14791

The body control system consists of the body control module (BCM), communications, and various input and outputs. Some inputs, outputs and messages require other modules to interact with the BCM. The BCM also has discrete input and output terminals to control the vehicle's body functions. The BCM is wired to the GMLAN High speed serial data buss and the GMLAN Low speed serial data buss and acts as a gateway between them. If the BCM does not communicate the vehicle will not start due to the inability of the engine control module (ECM) and theft deterrent module (TDM) to communicate without the BCM providing the gateway function.

Power Mode Master

This vehicles BCM functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions.

Serial Data Gateway

The BCM in this vehicle functions as a gateway or translator. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss for communication between the various modules. The gateway will interact with each network according to that network's transmission protocol.

One example of this necessary communication is the communication between the ECM which is high speed serial data and TDM which is low speed serial data. If these modules can not exchange information, the vehicle will not start.

Communication between the BCM and a scan tool can be on the high speed GMLAN network or low speed GMLAN network. If one network is lost, the BCM can still communicate with the scan tool. A lost communication DTC typically is set in modules other than the module with a communication failure.

Body Control Module

The various BCM input and output circuits are described in the corresponding functional areas indicated on the BCM electrical schematics. Some BCM functions with the subsystems may be as a gateway only or as an enable for the system. The BCM related systems/subsystems include, but are not limited to the following:


• Antilock Brake System (ABS)
• Cruise Control System
• Exterior
led lights
• Horn System
• HVAC
• Instrument Cluster Indicator Control
• Interior Lighting
• Power Door Lock System
• Rear Window Defogger System
• Redundant Steering Wheel Controls
• Remote Function Actuation (RFA) control
• Retained Accessory Power (RAP)
• Shift Lock Control System - Automatic Transmission Shift Lock Control
• Starting System
• Supplemental Inflatable Restraint (SIR) System
• Vehicle Theft Deterrent and Immobilizer System

• Wiper/Washer System Functions


Thanks for sharing detailed information.. Just love the specifications but can you provide a short review abou the device..Waiting for reply thanks in advance:)

I am just wanting someone to clear up the fog light loom if my understanding of it is correct. Connector 86 from the relay goes to pin 11 connector 4, and pin 6 from the the foglight runs to pin 21 connector 3?

If this is correct what do you guys usually use for the pins. I cant seem to source suitable ones anywhere

If you can't find the pins, source an old harness (wreckers etc) with the correct pins & solder them to your harness. cheers

Is my interpretation of the wiring diagram correct?

Hi all.
Have a 2006 omega and upgrading fogs.
Wondering if anyone can help with pics of the switch from behind and confirm if its the number 6 pin on the switch is the fog active? Or a diagram would be great.
Any help would be awesome.
Cheers in advance

hi guys need full diagram for ve sv6 ecu and bcm not sure if bcm is the same pin out as others.
need to work out what to do, to get it to run by it self not sure if i can git to run or not.
holden will not help out with what i want.. Bosch computers from vz ve v6 are hard to do by the looks of it.
not sure if i can remove the VATS off the ecu before i pull it out of the car. or if you can at all.
i do a lot of mods on car and this is going in an old hi-lux
i do know of some one who can wire in the dash, bcm ecu, and i'm guessing he was going to do the key reader too. so it all works. also it"s auto so the sport shift will work to
$1200 was the price
but i know i can do it and want to.
so guys all the help i can get would be great, cheers thanks heap all for reading

0x01E -> 0x02E (Full 17 Digit VIN Number)
and
0x0F6 -> 0x106 (Full 17 Digit VIN Number)

I can also confirm that I am able to read from, and write to the EEPROM using the KeeProg EEPROM programmer using the above settings,
without having to remove the EEPROM from the board. (However I needed to remove the resin from the chip to make a good electrical contact).

(Will try the GQ-4X EEPROM programmer next, to see if it can read and write whilst on the board)...
For anyone that wants to play at home, the EEPROM location is here.

Hi great info top job Ive got a question I'm trying to find the location for the bcm sec code does anyone have an idea weee it may be

Not something I've actually looked for previously. Will probably need to know what that value is first before being able to search it in the eeprom dumps.
