Prowler V6-3.5L VIN G (1999)
These vehicles use MMC based modules. The CH8432 Supplemental Reprogramming Tool (SRT) was shipped as a 2001 Essential Tool. The flash
reprogramming update files will be downloaded from TechCONNECT Client to the SRT for flash reprogramming sessions on these vehicles. Users
should closely follow the instructions that come with the tool. If the tool has not been initialized, there is a known condition where it may take up to 5 or
more attempts for it to fully initialize and become functional.
Once it has successfully flashed, it is initialized and no further action is required.
PREPARING TO FLASH
It is highly recommended that a sign, or other process, be used that notifies other users that a FLASH SESSION IS IN-PROGRESS and must NOT be
interrupted. Interrupting some flash reprogramming sessions at critical junctures can render a module inoperative. Another user may not realize that a
flash session is in-progress and may disturb or disconnect the DRBIII(R) or do something on the vehicle that could interrupt the flash process.
Before starting the flash session, read, record and erase all DTCs found on the vehicle.
Also "Cold Boot" the DRBIII(R) and download the flash since this will erase the flash file from the DRBIII(R) memory. (To "Cold Boot", press the
MORE and YES buttons on the DRBIII(R), at the same time. Then press "F4").
Be sure to arrange the TechCONNECT and DRBIII(R) so that no cables are stretched across an area where someone might trip over or kick a cable.
When setting up your DRBIII(R), insure that it rests on a surface where it will not fall or be bumped during reprogramming e.g.: DRBIII's have been
known to be swept off vehicle windshields by accident when a user bumps the wiper switch).
Check User settings on the DRBIII(R). From the DRBIII(R) Main menu, press 6,1 and check to make sure item 1. Echo on PC is set to OFF. On
occasion, when Echo on PC is set to ON, flash reprogramming errors may occur.
VEHICLE BATTERY VOLTAGE
The flash programming procedure puts a load on the electrical system that may last from five to twenty minutes depending on the particular flash
reprogramming update. Connect a battery charger to the vehicle. Set the charger to as close to 14 volts as possible. If the charger has a timer, set it for 30
minutes BEFORE starting a flash reprogramming session. This will help to prevent unwanted resets by either the DRBIII(R) and/or the vehicle module
that are caused by voltage fluctuations.
Alternately, as a bare minimum, use a "Battery Jump Box" when a battery charger is unavailable to ensure adequate and stable system voltages on the
module being flash reprogrammed.

Connected/Disconnected Flash Mode Using TechCONNECT
CONNECTED MODE FLASHING USING TechCONNECT
Capable but not recommended.
In this mode, the DRBIII(R) remains connected to the TechCONNECT Client and the vehicle throughout the flash session. The DRBIII(R) is connected
to the TechCONNECT Client using the GPIB (CH7035) cable and to the vehicle using the vehicle I/O cable (the CH7000A for most vehicles).
This mode is useful when the TechCONNECT Client is next to the vehicle being flashed.
Another advantage of this mode is that you are able to determine all available flash updates for the vehicle you are connected to by clicking on the "Read
Part Number(s) From Vehicle" button.
Again, it is important that other users do not attempt to reboot or move the TechCONNECT Client while a flash update is in-progress.
The reprogramming procedure of this mode is initiated by selecting the controller option and clicking "Download/Update" button on the
DISCONNECTED FLASH MODE
