How can I fix my stabilitrak on my 2010 chev impala


What's wrong with it ? Need more info . Light on ? The first thing to do would be to have the vehicle checked for DTC'S - diagnostic trouble codes ! Get a diagnostic direction , not just replacing parts . Need a professional grade scan tool . Plus reading how stabilitrak works would also be a good Idea . StabiliTrak General Motors Stability Control

Vehicle Stability Enhancement System (VSES)
The vehicle stability enhancement system (VSES) adds an additional level of vehicle control to the electronic brake control module (EBCM).
Yaw rate is the rate of rotation about the vehicle's vertical axis. The lateral accelerometer measures the sideways acceleration of the vehicle. The VSES is activated when the EBCM determines that the desired yaw rate and lateral forces do not match the actual attitude of the vehicle.
The desired attitude of the vehicle are calculated from the following inputs:
• The position of the steering wheel
• The speed of the vehicle
• The lateral, or sideways acceleration of the vehicle
• Yaw rate of the vehicle
• Master cylinder brake pressure
The difference between the desired yaw rate and the actual yaw rate is the yaw rate error, which is a measurement of oversteer or understeer. If the yaw rate error becomes too large, the EBCM attempts to correct the vehicle's yaw motion by applying differential braking to the appropriate wheel. The amount of differential braking applied to the left or right front wheel is based on both the yaw rate error and side slip rate error.
The VSES activations generally occur during aggressive driving, in turns, or on poor road conditions, without much use of the accelerator pedal. When braking during VSES activation, the pedal pulsations feel different than the ABS pedal pulsations. The brake pedal pulsates at a higher frequency during VSES activation.

There a number of DTC'S that can set .
DTC C0035-C0050
DTC C0110
DTC C0131
DTC C0161
DTC C0179
DTC C0186
DTC C0196

DTC C0242 or P0856
DTC C0245
DTC C0292
DTC C0558

Do you know what DTC'S are , and a diagnostic flow chart ?

How do you put the resistor in the passlock system on a Oldsmobile Alero


You don't say if the security light is lit ? Is it ? If not , it's not a anti-theft system problem . An the passlock system on your vehicle the passlock sensor is part of the ignition lock cylinder . No resistor ! If the security light is lit you need to have it check for codes . There are a number of DTC'S that can set .
DTC B2947
DTC B2948
DTC B2957
DTC B2958
DTC B2960
DTC B3031
DTC B3033
DTC P1626
DTC P1630
DTC P1631
DTC P1632

The Passlock™ system is provided in order to prevent vehicle theft if the ignition lock cylinder is forced to rotate or the ignition switch is operated while separated from the ignition lock cylinder case. The body control module (BCM) provides security system sensor power and low reference for the Passlock™ sensor. The BCM also measures the security system sensor voltage.
When the correct key is used to start the vehicle, a magnet on the lock cylinder passes close to the Passlock™ sensor within the ignition lock cylinder case. The magnet activates the security hall effect sensor in the Passlock™ sensor which completes a circuit from the security sensor signal circuit through a resistor to the security sensor low reference circuit. The resistance value will vary from vehicle to vehicle. The BCM will measure the voltage on the security sensor signal circuit and compare this voltage to a previously learned voltage. If the voltage measured is within the valid range, the BCM will send a class 2 message to the powertrain control module (PCM) to enable vehicle starting. If the voltage measured is not within the valid range, a class 2 message will be sent to the PCM to disable starting of the vehicle.

95 sl500 check engine light reset and comes back on after it sits over night. any idea?


What code is it throwing ? Some codes are what are called two trip codes ! You clear the codes an start an drive the vehicle ,no check engine light . Park the vehicle over night an bam next time you start an drive the vehicle the check engine light comes back on .

??There are two types of DTC's, 1 trip DTC's and 2

trip DTC's

??A 1 trip DTC is for a condition that requires

immediate attention such as a catalyst damaging

misfire.

??A 2 Trip DTC is one that a condition must be found

during 2 consecutive trips such as an EGR fault.

??Most Monitors do not set a DTC and light the MIL

when a vehicle fails a test for the first time during a

DRIVE CYCLE. If a test is failed on a second

consecutive DRIVE CYCLE the MIL will light and a

DTC is stored in the vehicles powertrain control
module (PCM).

A bad CAN data circuit , no power or ground to the module ! Do you have any DTC'S
DTC U0001 High Speed CAN Communication Bus
Modules connected to the high speed GMLAN serial data circuits monitor for serial data communications on the high speed GMLAN network during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module detects a bus-off condition, a DTC U2100 will be set. This DTC can be retrieved as history only.

My top does not work


Diagnostic Starting Point - Roof (Folding Top)
Begin the system diagnosis with the Diagnostic System Check - Vehicle in Vehicle DTC Information. The Vehicle System Check will provide the following information:
?€¢
The identification of the control modules which commands the system


?€¢
The ability of the control modules to communicate through the serial data circuit


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of Vehicle System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
Have vehicle scanned for DTC'S . The power roof has a number of DTC'S that can be set ,could make diagnosing easier !

DTC B1010 08: System Sensors Data Mismatch signal invalid
DTC B1010 08 sets when the folding top control (FTC) module detects a switch is not in the proper state when compared to other switches. The conditions that cause DTC B1010 08 to set may also set other Folding Top DTCs. The position and direction of the folding top when the fault occurs will determine whether DTC B1010 08 will set or another Folding Top DTC will set. If any Folding Top DTCs between DTC B1296-DTC B3685 are set, diagnose those DTCs first. After diagnosing any other Folding Top DTCs, clear DTCs and operate the Folding Top to see if DTC B1010 08 resets before diagnosing it.

You best bet is to take your vehicle to a ASE certified repair shop or to a GM dealer .

What does code U0001 mean?


u0001 is set when there is a communication problem on the high speed can bus network . The ABS module sets this code. There are computers in the car that talk over a network and get information from other modules. The ABS module at one time did not get the information it need or there is no communication all the time.

DTC shows up on computer at auto zone as a bad code and i dont know what DTC means so i cant fix it if i dont know what it means so my question to you is what in the world does DTC mean ? Im working on a...


DTC stands for Diagnostic Trouble Code. My question is why did you have the vehicle checked out in the first place? Is the check engine light on? What was the code number and did it start with P0 or P1. If you don't remember then have the code(s) cleared and operate the vehicle until the code(s) reappear. The code or codes can help you to determine where to start looking.
