5. WARNING LIGHTS AND INDICATORS
1) Engine Tachometer
The tachometer indicates engine speed in revolutions per minute. Multiply 1,000 to the current
number, then it will be the current number of engine revolutions.
Under the normal engine operating temperature, the proper idling speed is 750 ±
for D27DT engine. The red zone (danger rpm range) starts from 4,500 rpm.
1. Connect the tachometer for tune-up test and start the engine.
2. Eliminate the hysteresis by tapping the tachometer.
3. Compare the values on the tester and tachometer and replace the tachometer if the
tolerance is excessive.
- For vehicle equipped with gasoline engine, the indicator shows up to 7,000 rpm and 8,000
rpm. The tolerance at 7,000 rpm is ±100.
If the tachometer pointer vibrates, stands at a certain range or sounds abnormal noise, there
could be defectives in tachometer. If there is a difference between actual engine speed (rpm)
and reading from tachometer, connect a scanner and then compare the value on tachometer
with the reading from scanner.
