CAUTION / NOTICE / HINT
Note
Turn the ignition switch off for 60 seconds before performing the following inspections.
PROCEDURE
INSPECT ILLUMINATION DURATION OF GLOW INDICATOR LIGHT
| *a | Glow Indicator Lighting Time |
| *b | Engine Coolant Temperature |
Turn the ignition switch to ON and measure the length of time that the light remains illuminated.
| Lighting time |
|---|
| Refer to the graph |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.
INSPECT PRE-HEATING
| *a | Pre-heating Time |
| *b | Battery Voltage |
Turn the ignition switch to ON and measure the length of time that battery voltage is applied to the glow plugs.
| Engine Coolant Temperature | Specified Condition |
|---|---|
| 40°C (104°F) or higher | 1 second |
| Below 40°C (104°F) | Refer to the graph (15 seconds at longest) |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.
Turn the ignition switch to START, and check that battery voltage is applied to the glow plugs.
While cranking the engine, measure the time that battery voltage is applied to the glow plugs.
| Engine Coolant Temperature | Specified Condition |
|---|---|
| 40°C (104°F) or higher | 1 second |
| Below 40°C (104°F) | Refer to the graph (15 seconds at longest) |
INSPECT AFTER GLOW TIME
| *a | After Glow Time |
| *b | Engine Coolant Temperature |
After starting the engine, measure the time that battery voltage is applied to the terminal SREL of the ECM.
| After glow time |
|---|
| Refer to the graph |
If the result is not as specified, check the ECM, engine coolant temperature sensor, glow plugs and glow plug relay.
