SOURCE: security light on 2004 chevrolet express van won't go off

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.

2009 gmc sierra showing code uo109


This is a generic communication system diagnostic trouble code that applies to most vehicle makes and models, including but not limited to Dodge, Ram, Chevrolet, Ford, GMC, and VW. This code means that the Fuel Pump Control Module (FPCM) and other control modules on the vehicle are not communicating with each other.

Code uo109


You must always give us Year, make and model of vehicle to give you more detailed information on known/recurring problems.
Normally UO109 code is loss of communication with the Fuel Pump Control Module FPCM.
Modules connected to the high speed General Motor Local Area Network (GMLAN) serial data circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. The modules have prerecorded information about what messages are needed to be exchanged on the serial data circuits, for each virtual network. The messages are supervised and also, some periodic messages are used by the receiver module as an availability indication of the transmitter module. The supervision time-out period is 250 ms. Each message contains the identification number of the transmitter module.

Possible Causes -
Faulty Fuel Pump Control Module Fuel Pump.
Control Module harness is open or shorted.
Fuel Pump Control Module circuit poor electrical connection

2004 chevy express van codes p0894


P0894 Transmission Slipping
P1258 Engine got Hot
P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

I'm getting code po894 for my 09 chevy express van 6.0L. Engine light is on and transmission jerks when going from 1st to 2nd gear, but only when engine warms up a little. Doesn't happen when


This one could be any of them. If you tackle this yourself start with the cheapest and move to the most expensive. The other way is to take this in for a diagnostic, pay them for that, and then fix it yourself knowing what it is for sure.

Whats the torque spec on cylinder head bolts for 1998 chevy express van 5.7L 350 v8 and it's a 1500 express


The torque specs are available in most shop manuals, but I'm sure you knew that already. There's no need to rush out and buy the shop manual if you don't want to. Go to www.autozone.com and register for free. Once registered you'll have access to repair manuals for your vehicle.
