6E-276 Engine Control System (4JH1)
1. Connect the scan tool to the vehicle DLC, with theengine and the scan tool OFF.
2. Turn ON the scan tool.
3. Select Diagnostic > appropriate vehicle identification > Powertrain > 4JH1-TC >
Programming > Program VIN.
4. Input correct VIN reading from stamped VIN o
r
affixed VIN plate on the vehicle.
Select Lock ECU and lock the programmed VIN.

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 be
the scan tool for retrieving diagnostic trouble codes
(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 Onl
y
Memory (EEPROM).
This type of memory allows selected portions o
f
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 an engine control
module (ECM) are listed below: • Remote Programming
• Pass Thru Programming
For information on programming an ECM using one o
f
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 ECM with the identical
software/calibration package. This procedure is not a
short cut to correct the driveability condition. This is an
ineffective repair. An ECM should only be programmed
when the following occurs: • W hen a service procedure instructs you to replace
the ECM. W hen the ECM from another vehicle is
installed, VIN must be changed. And change
vehicle information as necessary such as type o
f
transmission.
• An updated software/calibrations is released.
Ensure that the following conditions are met before
programming an ECM: • 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 compute
r
port.
• Vehicle system voltage:
- There are no charging system concerns. All charging system concerns must be repaired
before programming the ECM.
- The battery voltage is greater than 12 volts bu
t
less than 16 volts. The battery must be fully
charged before programming the ECM.
-
A battery charger is NOT connected to the
vehicles battery. Incorrect system voltage o
r
voltage fluctuations from a battery charger may
cause programming failure or ECM damage.
- Turn OFF or disable any system that may put a load on the vehicles battery. Turn OFF o
r
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 o
f
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

Battery Charging
Observe the following safety precautions when charging the
battery:
1. Never attempt to charge the battery when the fluid level is
below the lower level line on the side of the battery. In this
case, the battery must be replaced.
2. Pay close attention to the battery during charging procedure.
Battery charging should be discontinued or the rate o
f
charge reduced if the battery feels hot to the touch.
Battery charging should be discontinued or the rate o
f
charge reduced if the battery begins to gas or spew
electrolyte from the vent holes.
3. In order to more easily view the hydrometer blue dot or ring, it may be necessary to jiggle or tilt the battery.
4. Battery temperature can have a great effect on batter
y
charging capacity.
5. The sealed battery used on this vehicle may be either quick charged or slow charged in the same manner as othe
r
batteries.
W hichever method you decide to use, be sure that you completely charge the battery. Never partially charge the
battery.































Jump Starting
Jump Starting with an Auxiliary (Booster)
Battery
CAUTION: Never push or tow the vehicle in an attempt to
start it. Serious damage to the emission system as well as
other vehicle parts will result.
Treat both the discharged battery and the booster battery
with great care when using jumper cables.
Carefully follow the jump starting procedure, being careful
at all times to avoid sparking.
WARNING: FAILURE TO CAREFULLY FOLLOW THE JUMP
STARTING PROCEDURE COULD RESULT IN THE
FOLLOWING:
1. Serous personal injury, particularly to your eyes.
2. Property damage from a battery explosion, battery acid, o
r
an electrical fire.
3. Damage to the electronic components of one or both vehicles particularly.
Never expose the battery to an open flame or electrical spark.
Gas generated by the battery may catch fire or explode.
Remove any rings, watches, or other jewelry before working
around the battery. Protect your eyes by wearing an approved
set of goggles.
Never allow battery fluid to come in contact with your eyes or
skin.
Never allow battery fluid to come in contact with fabrics or
painted surfaces.

3.3 Draining and Filling Cooling System
Draining

Refer to 3.1 Service Notes in this Section, for
important safety items.
1 Allow engine to cool to ambient temperature (less than 50 ° C), and then remove the coolant filler cap (located near
the brake booster assembly).

Disconnection of the battery affects certain
vehicle electronic systems. Refer to 1.1
WARNING, CAUTION and NOTES, before
removing the ground lead.
2 Disconnect the battery ground lead. Refer to 6D1– 3 Battery – V6.
3 Drain the coolant from the system via the radiator drain tap on the lower RHS of the radiator below the lower hose outlet. Attach a suitable piece of rubber tubing to the tap outlet to help direct the flow of the coolant into a suitable
container (capacity at least 12 litres).
Filling
During any service operation that requires the cooling system to be partly or completely drained, the following
instructions must be followed when refilling the cooling system, to ensure that all air is bleed from system.

• Refer to 3.1 Service Notes in this Section,
for important safety items.
• Before opening the radiator bleed screw,
the cooling system must first be
completely depressurised with the engine
coolant filler cap removed.

Do not mix different types of anti-freeze or
corrosion inhibitors, as they may be
incompatible. Always check which coolant is
to be added to the particular vehicle being
serviced. If a different type has been used in
the cooling system (or is added accidentally),
flush the system with clean water. Refer to 3.4
Cleaning Cooling System in this Section.
NOTE
Ensure that the radiator drain tap located at the
bottom of right-hand side radiator tank is closed
before proceeding.
