COOLING SYSTEM
Coolant Level
Check the coolant level and replenish the radiator reserve
tank as necessary.
If the coolant level falls below the “MIN” line, carefully
check the cooling system for leakage. Then add enough
coolant to bring the level up to the “MAX” line.



Engine coolant Filling up procedure
1. Make sure that the engine is cool.
Warning:
When the coolant is heated to a high temperature, be
sure not to loosen or remove the rediator cap.
Otherwise you might get scalded by hot vapor or
boiling water.
To open the radiator cap, put a piece of thick cloth on
the cap and loosen the cap slowly to reduce the
pressure when the coolant has become cooler.
2. Open rediator cap pour coolant up to filler neck
3. Pour coolant into reservoir tank up to “MAX” line
4. Tighten radiator cap and start the engine. After idling for 2 to 3 minutes, stop the engine and reopen radiator
cap. If the water level is lower, replenish.
5. After replenish the coolant tighten radiator cap, warm up the engine at about 2000 rpm. Set heater
adjustment to the highest temperature position, and let
the coolant circulate also into heater water system.
6. Check to see the thermometer, continuously idling 5 minutes and stop the engine.
7. W hen the engine has been cooled, check filler neck for water level and replenish if required. Should
extreme shortage of coolant is found, check the
coolant system and reservoir tank hose for leakage.
8. Pour coolant into the reservoir tank up to “MAX” line.

ENGINE CONTROL SYSTEM (4JK1/4JJ1) 6E-349
4. 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 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 Selection screen and click “Next”.
f. Click “Close” on the Security Access Enabled screen.
g. Turn OFF the scan tool.
h. Disconnect the scan tool from the terminal.
5. Install a scan tool to the vehicle.
6. Turn ON the ignition, with the engine OFF.
7. Select Diagnostics > appropriate vehicle identification > 4JK1 or 4JJ1 > Programming >
Program ECU.
8. Verify the VIN on the screen if programmed at previously described SPS. If not programmed or
incorrect VIN, input correct VIN.
9. Input 24 digits of each fuel injector 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 the Diagnostic System
Check - Engine Controls if needed.
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 Learn > Learning > Learned.
3. If the ECM has correctly learned the fuel supply pump current adjustment, the Supply Pump Status
parameter on the scan tool will repeatedly indicate
Learning and 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.
Service Programming Methods
The two methods of programming an ECM are listed
below:
• Remote Programming
• Pass Thru Programming
For information on programming an ECM 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 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:
• When a service procedure instructs you to replace the ECM.
• 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.
