Can't identify indicator light on instrument cluster

One of the contacts for the turn signal bulbs inside the instrument clusters is loose and may need resoldering. You will need to open up the cluster and check for continuity from the turn signal LED bulbs to the electrical connector plug. In our case, we found an open circuit.
Follow this procedure to troubleshoot this problem.

1. Remove instrument cluster from the dashboard.
2. Open the instrument cluster. Remove the back cover from the instrument cluster.
3. Once the circuit board is exposed inspect the contact where the turn signal sockets are connected to the circuit board. In our case one of the turn signal socket pins was broken and not making contact with the circuit.

Did you clear codes ? . All codes in the theft deterrent module must be cleared for a relearn.
PASSLOCK Changing - Components Description
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
Engineers design the Passlock™ system in order to prevent theft even if the various theft deterrent parts change. The Tamper mode will engage if any of the following components change:
• The Passlock™ lock cylinder
• The instrument cluster
• The powertrain control module (PCM)
If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, repeat the long tamper cycle from the beginning.
Are there any codes ?

No other messages in the driver info center ?
This section provides an overview of the instrument cluster operation as well as a detailed diagnosis. The instrument cluster serves as the primary interface for the vehicle's driver.
The instrument cluster contains a microprocessor as part of the instrument panel assembly. The instrument cluster performs the following functions:
• Recognizes operational malfunctions
• Alerts the driver through indicators
• Stores DTCs which identify malfunction areas
In order to perform all of these functions, the instrument cluster microprocessor has its own inputs, outputs and program software. The instrument cluster has the capability to diagnose malfunctions in the following components:
• The sensors
• The input switches
• The components
• The systems the instrument cluster communicates with or controls
When the instrument cluster or another microprocessor-controlled module detects a malfunction, the instrument cluster may turn on an instrument cluster indicator in order to alert the driver that a malfunction has occurred. Some indicator lamps have dual controls. Your best bet is have it checked for DTC'S diagnostic trouble codes !

What alarm ? Anti-theft ?
The theft deterrent system on this vehicle is comprised of 2 separate systems, the Vehicle Theft Deterrent (VTD) System and the Content Theft Deterrent (CTD) System. The VTD prevents drive away theft by preventing the vehicle from starting. The CTD is the vehicle alarm system which discourages unauthorized entry into the vehicle. These systems are described and diagnosed separately within this section.
SECURITY Indicator
The SECURITY indicator on the instrument panel cluster (IPC) is controlled by the body control module (BCM) through the security indicator control circuit.
?€¢
The Vehicle Theft Deterrent (VTD) System contained in the BCM commands the instrument cluster to control the SECURITY indicator only when the ignition switch is ON. The VTD System uses the telltale as a malfunction indicator.

?€¢
The Content Theft Deterrent (CTD) System also contained in the BCM commands the instrument cluster to control the indicator only when the ignition switch is OFF. The CTD System uses the SECURITY indicator to identify system status.

It's software , a program inside the BCM ! An you can't just replace the BCM , it needs programming ! The dealer is the place to have that done ,most of the time ! If there is a SECRUITY light lit on the dash ,there is a DTC - diagnostic trouble code stored in the BCM , this code will point the service technician in the diagnostic path !

All of the instrument cluster functions are handled inside of the cluster. So for just the gauge needles not lighting up, you will need a replacement instrument cluster.

This solution will be of great help to you,even in the case of future or other dashboard problems;
Instrument cluster consists of electronic analog gauges, various warning lights, and optional tachometer. Vehicles equipped with tachometer have an electronic vacuum fluorescent transmission range indicator (PRND3L),odometer and trip odometer display. Vehicles without tachometer are equipped with a cable-operated transmission range indicator.
Instrument cluster is equipped with the following warning lights:
Battery voltage.
Cruise (speed control).
Door ajar.
Fasten seat belt.
Lift gate ajar.
Low fuel level.
Low windshield and washer level.
Traction Control.
The Body Control Module (BCM), which receives input from various sensors, sends display information to instrument cluster and operates gauges. Instrument cluster incorporates a self-test diagnostic feature to identify electronic problems. BCM, Powertrain Control Module (PCM), and Transmission Control Module (TCM) are continuously monitored by the diagnostic system.

SELF-DIAGNOSTICS
With ignition off, press and hold TRIP and RESET buttons while turning ignition switch to ON position. Continue to hold TRIP and RESET buttons until odometer window displays CODE (approximately 5 seconds). If problem exists, system will display diagnostic trouble codes. See DIAGNOSTIC CODE CHART table. If no problem exists, Code 999 (end test) will be displayed.

CodeDescription
110.......Cluster Memory Fault
111.......Cluster Calibration Fault

After diagnostic code display ends, instrument cluster will go into each of the following tests in order:
Dim test.
Calibration test.
Odometer segment test.
Electronic Transmission Range indicator segment test.
Dim Test
CHEC-0 will be displayed in odometer window. Instrument cluster will dim Vacuum Florescent (VF) display. If VF displays do not dim, a problem in instrument cluster exists. See BODY CONTROL COMPUTER TESTS in BODY CONTROL COMPUTER article.
Calibration Test
CHEC-1 will be displayed in odometer window. Each of instrument cluster gauges will move sequentially through each calibration point. See GAUGE CALIBRATIONS table. If gauge needle is not calibrated properly, a problem in instrument cluster exists.

Odometer Segment Test
CHEC-2 will be displayed in odometer window. Each segment of odometer will light sequentially. If any segment does not light, replace instrument cluster.
Electronic Transmission Range Indicator Segment Test
CHEC-3 will be displayed in odometer window. Each segment of electronic transmission range indicator will light sequentially. If any segment does not light, replace instrument cluster.

Hey.
Don't drive anywhere til you check your coolant level . I think you'll find that you are very low on antifreeze. Check the rad cap while the engine is COLD, hate to see you get scalded by hot fluid.
Good luck
