Engine - On-Vehicle Inspection

Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1VD-FTV ENGINE MECHANICAL

ENGINE - ON-VEHICLE INSPECTION

1. INSPECT ENGINE IDLE SPEED
  • NOTICE:
Turn all the electrical systems and the A/C off.
When checking the idle speed, move the shift lever to neutral.
  • HINT:
For more information about the GTS, refer to its operator's manual.
If an GTS is not available, use a tachometer tester probe as a substitute.

When using the GTS:

Warm up the engine.

Connect the GTS to the DLC3.

Enter the following menus:


Powertrain / Engine / Data List / Engine Speed.

  • HINT:
  • Refer to the GTS operator's manual for help selecting the Data List.

Inspect the engine idle speed.

  • Standard Idle Speed:
  • ItemSpecified Condition
    for Automatic Transmission550 to 750 rpm
    for Manual Transmission500 to 600 rpm

Disconnect the GTS from the DLC3.

When not using the GTS:

Warm up and stop the engine.

Connect a tester probe of a tachometer to terminal 9 (TAC) of the DLC3 with SST.

  • SST
  • 09843-18040

Inspect the engine idle speed.

  • Standard Idle Speed:
  • ItemSpecified Condition
    for Automatic Transmission550 to 750 rpm
    for Manual Transmission500 to 600 rpm

Disconnect the tester probe from terminal 9 (TAC) of the DLC3.

2. INSPECT MAXIMUM ENGINE SPEED

Start the engine.

Fully depress the accelerator pedal.

Check the maximum engine speed.

  • Maximum engine speed:
  • 4700 to 4900 rpm
3. INSPECT COMPRESSION

Warm up and stop the engine.

Disconnect the cable from the negative (-) battery terminal.

Remove the No. 1 glow plug connector.

w/ Intercooler:


Remove the intercooler assembly ().

Remove the injection pipes ().

Remove the No. 1 glow plug connector.

Reinstall the injection pipes ().

Remove the 8 glow plugs ().

Disconnect all connectors from the 8 injectors.

Connect the cable to the negative (-) battery terminal.

Inspect the cylinder compression pressure.

Insert SST (attachment) into the glow plug hole.

  • SST
  • 09992-00026(09992-00410,09992-00211)
  • Torque:
  • 13 N*m{ 133 kgf*cm, 10 ft.*lbf}
Text in Illustration
*1SST (Compression Gauge)
*2SST (Attachment)

Connect SST (compression gauge) to SST (attachment).

While cranking the engine, measure the compression pressure.

  • Standard compression pressure (normal condition):
  • 2700 kPa (27.5 kgf/cm2, 392 psi)
  • Minimum compression pressure:
  • 2200 kPa (22.4 kgf/cm2, 319 psi)
  • Difference between each cylinder:
  • 500 kPa (5.1 kgf/cm2, 73 psi) or less
  • NOTICE:
Use a fully-charged battery so the engine speed can be increased to 280 rpm or more.
Inspect the other cylinders in the same way.
Measure the compression as quickly as possible.

If the cylinder compression is low, pour a small amount of engine oil into the cylinder through the glow plug holes. Then inspect the cylinder compression again.


If adding oil increases the compression pressure, the piston rings and/or cylinder bore may be worn or damaged.


If the pressure stays low, the valve may be stuck or seated improperly, or there may be leakage from the gasket.

Remove SST (attachment and compression gauge).

Disconnect the cable from the negative (-) battery terminal.

Connect all connectors to the 8 injectors.

Install the 8 glow plugs ().

Install the No. 1 glow plug connector.

Remove the injection pipes ().

Reinstall the No. 1 glow plug connector.

Install the injection pipes ().

w/ Intercooler:


Install the intercooler assembly ().
