Isuzu KB P190. Manual - part 1106

7A2-140   TRANSMISSION CONTROL SYSTEM (JR405E)

• Electrically Erasable Programmable Read Only

Memory (EEPROM)
This type of memory allows selected portions of
memory to be programmed while other portions
remain unchanged.
Certain learned values reside in the EEPROM,
such as:

- The vehicle identification number (VIN)

- The software/ calibrations identification

numbers

- The control module security information

• Flash Read Only Memory-Flash Memory

Flash memory has increased memory storage capacity.
During programming, all information within this type of
memory is erased, and then replaced with entirely new
information.

Service Programming Methods

The two methods of programming a TCM are listed
below:

• Remote Programming

• Pass Thru Programming

For information on programming a TCM using one of
the methods listed above, refer to Service
Programming System (SPS) (Remote Procedure) or
Service Programming System (SPS) (Pass-Thru
Procedure).

Before Programming a Control Module

Important: DO NOT program an existing TCM with the
identical software/ calibration package. This procedure
is not a short cut to correct the driveability condition.
This is an ineffective repair. An TCM should only be
programmed when the following occurs:

• When a service procedure instructs you to replace

the TCM.

• An updated software/ calibrations is released.

Ensure that the following conditions are met before
programming a TCM:

• The scan tool PCMCIA card is programmed with

the latest software.

• The TIS 2000 is installed with the latest software.

• The hardware key is plugged into the computer

port.

• Vehicle system voltage:

- There are no charging system concerns. All

charging system concerns must be repaired
before programming the TCM.

- The battery voltage is greater than 12 volts but

less than 16 volts. The battery must be fully
charged before programming the TCM.

- A battery charger is NOT connected to the

vehicles battery. Incorrect system voltage or
voltage fluctuations from a battery charger may
cause programming failure or TCM damage.

- Turn OFF or disable any system that may put a

load on the vehicles battery. Turn OFF or
disable systems such as:
◊ Heating, ventilation, and air conditioning

(HVAC) systems

◊ Headlights
◊ Room lights
◊ Accessory equipment

• The ignition switch is in the proper position. The

scan tool prompts you to turn ON the ignition, with
the engine OFF. DO NOT change the position of
the ignition switch during the programming
procedure unless instructed to do so.

• All tool connections are secure:

- The RS-232 cable

- The connection at the DLC

- The voltage supply circuits

• DO NOT disturb the tool harnesses while

programming. If an interruption occurs during the
programming procedure, programming failure or
TCM damage may occur.

• If you are performing the Pass-Thru programming

procedure using a notebook computer without the
power cord, ensure that the internal battery is fully
charged.

Service Programming System (SPS)
(Remote Procedure)

Notice: Some module will not accept SPS remote
procedure using 10MB PCMCIA card. In such case,
use 32MB PCMCIA card or SPS pass-thru procedure.
The Remote SPS method is a three-step process that
involves the following procedures:

1. Connecting the scan tool to the vehicle and

obtaining the information from the TCM.

2. Connecting the scan tool to the terminal and

downloading a new calibration file from the
terminal into the scan tool memory.

3. Reconnecting the scan tool to the vehicle and

uploading the new calibration file into the TCM.

Performing the Remote Procedure

1. Connect a scan tool to the vehicle and obtain the

TCM information using the following procedure:

Notice: Ensure the TCM is installed in the vehicle and
the battery is fully charged before programming.

a. Install a scan tool.

b. Turn ON the ignition, with the engine OFF.

c. Select Service Programming System (SPS) >

Request Info.

TRANSMISSION CONTROL SYSTEM (JR405E)   7A2-141

d. If there is already stored in the scan tool, the

existing data is displayed on the screen. The
scan tool asks user to keep existing data “Keep
Data” or “Continue” to request new vehicle
information from the TCM. If there is no data in
the scan tool, it will immediately start vehicle
identification.

e. Select the vehicle description by following the

on-screen instructions based on stamped VIN
or affixed VIN plate on the vehicle.

f. During obtaining information, the scan tool is

receiving information from all modules at the
same time. But only ECM information is
displayed on the screen.

g. Turn OFF all accessories and press “Okay”. 

h. Verify that the correct VIN is displayed on the

scan tool. If the VIN is incorrect or no VIN,
record the correct VIN.

2. Turn OFF the ignition.

3. Turn OFF the scan tool and disconnect from the

vehicle.

4. Transfer the data from the terminal to the scan tool

using the following procedure:

Notice: The TIS supports service programming with
the Tech 2 scan tool only.

a. Connect the scan tool to the terminal. 

b. Launch the TIS application.

c. Select the Service Programming System at the

main screen.

d. Highlight the following information on the Select

Diagnostic Tool and Programming Process
screen, then click “Next”.

• Select Diagnostic Tool - Tech 2

• Select Programming Process - Identify

whether an existing TCM is being
reprogrammed or a TCM is being replaced
with a new one

• Select ECU Location - Vehicle

e. Verify the connections on the Preparing for

Communication screen, then click “Next”.

f. Verify the VIN on the Validate Vehicle

Identification Number (VIN) screen, then click
“Next”.

Notice: If the TCM is replaced to new one, VIN does
not displayed. Input correct VIN reading from stamped
VIN or affixed VIN plate on the vehicle. If the TCM from
another vehicle is installed, input correct VIN by same
way.

g. Highlight Transmission on the Select System

Type screen, then click “Next”, if on-screen
instruction displayed.

h. Complete the following information based on

the service ID plate on the Validate Vehicle

Notice: Refer to Service Bulletin and Description
column before service programming is performed if the
bulletins are listed along with the calibration files.
Notice: Select Cancel if you receive a message stating
that the calibration selected is already the current
calibration in the TCM and reprogramming with the
same download is not allowed.

j.

Click “Reprog”.

k. The Transfer Data screen will appear until the

progress bar reaches 100%.

5. Close the application and return to the TIS

application selection screen after the download is
completed.

6. Turn OFF the scan tool and disconnect from the

terminal. 

7. Transfer the data from the scan tool to the TCM

e. Programming in Process will appear until the

progress bar reaches 100%.

Notice: Some warning lamp may turn ON or blink while
programming the TCM since communication between
the TCM and other modules are interrupted. Clear DTC
in any module after programming.

f. Press “Continue” and exit the program after the

scan tool displays “Programming Was
Successful”.

8. Turn OFF the ignition.

9. Turn OFF the scan tool and disconnect from the

vehicle.

Service Programming System (SPS) (Pass-
Thru Procedure)

Pass-Thru programming allows the scan tool to remain
connected to the terminal and to the vehicle throughout
the programming process. The vehicle must be in close
proximity to the terminal while using Pass-Thru.

1. Launch the TIS application.
