DISCONNECT THE ECU FUSE FROM YOUR FUSE BOX. WAIT 15 SECS AND THEN RECONNECT AND START YOUR VEHICLE.

Typically - Yes.
Some GM cars (and Mercedes) have the battery concealed and it offers a remote positive terminal for checking and charging.
You should connect to the positive terminal whenever possible. The negative side of the charger can be connected to any metal on the vehicle. Ground is ground - all over.

Bad voltage regulator. Check all battery connections and clean as needed of course.

Your evap canister is probably bad and the gas cap may just be loose, but these are not transmission codes.

unfortunately these trucks have defective instrument clusters. It is very common and I have replaced hundreds of clusters for this issue, the factory has extended the cluster warranty to 7 years or 70k miles whichever comes first, extended warranties usually cover it but charge a decuctible. if you are out on both of those you will have to have it replaced, or replace it yourself. it is replaced as an entire unit and is not serviceable(of course) thanks general motors.. you can get one from a wrecking yard and it will work, only drawback is your vehicle will display however many miles the vehicle it came out of had on it.. oh also their was another factory warranty extention on the cluster up to 80k miles, the drawback is between 70 and 80k they just pay for the part. I have removed the cluster and dis-assembled it carefully resetting all the needles but it didn't last long and was a waste of time

Hi,

This is a common problem and a technical bulletin is already published. Let me provide you the details :-

Bulletin No.: 05-08-67-002A

Date: September 28, 2005

INFORMATION

Subject:
Diagnostic Information and Reinitialization Procedures for a Sunroof Will Not Close Condition

Models:
2005-2006 Cadillac Escalade Models
2005-2006 Chevrolet Avalanche, Suburban, Tahoe
2005-2006 GMC Yukon Models

Supercede:

This bulletin is being revised to update the correction information. Please discard Corporate Bulletin Number 05-08-67-002 (Section 08 - Body and Accessories).

In the event that one of the following conditions occur, perform the reinitialization procedure listed below prior to following SI for diagnosis.

^ The sunroof module has driven the mechanism out of the rear of the assembly preventing the sunroof from closing.

^ The unit will not close fully.

^ The sunroof appears to be jammed or cycles forward and then stops early.


Sunroof Motor/Actuator Synchronization Procedure

Synchronization will be necessary any time the sunroof motor is removed from the unit. The sunroof module is synchronized when the motor controller learns the full vent position.

To synchronize the sunroof:

(Please read directions completely prior to beginning the procedure)

1. Turn ON the ignition with the engine OFF.

2. DO NOT OPERATE THE SUNROOF GLASS IN THE OPEN/TILT DOWN DIRECTION UNTIL THE INITIALIZATION PROCEDURE IS COMPLETE OR SERIOUS DAMAGE MAY OCCUR.

3. Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position. Even if the sunroof stops early, proceed to step 4.

4. Continue to hold the close/tilt up portion of the sunroof switch for at least 30 seconds or until you hear a slight click from the front of the sunroof mechanism.

5. The slight clicking noise at the front of the sunroof confirms the initialization is complete.

6. Verify that the system operates normally.

Once the synchronization is complete, the position of the motor and mechanism is stored in the memory of the sunroof motor controller. The motor controller retains this memory even if power is disconnected to the motor.


If reinitialization does not correct the concern, perform the following steps:

1. Reference SI and use the R&R procedure for removing the complete sunroof module assembly.

2. Remove the motor from the unit and force the Pin Guides forward until the hard stop is reached. If water channel guides are out of track, there may resistance to moving pin guides forward. If water channel guides are out of track you will need to feed them through the rear of track. Make sure both sides are in complete forward position. In the event track mechanism components are damaged, use Service Kit P/N 88979948.

3. Once the track mechanism is repaired, reattach the motor and follow the reinitialization procedure listed above.

4. Check for proper operation.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

This is a code for catalytic converter low efficiency. Usually, this code points to a bad catalytic converter but not always... since the rear (downstream) oxygen sensor could be bad (this is the O2 sensor after the catalytic converter). The oxygen sensors and circuits need to be tested to verify defect is actually the converter and not a sensor or circuit problem

disconnect all electrical wiring that is attached to the bed then disconnect the fuel filler tube. there is 4 bolts that hold the bed to the frame that you will have to remove. some trucks the bolts are removed from inside the bed and others from under the bed though the frame. then get help to pickup the bed and turn it to gain access to the pump or remove the bed from the frame.

I would point to either the thermostat sticking or the fan clutch going bad

Look at the label in the engine compartment (on radiator, fender, near fan shroud). This link will take you to a sketch of the belt routing diagram courtesy of Auto Zone for a 1500 2WD engine.

make sure ABS SNSORS ARE SET PROPERLY AGAINST TONE WHEEL, air gap is zero .for your brake light you need to reset brake pressure valve below master cylinder where all lines meet before going to abs modual ,an advanced scanner will determin what wheels are causing problem . good luck on it .

Probably the blend door sticking. It regulates the air in the cab.

2005 Chevrolet... | Answered on Jul 16, 2014


this indicates the catalytic convertor isn't working at correct values , this may be due to a leak in the air intake system or the exhaust system before the cat convertor , if no leaks found i'd recommend a fuel addative that cleans the catalytic convertor as well as the engine parts , take for a longish drive (50-100) at a highish speed to get to a high engine temperature , may have to do this a couple of times and rescan for code , if still showing code will need further investigation as to which sensor may need replacing
