new harness to the old. Specific instructions for use of the Seal and Crimp Connectors are printed on the inside of the cardboard overleaf sealing the bag in which the harness is shipped. If Seal and Crimp Connectors are not available, you may use the crimp and solder type included with the harness kit.
7. Retape the conduit closed making sure to create an effective seal against road splash.
8. Route the replacement harness following the same path as the original. Fully seat the 4 retainers into the control arm.
Note: In the next step you will be required to measure the distance between the last retaining clip in the control arm and the end of the electrical plug that connects to the wheel speed sensor. Failure to properly perform this measurement and suitably adjust the harness may result in entanglement or infringement on the tie rod stud.
9. Hold the end of the new electrical harness and stretch it firmly. Due to manufacturing tolerances, you will need to measure from the end of the plug (that attaches to the wheel speed sensor) to the rear edge of the first retaining clip. This distance must not exceed 24.7 cm (9.75 in). If the distance is equal to or greater than 24.7 cm (9.75 in), you must move the retaining clip to allow more slack at the control arm and less between the wheel speed sensor and the retainer. Repeat the measurement until properly adjusted.
10. Disconnect the right wheel speed sensor harness from the sensor/bearing assembly.
11. Remove the harness retainers from the lower control arm.
12. Follow the harness back to the point where the harness enters the larger conduit.
13. Cut the electrical tape and open the conduit. Select a location where the splice will be within the larger harness conduit. Cut the original harness off.
14. Using GM/Packard Seal and Crimp Connectors, splice the two wires from the new harness to the old. Specific instructions for use of the Seal and Crimp Connectors are printed on the inside of the cardboard overleaf sealing the bag in which the harness is shipped. If Seal and Crimp Connectors are not available, you may use the crimp and solder type included with the harness kit.
15. Retape the conduit closed making sure to create an effective seal against road splash.
16. Route the replacement harness following the same path as the original. Fully seat the 4 retainers into the control arm.
Note: In the next step you will be required to measure the distance between the last retaining clip in the control arm and the end of the electrical plug that connects to the wheel speed sensor. Failure to properly perform this measurement and suitably adjust the harness may result in entanglement or infringement on the tie rod stud.

I'm looking to have some body work done on my wife's 1973 Buick Century. I've checked the J.C. Whitney web site, but they don't have panels for this particular model. Does anyone know of another source for these items? Thankx.

Are You in a cold winter climate?? . I have a 2000 century and in cold weather the mileage falls from 24-26 local driving to 18-21 Mpg. I have a scangauge installed and can monitor gas mileage on the fly plus lots of other things going on under the hood.
I see the exact some thing here.
I had the same exact problem, It was the alternator, tested bad. They replaced it
problem seemed to go away, the following week the new part failed and they replaced it again. seems to be fine now. Yes that brace needs to be removed to replace the battery. I soaked the bolts with wd-40 then it come off without a hitch. For the record my 2000 buick century has 58000 miles.
this morning drove the car no problem but 7 hours later wouldn't start
it finally did start with cable but whats wrong i dont have the book(its a 98 buick century)just bought the car 3 weeks ago to a garage...
Thanks,
Jeff
After replacing the screw and putting everything back together, now when the wipers are in timer mode, the wipers pause in the middle of the windshield. Other then that the wipers work ok.
So I have two questions:
1. How do i fix the pause location?
2. Which side does the longer wiper are go in? I wasn't sure if I mixed them up. I have the larger arm on the passenger side. Is this correct?
Thanks for any help you might be able to offer.
Cheers, David

When you start out cold the vehicle shifts up to drive then just kinda nothing happens. Like it is out of gear. shift to lower gear & it goes until it hits drive & then nothing. Shift down again it starts going & then put it in drive & it finally goes thru gears & keeps going. Now you can stop & start & no problems. Stop, floor it, it shifts thru all gears & is fine. Let it cool down for a few hours & the same problem. Transmission fluid is full & no sign or smell of burnt fluid. In my past experience when the filter was dirty, a vehicle wouldn't shift out of gear so I don't think it would be the filter. Any one have any ideas of what's going on?

Another word of warning with the 03 Century. GM lost a class action suit involving this car and a number of others. It had something to do with their custom coolant DEX Cool. It didn't get along with the gaskets very well. If I understand it right, the coolant ate the intake manifold gasket. Or something like that. I'd look at an '04 if I could find one. '03 was the last model year for that particular engine in the century.
