    symptoms, when the brake pedal is partiallt depressed ie 1/2 wat all is fine, when fully depressed the left rear tail light goes out and the left turn goes out. the BCM 5 fuse does blow

    might have been caused by trailer wiring or bad BCM -- trailer wiring has been removed along with any other aftermarket accessories

There is no scan tool or test that will tell you a module is bad. It requires a highly knowledgeable look at all the inputs and outputs and analyzing of the data to determine if the module is responding correctly

Not sure about a body control module, there is a pcm under the hood on the pass. side that controls most everything on these, however i would check your fuses for the seat, on the 00 models the headlights do stay on all the time while driving due to daytime running lights but if they stay on after you take the key out then id check the headlight switch or sensor on the pass side dash.

2005 Chevy Silverado 3500. Automatic headlights turn on, the engine dies. Turn it off, it still keeps running, even when the key is pulled out.cannot find the wiring issue..... ANY HELP??


What code's ? # code's P0 what ? Any BCM - body control module code's ? Did you do diagnostic test's for said code's ? Do you know what a factroy diagnostic flow chart is ? Is the vehicle a 4X4 or 2X4 ? What engine ? Do you know what class 2 serial data bus is ? Do you have wiring diagrams ?
Headlamp ON/OFF control is determined by the body control module (BCM) by a signal on the headlamp switch headlamp on signal circuit when the headlamp switch is in the HEAD position. When the headlamp switch is in the AUTO position, the BCM determines headlamps ON/OFF by the voltage from the ambient light sensor.

High Beams
The high beam headlamps receive voltage from the headlamp HI relay located in the underhood fuse block. The body control module (BCM) controls the relay on the headlamp high beam relay control circuit. High beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is grounded, the BCM grounds the headlamp high beam relay control circuit, illuminating the high beam headlamps. The right and left high beam circuits are independent and are fused independently in the underhood fuse block. The right and left headlamps are grounded at G100 and G104.
The high beam indicator is illuminated when the instrument cluster receives a class 2 serial data message from the BCM that the high beams are illuminated.
Low Beams
The low beam headlamps receive voltage from the headlamp LOW relay located in the underhood fuse block. The body control module (BCM) controls the relay on the headlamp low beam relay control circuit. Low beam control is determined by a signal on the headlamp dimmer switch signal circuit from the multifunction switch. When the headlamp dimmer switch signal circuit is open, the BCM grounds the headlamp low beam relay control circuit, illuminating the low beam headlamps. The right and left low beam circuits are independent and are fused independently in the underhood fuse block. The right and left headlamps are grounded at G100 and G104.

DTC B2645
The body control module (BCM) monitors the ambient light sensor signal circuit in order to determine if the daytime running lights (DRL) or the auto headlights (ALC) should be turned ON in the AUTO mode. When the BCM senses the ambient light sensor signal voltage is between 1.75-4.9 volts, either the DRL will be commanded ON or the ALC will be commanded ON depending upon the amount of light received by the sensor.

Where is fuel filter on 2010 chevy express 6.0 liter V8.


2 of them........First Fuel Filter

One fuel filter is in the fuel pump of the Express Chevy 3500, which is used to push fuel or gasoline through the fuel line. The fuel pump is inside the gas tank. This fuel filter is a mesh or screen that prevents large foreign particles for entering the fuel pump. Access to the fuel filter is obtained by removing the fuel tank and then the fuel pump from the fuel tank.

Second Fuel Filter Location

The second fuel filter is within the fuel line itself. After the fuel pumps extracts fuel from the gasoline tank and into the fuel line, fuel flows through the line and through another filter on the driver's side of the Express Chevy 3500 under the front wheel suspension. This fuel filter cleans the small particles that escaped from the fuel tank.

Fuel Filter Types

The year of your Chevy Express 3500 determines what type of fuel filter is installed on the van. The fuel tank filter is always mesh or screen, but the fuel line filter can be of three different types. Two types are snap-on filters, while one type has clip-on ends.

Do you have a check engine light on? Have you done an engine control module fault code test (OBD2 control system), is fuel pressure OK under a load? Has the fuel injector spider manifold (inside the throttle bore) assembly been replaced, that is a known problem.

Will crank but will not fire


get a spark tester,if there is spark then there is a fuel problem.put fuel spray into the throttle body and see if it starts and dies out.
then it is the fuel pump perhaps.
there are crank and cam sensors that could be a problem. or the ignition module .best thing is to scan it and see if any codes show to point out the defective system.
