Is it worth it to get an illuminated sign for my shop?

Hello Kammy ,you have electronic problems ! Your best bet would have it towed to a qualified repair shop .
SERVICE BRAKE SYSTEM
Refer to Brake Warning System Description and Operation !
The instrument panel cluster (IPC) illuminates the brake warning indicator when one or more of the following occurs:
• The body control module (BCM) detects that the park brake is engaged. The IPC receives a class 2 message from the BCM requesting illumination.
• The electronic brake control module (EBCM) detects a low brake fluid condition. The IPC receives a class 2 message from the EBCM requesting illumination.
• The EBCM detects an ABS malfunction which disables dynamic rear proportioning (DRP). The IPC receives a class 2 message from the EBCM requesting illumination.
• The IPC performs the bulb check at the start of each ignition cycle. The brake warning indicator illuminates for approximately 3 seconds before turning OFF.
• The IPC detects a loss of class 2 communications with the BCM or with the EBCM.

When there are electronic problems the computers will not allow the vehicle to start , hooking up a factory or professional scan tool to see what the problem is is the first place to start .

Hi Ced ,
The malfunction indicator lamp (MIL) is located in the instrument panel cluster. The MIL will display as either SERVICE ENGINE SOON or one of the following symbols when commanded ON:
Check engine ! The MIL indicates that an emissions related fault has occurred and vehicle service is required.
The following is a list of the modes of operation for the MIL:
?€¢
The MIL illuminates when the ignition is turned ON, with the engine OFF. This is a bulb test to ensure the MIL is able to illuminate.

?€¢
The MIL turns OFF after the engine is started if a diagnostic fault is not present.

?€¢
The MIL remains illuminated after the engine is started if the control module detects a fault. A diagnostic trouble code (DTC) is stored any time the control module illuminates the MIL due to an emissions related fault. The MIL turns OFF after three consecutive ignition cycles in which a Test Passed has been reported for the diagnostic test that originally caused the MIL to illuminate.

?€¢
The MIL flashes if the control module detects a misfire condition which could damage the catalytic converter.

?€¢
When the MIL is illuminated and the engine stalls, the MIL will remain illuminated as long as the ignition is ON.

?€¢
When the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition is cycled OFF and then ON.

You will have to take it to a shop so they can diagnose the problem. You need a certain computer to do this.

change the bulb you will half to take it to the shop

Toss it! Buy another one. Not worth fooling around with.

Sorry.

Oil light on is BAD. the engine may be toasted. Have a Shop check OIL PRESSURE.

The screen is actually illuminated by flourescent tubes. Most likely the ballast has died, this is not uncommon.

You can have the bulb and ballast changed but it is a complete pain to solder in the delicate bulb. Get a quote from a repair shop first as it may not be worth repairing.

hope this helps,

cheers

Did the same with my DW-003 and thought I'd broken the Illuminator (and the alarm didn't work). Next battery change was via a shop and the illuminator worked again (as did the alarm). This was just a battery cahnge, rather than a repair job - One of those things, I guess

Yes, there is illumination behind the heater control panel.

You need to remove the center inst cluster upper (radio) & lower finish (heater) panels to gain access to the heater control; the light socket is behind the heater panel.
