T's either under the dash board on the drivers side behind the fuse box or behind the kick panel on the drivers side by the parking brake pedal. They put them in one of those 2 places between 98 and 01.

I have a 2006 mazda 5 it has the code uo101do you know where the brake on the wire could be

Are you having any problems with the vehicle or warning lights coming on or is this just a code that was pulled up with an OBD2 scan tool. The U code is simply indicating that the engine computer lost communication with the transmission computer for some unknown reason. These codes are set all of the time for varying reasons between the engine, transmission, body, antilock brakes or other modules. Since all of the computers or modules communicate with each other on the same two set of twisted CAN or Computer Area Network Wires it is not uncommon for one module to not get an immediate response from another module and that module or computer sets a code for no response. The technology is just not there yet to get all of the computers on a car to communicate in a timely manner and get each computer to recognize that fault.

How do I replace the computer chip that controls the gauges and sensors on my Buick Lacrosse?

What computer chip ? Your vehicle has up ten computers on the vehicle . PCM - engine control module , BCM - body control module , SRS - air bag control module , EBCM - electronic brake control module , The instrument cluster has a microprocessor inside , the heater / A/C control panel is a control module .All the control modules on your vehicle are connected on a serial data communication network .
There are 2 different communication networks on this vehicle: The class 2 network and the GMLAN network. The class 2 serial data circuit is the low speed link, and the GMLAN serial data circuit is the high speed link. Modules that need real time communications are attached to the high speed network. The engine control module (ECM) is the gateway between the networks. The purpose of the gateway is to transfer information from one network to another.
When one of these modules is changed it needs to be programmed , unfortunately the dealer is the only place to have it done at. A GM factory scan tool is needed to do the job ! If it's not done correctly the whole vehicle network will lock up, making the vehicle inoperable .
Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate and share data with each other:
Body control module (BCM)

Digital radio receiver

Electronic brake control module (EBCM)

Engine Control Module (ECM) (LY7)

Instrument panel cluster (IPC)

HVAC module

Powertrain control module (PCM) (L26)


Inflatable restraint sensing and diagnostic module (SDM)

Vehicle control interface module (VCIM)

The GMLAN serial data communications circuit used on this vehicle is in a linear topology. The following modules are connected to the link, in order from DLC to the end of the linear configuration:
The following modules communicate on the GMLAN serial data circuit:
The transmission control module (TCM), (LY7) 3.6-L

The engine control module (ECM), (LY7) 3.6-L

I very strongly suggest you don't try to fix this problem !

What is an ECM

Electronic Control Module, the engine management computer in plain English, the brain box in slang; some car makers call theirs an ECU (Electronic Control Unit), or a PCM (Program Control Module, or Powertrain Control Module), or ECM (Electronic Control Module). May even be other names for them. The engine computer uses several sensors (as inputs) to compute fuel requirements and spark timing (ignition timing) needed for the operating conditions at that moment, then it sends signals to controllers and switches (outputs) to run the engine at optimum efficiency.

  • A B.C.M. is................
    A body control module is a computer component in an automobile that checks, regulates and operates electronic devices throughout the car. When electric devices first began being used in cars and trucks, each device was governed by a separate electric component. There was a module for the air-conditioning, a module for the interior lighting, a module for the door locks, and so forth. A body control module gathers all these separate modules under one system so that they function together instead of separately, a format easier to both manufacture and troubleshoot.
  • While there are many different types of body control modules, they are generally alike, connecting sensors, switches and automatic reactions together in one computer system. These components are divided into inputs, such as sensor data about heat or speed, and outputs, or ways in which the body control module computer responds to control the vehicle's electronic functions. Inputs and outputs are further divided into analog and digital types of information--analog signals being used with modules that may change continuously (such as oil pressure) and digital signals being used for modules that can simply be on or off (like the headlights or the oil indication light).
Inputs and Outputs
  • Input components are divided into electric parts, such as the potentiometer, the variable resistor, the magnetic pickup and the voltage generator. A potentiometer is designed to change a voltage output to the computer, so that when a fuel setting or gas-pedal position is changed, the voltage will change and the computer will read the new voltage and respond accordingly. The variable resistor works in a similar fashion, but senses changes in temperature for reading engine coolant conditions and other data. The magnetic pickup reads the speed of a rotating object via a simple magnet attached to the object, and a voltage generator sends out a voltage signal based on the presence of compounds like oxygen so the computer can tell the oxygen-rich levels of a pipe or space.
    Output devices consist of relays, solenoids, servomotors, switching transistors and others. Relays can turn other devices on and off by connecting or disrupting a circuit to turn on a fan or automatic air conditioning unit. Solenoids are analog components that use magnetic forces to move objects, such as fuel injectors. A servometer is a mini-motor also used to move objects, usually to turn things, while a switching transistor is the digital version of a relay. Other output devices can be very simple, such as LED lights, or very complex, such as a night-vision view of the road.
Computer Tasks
  • The body control module computer performs many of the functions of a normal computer, including storing data, using RAM and sending or receiving radio waves. The computer regulates many of the systems and troubleshoots all its component modules. Some modules are set by timer, which the computer digitally keeps track of, while other modules--like the anti-theft alarm--need to be active even when the car is turned off. The body control module computer also can be in charge of keeping track of mileage and CO2 output.
    When troubleshooting, a mechanic often is pointed to the right area by the body control module system, which sends out a code that shows what module is not responding. At times, the body control module computer can diagnose itself and report specific problems.

Need the wiring schematics for a 2001 oldsmobile aurora

There are several computer modules involved in your antitheft and security system.
There is the Driver's door module, the right front door module, the right rear door module, the left rear door module, the dash integration unit, the rear integration unit, the instrument panel cluster, the theft deterrent module, the theft deterrent exciter module, the body control module and the powertrain control module. These are all networked together to form the perimeter security and anti-theft system.

Any problems you may be having with this system should be properly diagnosed. Diagnosis of this system must BEGIN with a complete scan of the onboard computer network so that fault codes can be retrieved. and the computer data checked and verified. This is the only way to correctly determine which part of the system is malfunctioning.

Wiring schematics are not designed to give you the location of these components. They only show the wiring connections that are made between them.

When turning the key it would start sometimes but die right out. Other times you had to hold the key in the on position for 10 seconds or so and it would start. Headlights would sometimes flash and car...

I have seen similar "crazyness" caused by communications problems in the computer network. If you scn your entire computer network you will most likely find several "U - codes" (U1000, U1006, etc.) which indicate that modules are losing communication with other modules within the network.

These type of problems are usually caused by a faulty charging system (sulfated, shorted battery, bad alternator diodes, Loose/corroded battery cable connections, etc.) or loose or corroded connectors at one or more of the computer modules.

Scanning your computer network would be the place to start. The modules like to tell on one-another. For example: if the communication loss is in the body computer, the engine control module and/or the instrument panel module, and/or the antilock brake module will have codes saying that the body control module was/is not communicating. In this example, I would take a hard look at the connectors at the body control module.

If several of the modules are all reporting loss of battery voltage at the module, then I would suspect a battery cable, bad ground circuit, etc. Please note that the engine control module will usually NOT report this type of code because it does not use capacitors to keep it "alive" with the battery disconnected like some of the modules such as the body control module and the passive restraint module.

No spark! replaced the crank position sensor, plugs, wires, ignition control modual. had the coil packs checked all ok.

This sounds like a bad computer, if your sure the coilpacks are good and you replaced the module and the new module is good and the wiring to the module is good then i would say the wiring to computer or bad computer, this module and coils are hidden in the rear of the motor and go bad often but if say there all good then my next step would be the computer,
