Disconnect ground battery cable for 10 minutes( this resets the ECM ) then try to start the vehicle.

I have a 2000 buick century 3.1 my security light still staying on after i changed the key cylinder and the electrical key switch whatelse can that be ??


Having the vehicle checked for codes should have been the first thing done . Security light on ,a code is stored in the control module that controls the anti-theft system ! This is if you want it fixed right !
Important: If the wrong ignition key is used in an attempt to start the vehicle, a Data Trouble Code (DTC) will be set and the Body Control Module (BCM) will not send a fuel enable or starter enable message to the Powertrain Control Module (PCM) for three minutes even if the correct ignition is used.
The Pass-Key II® Theft Deterrent system prevents vehicle theft by disabling the starter motor and fuel system. If the Body Control Module (BCM) dose not identify the use of the correct ignition key to start the vehicle, the (BCM) will communicate a message to the Powertrain Control Module (PCM) which will disable the crank relay and fuel delivery to the engine.
When the (BCM) identifies the use of the correct ignition key (resistor pellet) to start the vehicle, the (BCM) will send a fuel enable and starter enable message to the (PCM) which will allow the vehicle to start.

DTC B2957 Security System Sensor Data Circuit Low
DTC B2958 Security System Sensor Data Circuit High
DTC B2960 Sec Sys Sensor Data Incorrect but Valid
DTC B3031 Security System Controller in Learn Mode
DTC B3094 No Response from ECM/PCM Received

or you can do a by pass that may or may not work ! You could measure the resistance of the pellet on the side of the key , then go to radio shack a by a resistor of the same value ! Then find the wires under the dash that come from the ignition switch ! Solder the resistor into the harness side wires , not going back to ignition switch . The wires break or contacts inside ignition switch do . You could check resistance with ohm meter . Put key into the ignition switch , find those wires i said about before . Check resistance at the wires under dash , is it the same resistance as pellet ?

HI,can a car who has fault service stab sys traction failed abs shown on their vehicle continue to drive it or does it need to be fixed as soon as possible. thank you for your reply


You can still drive it but the ride and safety will be affected. I recommend you get vehicle fixed at earliest as can. The vehicle will skid if hit brakes hard. Stability will also be affected

What does it mean when my 2008 trailblazer LT stabilitrac service light comes on?


Service Stability System Message The message center displays the service stability system message when any one of many VSES-disabling DTCs is set. The EBCM sends a serial data message to the IPC requesting this display.
It means there is a problem an till you get it fixed the stability control system is disabled ! ( EBCM ) electronic brake control module Has detected a problem an set a DTC - diagnostic trouble code in it's memory an had the message displayed !
Vehicle Stability Enhancement System (VSES)
The vehicle stability enhancement system (VSES) provides added stability during aggressive maneuvers. Yaw rate is the rate of rotation about the vehicle's vertical axis. The VSES is activated when the electronic brake control module (EBCM) determines that the desired yaw rate does not match the actual yaw rate as measured by the yaw rate sensor.
The desired yaw rate is calculated by the EBCM using, primarily, the following inputs.
?€¢
The position of the steering wheel


?€¢
The speed of the vehicle


?€¢
The lateral, or sideways acceleration of the vehicle

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. When a yaw rate error is detected, the EBCM attempts to correct the vehicle's yaw motion by applying brake pressure to one or more of the wheels. The amount of brake pressure which is applied varies, depending on the correction required. The engine torque may be reduced also, if it is necessary to slow the vehicle while maintaining stability.
VSES activations generally occur in turns during aggressive driving. When braking during VSES activation, the pedal may pulsate. The brake pedal pulsates at a higher frequency during VSES activation than during ABS activation.

1999 MERCURY VILLAGER BOGS WHEN GOING UP HILL WHEN ONLY 1/8TH TANK OF GAS FILLE IT UP AND THEN STILL BOGGED FOR ABOUT A MILE THEN QUIT BOGGING WHAT CAUSED THIS


when a tank is empty there is no fuel for the pump and the system runs low on fuel pressure Going up hill the fuel runs away from the pick up line and the pump sucks air
After filling it takes a while to empty the air out of the system to allow full pressure again. It is an extremely costly practice to run so low on fuel as it may lead to a pump replacement

check for a fuel leak along the line. some where you have a loose fitting ie at the fuel filter, fuel line that is allowing the fuel to drain back to the tank The angle of the vehicle shows that airis being sucked into the system somewhere

How to reset stabilitrak on a 2007 chevy equinox


Your vehicle has electric power steering !
The Electric Power Steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the power steering control module (PSCM), torque sensor, power steering motor rotational sensor, power steering motor, discrete battery voltage supply circuit, and the GMLAN serial data circuit to perform the system functions. The PSCM and power steering motor are each serviced separately from the steering column assembly. However, the motor rotational sensor is serviced as part of the power steering motor, and the torque sensor is serviced as part of the steering column assembly. The PSCM also monitors vehicle speed from the engine control module (ECM) via the GMLAN serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road feel and directional stability.
Stability System Indicator The IPC illuminates the stability system caution indicator when one or more of the following conditions exists. The EBCM sets any one of many VSES-disabling DTCs. The EBCM sends a serial data message to the IPC requesting illumination.
Traction Control System Indicator
TRAC OFF The instrument panel cluster (IPC) illuminates the TRAC OFF indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a serial data message from the EBCM requesting illumination.


?€¢
The Body Control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The Body Control module (BCM) sends a serial data message to the EBCM in order to disable traction control. The IPC receives a serial data message from the EBCM requesting illumination. The BCM sends a serial data message to the radio in order to activate an audible warning.


Your best bet is to take it to a ASE certified an qualified repair shop ,that has the diagnostic tool to fix this problem .

Car won't start on a hill


That is typically indicative of a fuel pump issue. It isn't necessarily the fuel pump itself, but the way it is positioned in the tank when low on fuel can keep it from getting fuel.
If you fill the tank and find however that the problem still exists then the other cause is related to parking.
Your Buick has a safety mechanism that will not allow it to be started if not fully parked, called the Brake Transmission Shift Interlock. Not only does this solenoid controlled component not allow you to shift out of park without applying the brake, you also will not be able to start it if this mechanism is faulty, or something in the gear select linkage prevents the shift selector from properly engaging the parked position. When on a hill and you shift into park, the vehicle weight is rolled against a component of this system, preventing it from properly "registering" the parked gear select position.
What you can do the next time you need to park on a hill is with your brake applied and the gear select in Drive, apply the emergency brake and hold it down, THEN shift into park. Then release your feet from the brakes. This should help.
