Service charging system message came on, took it to dealer checked it said body control module, so they replaced it. But didn't fix anything. Sometimes voltage meter show it's charging and sometimes it doesn't. Blinkers blink fast and are dull, at night tail lights don't work. It did this before and after the body control module was changed.

2007 pontiac g5 gt just had ignition replaced due to recall now 48 hours later it wont start. . battery fully charged


ignition replaced ???? Ignition switch , the electrical part or key lock cylinder and key ? left switch on 10 minutes ???? That won't work on your vehicle ! Light's lit on insturment cluster ? Car with padlock symbol ,check engine ,service engine soon etc.... The starting system on your vehicle is computer controlled as many fuctions are ! The ignition switch is a low voltage input to the BCM - body control module . Your best bet , take it back to the dealer .

Safelock on 2006 Pontiac Torrent. Randomly prevents starting. Seems to reset after a day or so. Is there a way to disable


It is the passlock system not safelock An you can't just disable it . It is software program into the BCM - body control module an the PCM - powertrain control module .Simply disconnecting the wires from the ignition to the BCM will render your vehicle useless . If an when the security symbol light is on you need to have it checked for DTC'S - diagnostic trouble codes . A GM dealer ,Chevy , Buick , Cadillac etc.... we know Pontiac is no longer around. Everything will work except the PCM will not let the fuel injectors work .
Passlock?"¢ System
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent system is provided in order to prevent the vehicle operation if the correct key is not used in order to start the vehicle. The ignition key allows the lock cylinder to rotate. The cylinder rotation produces an analog voltage code in the Passlock?"¢ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a serial data message is sent from the BCM to the powertrain control module (PCM). The message enables the fuel injector operation.
The design of the Passlock?"¢ system is to prevent vehicle theft by disabling the engine unless the ignition lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the Passkey system. However, the Passlock?"¢ system eliminates the need for any key mounted components. The components of the Passlock?"¢ system are as follows:
?€¢
The ignition lock cylinder


?€¢
The ignition switch


?€¢
The Passlock?"¢ sensor


?€¢
The BCM


?€¢
The security indicator


?€¢
The PCM

My 2003 impalas traction control wont shut off tried a new switch it has new hubs on it any ideas


Before replacing parts there is a specific way to start diagnostics an a professional grade scan tool is a must ! a code reader can not access the body control module , or the EBCM - electronic brake control module or instrument cluster ! All these modules communicate on the class 2 serial data bus.
Begin the system diagnosis with Diagnostic System Check - ABS . The Diagnostic System Check will provide the following information:
?€¢
The identification of the control modules which command the system


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


?€¢
The identification of any stored diagnostic trouble codes (DTCs) and their status

The use of the Diagnostic System Check will identify the correct procedure for diagnosing the system and where the procedure is located.
The traction control switch is a input to the body control module, with a scan tool hooked up an looking at BCM data ,check for conformation the traction control switch is turning on an off !
SERVICE TRACTION SYSTEM The IPC illuminates the SERVICE TRACTION SYSTEM indicator in the message center when the electronic brake control module (EBCM) detects a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination. The SERVICE TRACTION SYSTEM indicator illuminates for 60 seconds when the condition is present. The IPC sends a class 2 message to the radio in order to activate an audible warning.
TRAC OFF The IPC illuminates the TRAC OFF indicator when the following occurs:
?€¢
The electronic brake control module (EBCM) inhibits the traction control system due to a malfunction in the traction control system. The IPC receives a class 2 message from the EBCM requesting illumination.


?€¢
The body control module (BCM) detects that the traction control switch has been pressed (signal circuit is low). The BCM sends a class 2 message to the EBCM in order to disable traction control. The IPC receives a class 2 message from the EBCM requesting illumination. The BCM sends a class 2 message to the radio in order to activate an audible warning.

2009 Pontiac G5 remote start not working


Hooking up a factory tech 2 scan tool an checking BCM -body control module DTC'S - diagnostic trouble code's ,an input data for the remote start system . Would be the first step in the diagnostic procedure .

Circuit/System Description
Remote vehicle start (RVS) begins as an RF message received by the remote control door lock receiver (RCDLR) from a keyless entry transmitter. The RVS request is sent by the RCDLR to the body control module (BCM) via serial data. The BCM monitors system conditions such as content theft deterrent (CTD), hood ajar status, and body DTCs to determine if an RVS event will occur. If conditions are determined to be acceptable, the RVS message is sent to the engine control module (ECM). The ECM monitors system conditions such as engine control parameters and vehicle theft deterrent (VTD) to determine if engine starting will be allowed. If conditions are acceptable, the ECM will initiate engine starting. During the engine run time in a RVS attempt, before the operator enters the vehicle, the ECM may discontinue engine operation if system conditions require it or a message is received from the BCM requesting the engine be turned OFF.

Service variable effort steering on 04 Pontiac gp


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL, CEL and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System, MIL Malfunction Indicator Lamp, CEL Check Engine Light.

Code: U0140-LOST COMMUNICATION WITH BODY CONTROL MODULE What does this mean?


U0140 Lost Communication With Body Control Module

This generic "U" trouble code applies to all car makers and indicates a problem between the PCM and the body control module. This is likely the result of a problem in the data link between the two modules.

Is the U0140-LOST COMMUNICATION WITH BODY CONTROL MODULE also set?
YES: Follow the diagnostics for U0140-LOST COMMUNICATION WITH BODY CONTROL MODULE
Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test
NO: Replace and program the Powertrain Control Module.
Perform the POWERTRAIN VERIFICATION TEST. See: Verification Tests\Powertrain Verification Test

Good luck.
