Disable Stop / Start System

Post by mge.92 » Fri Jul 14, 2017 1:05 am

Been reading through the manual and think I found a way to disable the Stop / Start system I think.

ITEM DESCRIPTION
1 Battery Junction Box (BJB)
2 Quiescent Current Control Module (QCCM)
3 Rear Junction Box (RJB)
4 Voltage Quality Module (VQM) - Stop/Start system only
5 Startup battery
6 Battery Monitoring System (BMS) control module

VOLTAGE QUALITY MODULE - VEHICLES WITH STOP/START SYSTEM ONLY

E174480

ITEM DESCRIPTION
1 Voltage Quality Module (VQM)
2 Power connector
3 Ground connector
4 Signal connector
The Voltage Quality Module (VQM) is located adjacent to the Rear Junction Box (RJB) in the right side of the luggage compartment. The VQM is attached to the rear floor with three bolts. The VQM consists of a Direct Current (DC) - DC converter and an interface. This interface provides the communication with the Body Control Module/Gateway Module (BCM/GWM) assembly.

The DC - DC converter can produce a constant 12 V output voltage from the varying input voltage supplied by the battery during an engine restart. This constant 12 V output voltage is needed for the crucial vehicle systems.

The VQM supplies a constant voltage during an engine restart for the following:

The Instrument Cluster (IC)
The Quiescent Current Control Module (QCCM)
The infotainment system components - Depends on equipment
The Rear View Mirror (RVM) - If equipped
The Parking Assist Control Module (PACM) - If equipped
The Rear View Camera (RVC) - If equipped
The left and right Blind Spot Monitoring Control Module (BMCM) - If equipped.
The VQM has three connections:

Two power connectors:
A startup battery feed connection from the Battery Junction Box (BJB) via a 60 A fuse.
A power output connection to the Rear Junction Box (RJB) and to the Quiescent Current Control Module (QCCM).
An additional connector to provide electrical connection to the following:
Ignition signal from the BCM/GWM assembly.
Crank signal from the starter motor relay located in the left Engine Junction Box (EJB).
Status and diagnostic messages to the BCM/GWM assembly via the Local Interconnect Network (LIN) bus.
Ground.

Here you go. If you read through it, the ones with the active rear locking Differential have a module in the rear left side.

I'm just wondering does the lock symbol in the image (on the rear drive axle) indicate that the rear electrical (active) differential is present or does this symbol also show in the none active variant?
