Why would the information panel in my car display, "Low fuel," "shocks inoperable," "service traction control," "do not exceed 80mpn," "service active handling," ect: and fuel gage reads empty?

Question edited for clarity

Take it to a good local auto-electrician as advised.

Have it checked for DTC'S - diagnostic trouble codes , before you start playing with thing's . All the gauge setting information comes to the instrument cluster over serial data network GM Class 2 from the PCM/ECM engine computer . Could have U codes stored, Do you know anything about serial data networks or U codes ? If not, do yourself a favor an have a qualified repair shop check it.

Fuel Gauge
The instrument panel cluster (IPC) displays the fuel level based on information from the engine control module (ECM). The engine control module (ECM) calculates the fuel level based on information from the fuel level sensor. The engine control module (ECM) sends the fuel level information to the body control module (BCM) via the serial data circuit. The instrument panel cluster (IPC) displays the fuel level as received from the BCM. The fuel gage defaults to E (empty) if:

• The ECM detects a malfunction in the fuel level sensor circuit.

• The IPC detects a loss of serial data communications with the BCM.

• The BCM detects a loss of serial data communications with the ECM.

When the fuel level is less than a pre-determined value, the Low Fuel indicator message illuminates.

Speedometer
The instrument panel cluster (IPC) displays the vehicle speed based on information from the engine control module (ECM). The engine control module (ECM) calculates the vehicle speed from the vehicle speed sensor (VSS) input. The ECM sends a serial data message to the BCM indicating the vehicle speed. The instrument panel cluster (IPC) displays the vehicle speed as received from the BCM via serial data circuit.

The speedometer defaults to 0 km/h (0 mph) when any of the following occur:

• The ECM detects a malfunction in the vehicle speed sensor.

• The BCM detects a loss of serial data communications with the ECM.

• The IPC detects a loss of serial data communications with the BCM.

the traction control is deactivated press the button to the bottom left of steering wheel to activate picture on button is triangle with a car and 2 swiggle lines display between speedo and rev gauge will inform when active

If the system fails to turn on or activate, the StabiliTrak®

light along with one of the following messages will be

displayed on the Driver Information Center (DIC):

TRACTION CONTROL OFF, SERVICE TRACTION

CONTROL, SERVICE STABILITRAK. If you see these

conditions, turn the vehicle off, wait 15 seconds, and then

turn it back on again to reset the system. If any of these

messages still appear on the Driver Information Center
(DIC), your vehicle should be taken in for service.

Before replacing parts there is a specific way to start diagnostics an a professional grade scan tool is a must ! a code reader can not access the body control module , or the EBCM - electronic brake control module or instrument cluster ! All these modules communicate on the class 2 serial data bus.
Begin the system diagnosis with Diagnostic System Check - ABS . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command 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 the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
The traction control switch is a input to the body control module, with a scan tool hooked up an looking at BCM data ,check for conformation the traction control switch is turning on an off !
SERVICE TRACTION SYSTEM The IPC illuminates the SERVICE TRACTION SYSTEM indicator in the message center when the electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The SERVICE TRACTION SYSTEM indicator illuminates for 60 seconds when the condition is present. The IPC sends a class 2 message to the radio in order to activate an audible warning.
TRAC OFF The 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 class 2 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 BCM sends a class 2 message to the EBCM in order to disable traction control. The IPC receives a class 2 message from the EBCM requesting illumination. The BCM sends a class 2 message to the radio in order to activate an audible warning.

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 BCM sends a serial data message to the EBCM in order to disable traction control. The IPC receives a serial data message from the BCM requesting illumination. The BCM sends a serial data message to the radio in order to activate an audible warning.
you need to have the ( EBCM ) electronic brake control module checked fro codes !

If the system fails to turn on or activate, the StabiliTrak light along with one of the following messages will be displayed on the Driver Information Center (DIC): TRACTION CONTROL OFF, SERVICE TRACTION CONTROL, STABILITRAK OFF, SERVICE STABILITRAK. If these DIC messages appear, make sure the StabiliTrak system has not been turned off using the StabiliTrak on/off button. Then turn the steering wheel clockwise from the nine o'clock position to the three o'clock position. If this clears the message(s), the vehicle does not need servicing. If this does not clear the message(s), then turn the vehicle off, wait 15 seconds, and then turn it back on again to reset the system. If any of these messages still appear on the DIC, the vehicle should be taken in for service.

I replaced my shocks with better quality... And now my Service Ride Control is also on. The mechanic said the truck is looking for the electronic switch on the previous shocks. There is a switch they can install to over ride the warning. Don't know if you had new shocks installed, but thought I would mention it.

You may have a wheel bearing that is going , causing the check traction controle light to display .
Or even a tire that is low on air pressure.... or brakes that need servicing...
Anything tire speed related will do ...

{: ) A car swerving light on the instrument cluster is the StabiTrak indicator, sometimes called the traction control indicator. A wrench beside it tells it requires servicing.

Your vehicle is equipped with StabiliTrak, which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions.
Traction control activates when the controller senses wheel spin. StabiliTrak will selectively apply the brakes and reduce engine torque to help regain traction.
Stability control activates when the controller senses a discrepancy between your intended path and the direction the vehicle is travelling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help guide the vehicle in the direction which you are steering.
When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to insure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. If driving conditions delay system initialization, the STABILITRAK NOT READY message may be displayed. If this is the case, your vehicle does not need servicing.
When the StabiliTrak system is both on and actively controlling the stability of the vehicle, the StabiliTrak light will blink for the duration of the event.
You may also feel or hear the system working. This is normal.
StabiliTrak will turn off automatically if a problem is detected in the system. The StabiliTrak light will come on and SERVICE STABILITRAK will be displayed on the DIC. For vehicles without a DIC, the StabiliTrak light and the StabiliTrak service light will both come on. If the SERVICE STABILITRAK message (or StabiliTrak service light) does not clear itself after restarting the vehicle, you should see your dealer for service.

check the brake fluid and make sure caliber is full of fluid. mine said that and it was because fluid was low.
