installed TIS 2000 with the latest software and
the hardware key is plugged into port.
b. Turn ON the scan tool and keep at title screen.
c. Launch the TIS application.
d. Select the Security Access at the main screen.
e. Highlight the “Tech 2” on the Diagnostic Tool

Programming > Program ECU.
8. Verify the VIN on the screen and follow the on-
screen messages. If not programmed or incorrect
VIN, input correct VIN.
9. Verify the fuel injector ID code on the screen and
follow the on screen messages. If not programmed
or incorrect ID cord, input ID code.
10. After complete the programming, turn OFF the
ignition for 30 seconds.
11. Start the engine and let idle.
12. Inspect for a proper engine running condition and
for no DTC's. Refer to Diagnostic System Check -
Engine Controls if needed.
Except Euro 4 specification
1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Select Diagnostics > appropriate vehicle
identification > appropriate engine model >
Programming > Download ID code. If the old ECM
cannot be communicated with a scan tool, select
Diagnostics > appropriate vehicle identification >
appropriate engine model > Programming >
Replace Injector and input 24 digits of each fuel
injector ID code.
4. Select VIN Programming. Verify the VIN on the
screen if programmed at previously described
SPS. If not programmed or incorrect VIN, input
correct VIN. In order to get programming approval,
the on-screen displays a message to user. Get
programming approval from the TIS 2000 using
the following procedure:
a. Connect a scan tool to the terminal that

G. Supply Pump Relearn
1. Install a scan tool.
2. Start the engine and let idle until engine coolant
temperature reads 65°C (149°F) or higher while
observing the Supply Pump Status parameter with
a scan tool. The scan tool parameter changes
status Not Learned > Learned.
Service Programming System (SPS)
Description
The service programming system (SPS) allows a
technician to program a control module through the
data link connector (DLC). The information transfer
circuit that is used at the DLC is the same serial data
circuit used by the scan tool for retrieving DTCs,
displaying data, clearing DTCs etc. This procedure
offers the ability to install software/ calibrations
matched to a particular vehicle.
Most control modules have two types of memory. The
software/ calibrations reside in the flash memory. The
two types of memory are listed below:
• 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.
