I have 2005 Silverado. I tried to get an inspection, but the tech said that the diagnostic module is not reposding/working. He said that this connection is usually linked to the cigarette lighter(s), but after checking the schematic of the fuse panel I cannot find the fuse that controls the cigarette lighters. Can you give an idea?

I could see one window not working from a broken wire inside the door flex , but not both back windows . Back windows are controlled by LF door module . Both back windows have different grounds - LR G200 an RR G201 . Also both rear window switches have different power supply's .RR switch fuse # 18 30 amp . LR is fuse b# 9 40 amp . Both window motors or switche's going out at same time ???? wouldn't think so .

• Driver door module circuits open/shorted.
• Loose, corroded connectors.
• Damaged window regulator control switch.
• Damaged window regulator electric drive.
• Open fuse in fuse junction panel Fuse 39 (10A), 28 (10A), 30 (10A).

  Inspection and Verification
  
  1. Verify the customer's concern by operating the power windows/heated back window to duplicate the condition.
  1. Inspect to determine if one of the following mechanical or electrical concerns apply:
     
     
     VISUAL INSPECTION CHART Mechanical Electrical
     • Front door power window regulator damaged.
     • Front window run damaged.
     • Front door window glass out of window run.
     • Front door window glass broken.
     • Driver door module circuits open/shorted.
     • Loose, corroded connectors.
     • Damaged window regulator control switch.
     • Damaged window regulator electric drive.
     • Open fuse in fuse junction panel Fuse 39 (10A), 28 (10A), 30 (10A).
     • Open fuse in power distribution box Fuse 9 (40A), 10 (40A), 8 (40A).
     • Scratched grid.
  1. If inspection reveals an obvious concern that is readily serviced, correct the concern before continuing with Inspection and Verification.
  1. If the concern remains after inspection, connect the Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent to the data link connector (DLC) located beneath the instrument panel to perform DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the driver door module, go to Pinpoint Test A . If the NGS responds with NO RESPONSE/NOT EQUIPPED for the lighting control module, go to Pinpoint Test B . If the DATA LINK DIAGNOSTICS test is passed for the drivers door module and lighting control module, retrieve continuous DTCs and execute Self Test Diagnostics for the driver door module and lighting control module to retrieve current DTCs.
  1. If self test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics.
  1. If DTCs are retrieved, go to the Driver Door Module (DDM) Diagnostic Trouble Code (DTC) Index or Lighting Control Module (LCM) Diagnostic Trouble Code (DTC) Index to continue diagnostics.
  1. If the driver door module cannot be accessed by the NGS, GO to Pinpoint Test A . If the lighting control module cannot be accessed by the NGS, go to Pinpoint Test B .
  Rotunda Service Bay Diagnostic System (SBDS®) 001-00001 may also be used to diagnose this system.

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

1. If the concern remains after the inspection, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the program card is correctly installed.
   • check the connections to the vehicle.
   • check the ignition switch position.

1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.

1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
   • CAN circuit fault; all electronic units no communication/not equipped, refer to Section 418-00 .
   • No response/not equipped for instrument cluster, Go To Pinpoint Test A .
   • System passed, retrieve and record the continuous DTCs, erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster.

1. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index, the Restraint Control Module (RCM) Diagnostic Trouble Code (DTC) Index, or the Generic Electronic Module (GEM) Diagnostic Trouble Code (DTC) Index.

1. If no DTCs related to the concern are retrieved, GO to Symptom Chart to continue diagnostics.

Did you consider that the control module may not be commanding it to shift . The E in 4l60 E stands for electronic . Did you check for DTC'S - diagnostic trouble codes .
Diagnostic Starting Point - Automatic Transmission
Begin the system diagnosis with Diagnostic System Check - Vehicle . The Diagnostic System Check provides the following information:
?€¢
The identification of the control module or modules which commands the system

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

?€¢
The identification and status of stored DTCs

The use of the Diagnostic System Check - Vehicle identifies the correct procedure for diagnosing the system and the procedure location.
Symptoms When it has been determined through Diagnostic System Check - Vehicle that no DTCs are present, begin symptom diagnosis by reviewing the Transmission Component and System Description . Reviewing the Transmission Component and System Description information enables you to understand the operation of the system. This helps you determine if the condition described by the customer is normal or if a malfunction exists. If it is determined that a malfunction exists, identify the concern by referring to the table Symptoms - Automatic Transmission . The table Symptoms - Automatic Transmission provides common diagnostic categories which relate directly to diagnostic information or procedures.

There are a great deal of components involved here an the best way to tell what's working or not is have a scan tool hooked up to check for DTC'S - diagnostic trouble codes !
There is a lot

I am in the UK, so do not know this model, but I am a Bosch service tech and can tell you, if you have air in the ABS unit itself, you well need to connect to diagnostic tool with bleeding/venting program on it. The ABS pump needs to run and operate the solenoids to get the air out...

I am not sure if it was mine I would unhook positive let it sit for ten minutes or sow maybe it would reset or go to auto parts store they do diagnostics free

First of all you need to get this problem fixed ASAP. While the airbag light is illuminated, your SDM (Sensing and Diagnostic Module aka: the brain of your airbag system) shuts of power to the airbags. In which, if you are in an accident your airbags will not deploy while this light is illuminated. You need to take your vehicle to a GM dealership. A Tech 2 scantool is needed to retrieve the code from the SDM. Hopefully it won't be a costly repair, but is something that defineatly needs to be corrected soon. Good luck and hope all works well.

2002 taurus. don't have 2005. Sorry.

Could be your GEM module. Call your dealer and ask if your 2005 has GEM module. It's expensive so be sure it is problem first.

Dealer can test with NGS tool.

CAUTION: Once the new module is installed, it is necessary to download the module configuration information from the diagnostic tool equipment into the new module. For additional information, refer to Section 418-01 .

Principles of Operation
The generic electronic module (GEM) constantly monitors its subsystems for concerns. If a concern is found in one of the subsystems, the GEM will record the concern in the form of a diagnostic trouble code (DTC).
The ignition switch position is very important to the GEM functionality. Erratic or unexpected GEM functions can often be traced to problems with these ignition GEM inputs.
The GEM controls a variety of systems:

• windshield wipers
• courtesy lamps
• warning chimes
• keyless entry
• interior and exterior lamps
• power windows
• parking brake actuator warning chime
