Tech Tips
TOYOTA vehicles are filled with TOYOTA SLLC at the factory. In order to avoid damage to the engine cooling system and other technical problems, only use TOYOTA SLLC or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, non-borate coolant with long-life hybrid organic acid technology (coolant with long-life hybrid organic acid technology consists of a combination of low phosphates and organic acids).
Please contact your TOYOTA dealer for further details.
Note
Never use water as a substitute for engine coolant.
Press the inlet and outlet radiator hoses several times by hand, and then check the level of the coolant.
If the coolant level drops below the F line, add TOYOTA SLLC to the F line.
Install the radiator cap.
Bleed air from the cooling system.
Warm up the engine until the thermostat opens. While the thermostat is open, circulate the coolant for several minutes.
Maintain the engine speed at 2,000 to 2,500 rpm.
Press the inlet and outlet radiator hoses several times by hand to bleed air.
CAUTION:
When pressing the radiator hoses:Wear protective gloves.
Be careful as the radiator hoses are hot.
Keep your hands away from the radiator fan.
Stop the engine and wait until the coolant cools down to ambient temperature.
CAUTION:
Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.
Check the coolant level in the radiator reservoir.
If the coolant level is below the L line, add SLLC to the reservoir F line.
CHECK FUEL FOR LEAKS
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON.
Note
Do not start the engine.
Push the intelligent tester main switch ON.
Select the Active Test and enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.
Check for fuel leaks.
Check that there are no fuel leaks after performing maintenance anywhere on the fuel system.
If there are fuel leaks, repair or replace parts as necessary.
CHECK FOR ENGINE OIL LEAKS
Start the engine, and check that there are no oil leaks after performing maintenance.
CHECK FOR COOLANT LEAKS
Check for engine coolant leaks Click here.
CHECK FUNCTION OF THROTTLE BODY
Check the throttle control motor operating sound.
Turn the ignition switch ON.
When pressing the accelerator pedal, check the operating sound of the running motor. Make sure that no friction noises emit from the motor.
If friction noise is heard, replace the throttle body.
Check the throttle position sensor.
Connect the intelligent tester to the DLC3.
Turn the ignition switch ON.
Under Current Data, check that the throttle valve opening percentage (Throttle Pos) is within the standard.
| Standard throttle valve opening percentage |
|---|
| 60% or more |
Note
When checking the standard throttle valve opening percentage, the shift lever should be in the N position.
If the percentage is less than 60%, replace the throttle body.
CHECK IGNITION TIMING
Warm up the engine and stop the engine.
Note
A warmed up engine should have an engine coolant temperature of over 80°C (176°F), have an engine oil temperature of 60°C (140°F), and the engine rpm should be stabilized.
When using the intelligent tester:
Check the ignition timing.
Connect the intelligent tester to the DLC3.
Start the engine at idle.
Turn the intelligent tester main switch ON.
Enter the following item: Powertrain / Engine and ECT / Data List / IGN Advance.
| Standard ignition timing |
|---|
| 0 to 20° BTDC @ idle |
Tech Tips
Please refer to the intelligent tester operator's manual for further details.
When not using the intelligent tester:
Check the ignition timing.
Using SST, connect tachometer probe to terminal TAC of the DLC3.
Note
Confirm the terminal numbers before connecting them. Connection with a wrong terminal can damage the engine.
Turn off all electrical systems before connecting the terminals.
Clamp the tester probe of a timing light to the 4 lead wires or green-red lead wire of the ignition coil connector for No. 1 cylinder.
Start the engine.
Using SST, connect terminals TC and CG of the DLC3.
Note
When checking the ignition timing, the transmission should be in the neutral position.
Tech Tips
After connecting terminals (TC and CG), engine rpm changes to approximately 1,000 to 1,500 rpm for 5 seconds, then returns to idle speed. Because the ECM checks that the ISC (idle speed control system) operates properly.
Perform the inspection of the ignition timing after engine rpm is returned to idle speed.
Using a timing light, measure the ignition timing.
| Standard ignition timing |
|---|
| 3 to 7° BTDC @ idle |
Remove the SST from terminals 13 (TC) and 4 (CG) of the DLC3.
Check the ignition timing.
| Standard ignition timing |
|---|
| 0 to 20° BTDC @ idle |
Confirm that ignition timing moves to the advanced angle side when the engine speed is increased.
Remove the timing light.
CHECK ENGINE IDLE SPEED
Warm up and stop the engine.
Note
A warmed up engine should have an engine coolant temperature of over 80°C (176°F), have an engine oil temperature of 60°C (140°F), and the engine rpm should be stabilized.
When using the intelligent tester:
Check the idle speed.
Connect the intelligent tester to the DLC3.
Tech Tips
Please refer to the intelligent tester II operator's manual for further details.
Start the engine at idle.
Turn the intelligent tester main switch ON.
Enter the following item: Powertrain / Engine and ECT / Data List / Engine SPD.
| Standard idle speed |
|---|
| 600 to 700 rpm |
Note
When checking the idle speed, the transmission should be in the neutral position.
Switch off all accessories and air conditioning before connecting the intelligent tester.
When not using the intelligent tester:
Check the idle speed.
Using SST, connect tachometer tester probe to terminal 9 (TAC) of the DLC3.
Start the engine at idle.
Check the idle speed.
| Standard idle speed |
|---|
| 600 to 700 rpm |
CHECK CO/HC
Start and warm up the engine.
Run the engine at 2,500 rpm for approximately 180 seconds and idle the engine.
Insert CO/HC meter testing probe at least 40 cm (1.3 ft.) into the tailpipe.
Check CO/HC concentration at idle.
| Idle CO concentration |
|---|
| 0 to 0.5% |
| Idle HC concentration |
|---|
| Applicable local regulation |
If the CO/HC concentration is not as specified, perform troubleshooting in the order given below.
Check the heated oxygen sensor operation Click here.
See the table below for possible causes, and then inspect and repair the applicable causes if necessary.
| CO | HC | Problems | Causes |
|---|---|---|---|
| Normal | High | Rough idle |
|
| Low | High | Rough idle (Fluctuating HC reading) |
|
| High | High | Rough idle (Black smoke from exhaust) |
