Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - 1VD-FTV STARTING
PRE-HEATING SYSTEM - ON-VEHICLE INSPECTION
1. CHECK ILLUMINATION TIME OF GLOW INDICATOR LIGHT |
Check the light illumination duration.
Turn the ignition switch to ON and measure the light illumination time.
- Light illumination time:
- See graph.
*A | w/ DPF | *B | w/o DPF |
*1 | Seconds | *2 | Engine Coolant Temperature °C (°F) |
*3 | Light Illumination Time | - | - |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plug assembly and glow relay.
- HINT:
- Actual light illumination duration may vary slightly from the graph.
Turn the ignition switch off.
2. CHECK PRE-HEATING |
Inspect the pre-heating time.
Turn the ignition switch to ON. Measure how long it takes for the battery voltage to be applied to the glow plugs.
- Standard Pre-Heating Time:
Engine Coolant Temperature Specified Condition 40°C (104°F) or higher 1 second Below 40°C (104°F) See graph*
(Maximum: 21 seconds)
- HINT:
- *: The pre-heating time changes depending on the battery voltage.
*1 | Seconds | *2 | Battery Voltage (V) |
*3 | After Glow Time | - | - |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plug assembly and glow relay.
Turn the ignition switch off.
3. CHECK AFTER GLOW TIME |

Remove the No. 1 glow relay (GLOW 1) from the engine room relay block.
Remove the No. 2 glow relay (GLOW 2) from the engine room relay block.
After the engine starts, measure the time duration that battery voltage remains present.
- Standard After Glow Time:
Tester Connection Condition Specified Condition 2 - Body ground After engine starts Refer to graph below 2 - Body ground
*A | w/ DPF | *B | w/o DPF |
*1 | Seconds | *2 | Engine Coolant Temperature °C (°F) |
*3 | After Glow Time | - | - |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plug assembly and glow relay.
