I think you could use this manual method instead.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from. www.reliable-store.com
wiring diagram/ electrical, error/fault codes
repair instructions including removal, installation, assembly
parts info, pcv, service
etc. a lot more
Check the wiring inside the rubber boot from the body to the door . Opening an closing the door a million times can cause these wires to break . Testing the electrical circuit using a DVOM - digital volt ohm meter before replacing parts is the proper way to diagnose automotive electrical circuit's . You can find free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click body & accessories ,then under subsystem click on power locks or windows ,which ever you want to diagnose first .

When the ABS light is on, the brakes should revert to standard braking.
The only time ABS should invoke is when the tires are slipping as sensed by the wheel speed sensors when the wheel locks up on any of the axles.

There are two basic types of anti-lock systems available for this vehicle; a Rear Wheel Anti-Lock (RWAL) brake system and 4 Wheel Anti-Lock (4WAL) brake system. The 4WAL system has two variations; a 3 sensor system and a 4 sensor system. The 2WD vehicles will be equipped with the 3 sensor system, but the AWD vehicles can be equipped with either. The systems are easily identified by looking at the rear wheels for a sensor harness. If there is a sensor harness and thus, rear wheel sensors, it is the 4 sensor system. If the vehicle is not equipped with a harness, it is the 3 sensor system. The 4 sensor system takes it speed references from each of the wheels. The 3 sensor system takes its speed references from each of the front wheels and the vehicle speed sensor located in the transmission (2WD) or the transfer case (AWD).
The RWAL system components consist of the Vehicle Speed Sensor (VSS), the Electronic Control Unit (ECU), the isolation/dump valve and the Vehicle Speed Sensor Buffer (also known as the Digital Ratio Adapter). The ECU also receives signals from various brake switches.
The 4WAL system components consist of the Electro-Hydraulic Control Unit (ECHU) valve (also known as the Brake Pressure Modulator Valve or BPMV), the wheel speed sensors, Vehicle Speed Sensor (VSS) on 3 sensor systems and the VSS Buffer.
First, also check fuse B6 in that same kick panel fuse/relay carrier.
The other microswitches that affect the operation of the top (for a MY99) are:
B-pillar microswitch, located just below the B-pillar over the driver's
left shoulder, behing a long, semi-circular carpet-covered plastic
Clamshell microswitch located on top of the electric motor just forward of the third brake light;
Roof Latch microswitch (there are actually two switches located there),
located inside the receptacle in the middle of the top windshield frame.
First, I would verify that both windows simultaneously drop about 4"
when you first pull the latch down (with the parking brake pulled up and
the idiot light on).
If that doesn't happen, you may have a problem with one of those two
microswitches. Poke your finger into where the latch goes into the
receptacle while you keep the top switch depressed, and see if you get a
I would also take out the double relay (in that same relay carrier in
the driver's kick panel) and tap it on a flat, hard surface a couple of
times, then install it and pull it off a couple of times (removes light
corrosion on the terminals) and see if that solves your problem. The
double relay is the only double relay in the relay carrier, and it is
located in the third row from the bottom (bottom row has no relays),
second from the right.
it would be cheaper to call out local brakedown recovery people , they will have one and remove it for you, you possibly could buy one from a motor vehicle supply store expencive way or online, sorry its not that helpfull
Truely I am not trying to blow-off you and your question but, based upon the sheer number of pages (at least 20-pages or more) that would have to written under this forum, I strongly suggest you go to alldatadiy.com for the most complete lighting component locations and wiring diagrams. It covers the fuses, wiring identification diagrams, relays, ground locations, and splice locations. It is about $25 for a 12-month subscription. They have the most extensive wiring and location diagrams I have seen anywhere. That is where I go with my questions for this subject. That site is also filled with everything you wanted to know about your entire vehicle - bumper to bumper.
Let me know if this helped, or if you have additional questions or information. Feel free to contact me at FixYa.com.
>>>>FIRST disable the air bag system You'll need to remove the upper and lower steering column covers. Also all the trim under the drivers side, kneee bolster, etc... The ignition switch has 2 screws holding it on. Remove those screws and all related wiring harness. Then the switch. Here is the procedure from GM......
Place the multifunction lever in the center or the OFF position. Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.
Disconnect the battery negative cable. Disable the SIR system. Remove the steering wheel inflator module. Remove the horn plunger contact. Remove the steering wheel. Remove the tilt wheel lever. Remove the ignition lock cylinder. Remove the upper steering column trim cover.
Couldnt find a diagram. Hope this helps.
The Central Electronics module is detecting a fault in on of the door locks. Its not necessary that the lock is faulty, it may just need to be adjusted. To be more specific, the locking knob that goes up when vehicle is unlocked and goes down when locked , is connected via a linkage to a microswitch on the door lock actuator. The microswitch has three positions. top position is unlocked, center is neutral, bottom is locked. However after any cycle of the lock/unlock switch, the microswitch has to return to the neutral position for it function correctly. Most likely your vehicles drivers door lock microswitch does not return to the center/neutral position after you lock you car which causes the alarm to go off. In this case you should have the drivers door lock assembly replaced by a good knowledgeable workshop, and the dealer isnt one of them.
The P1751,front right speed sensor has to do with the anti lock brake system.You have to look at it,and determine if the sensor itself is built INTO the wheel bearing,or if the sensor just bolts to a bracket.If it bolts to a bracket,pretty easy to remove and replace.If the sensor is built into,or part of the wheel bearing assembly,much more difficult and time consuming repair as the entire wheel bearing would require replacing.........The P1723, Automatic Transmission control relay open/short is going to require a digital volt ohm meter,and electrical expertise.The wires to and from the relay are going to have to be backprobed and checked for continuity which is also going to require electrical diagrams showing where the wires begin and end,and what terminals are involved in the circuit.This type of information is only available through pay sources such as All Data,Mitchell Manuals,etc.You could also buy a Chilton manual specifically for your vehicle model,but leaf through it first before buying and see if the electrical diagrams you need are in it.Good luck.
