a wagon vehicle.

X3-7 Rear Wiper

Request RR_WWPR_R This input normally comes from the rear wiper control switch fitted

to a wagon vehicle.

X3-8 Boot Unlock

Required BOOT_ULK This input connects to the rear compartment release button located

in the front storage compartment of a sedan or wagon vehicle.

X3-14 Rear Washer

Request RR_WWA_R This input normally req uests the rear washer to operate on a

wagon vehicle.

X4-2 Boot Solenoid BOOT_SOL

This output normally rel eases the rear compartment latch on a

sedan or wagon vehicle.

moved to the Door position.

X4-24 Stop / tail light

sense STLP_SENS This input normally se nses the amount of current drawn by the

stop and tail lamps.

Refer to Section 12J in the MY 2003 VY and V2 Series Service Information for further details about the functions of the

BCM.

BCM Wiring Differences

The MY 2004 AWD Crew Cab vehicle has identical BCM related electrica l wiring compared to MY 2003 VY and V2

Series vehicles expect for the follo wing differences:

BCM Terminal Wiring Change Description

Identifier Name Acronym MY 2003 VY and V2 Series MY 2004 AWD Crew Cab

X2-9 Secondary

Serial Data UART_SCD One connection of this terminal

goes to the A37 Brakes/Traction

module.

This terminal now connects to

the A38 Brakes/Traction module

in this vehicle.

X2-9 Secondary

Serial Data UART_SCD A connection from this terminal

goes to the A21 Memory Seats

module

No wiring exists in the Body

Wiring Harness (BWH) to

accommodate the A21 module.

Inclinometer (P2) Control Illumination

For a detailed description of how the vehicle’s inclinometer illumination system functions and ho w to adju s t its indicators,

refer to Section 12C Instruments in the MY 2004 AWD Wagon Service Information.

1.2 BCM TECH 2 Programming

BCM Programming

When a BCM is replaced for any reason, the previously installe d user settings must retrieved beforeha nd and

re-programmed into the replacement BCM using TECH 2. These preset factory defaults settings are l isted below:

Headlamp Off Delay .........................................................................................set to 1 second

Approach Illumination...................................................................................set to 30 seconds

Automatic Headlamp Sensitivity ..........................................................................set to Normal

Interior Courtesy Lamp Timeout ...................................................................set to 30 seconds

Interior Courtesy Lamp Timeout – Ignition Off..............................................set to 30 seconds

Intermittent Wiper Speed........................................................................................... set to On

Two Stage Unlock.....................................................................................................set to Yes

Auto Lock in Drive...................................................................................................... set to No

Door Lock Indication........................................................................................set to Indicators

Radio and Accessories Timeout....................................................................set to Door Open

NOTE

The above listed values can be retrieved from

the original BCM and then re-entered manually

using TECH 2, however it is best performed by

transferring the vehicle’s previousl y programmed

details into TECH 2 by using its LEARN feature

before the BCM is removed from the vehicle.

For details relating to BCM programming a nd how to enter

the required data, refer to Section 12C, 3.15 Program in the

MY 2003 VY and V2 Series Service Information.
