The measurement values are OK.End of test
NO
The measurement values are not OK.Possible cause and remedy
- B11/4 (Coolant temperature sensor)
End of test
2.3. Check component B11/4 (Coolant temperature sensor) using actual value.
Test prerequisite
- The actual value is not o.k.
Test sequence
- Switch on ignition.
Status of relevant actual value:
- Coolant temperature:Warning! Communication with ECU required.
- Coolant temperature sensor ( Signal voltage ):Warning! Communication with ECU required.
Specified values
- Voltage[20锟斤拷 C]: [3.45...3.32] V
- Voltage[30锟斤拷 C]: [2.93...2.82] V
- Voltage[40锟斤拷 C]: [2.41...2.32] V
- Voltage[50锟斤拷 C]: [1.93...1.86] V
- Voltage[60锟斤拷 C]: [1.51...1.46] V
- Voltage[70锟斤拷 C]: [1.18...1.13] V
- Voltage[80锟斤拷 C]: [0.90...0.87] V
- Voltage[90锟斤拷 C]: [0.70...0.67] V
- Voltage[100锟斤拷 C]: [0.54...0.25] V
- Voltage[110锟斤拷 C]: [0.42...0.40] V
Question
- Are the measurement values OK?
YES
The measurement values are OK.End of test
NO
The measurement values are not OK.Possible cause and remedy
- Line from component B11/4 (Coolant temperature sensor) to component N3/10 (ME-SFI [ME] control unit)
- B11/4 (Coolant temperature sensor)
End of test
3. Check component Y110 (Three-disk thermostat valve).
Test 3.1: Component Y110 (Three-disk thermostat valve) is mechanically damaged or it sticks.
Test 3.2: Test current consumption of component Y110 (Three-disk thermostat valve).
3.1. Component Y110 (Three-disk thermostat valve) is mechanically damaged or it sticks.
Test 3.1.1: Y110 (Three-disk thermostat valve) : Coolant temperature is not reached.
Test 3.1.2: Y110 (Three-disk thermostat valve) : Coolant temperature is too high.
3.1.1. Y110 (Three-disk thermostat valve) : Coolant temperature is not reached.
Warning!Communication with ECU required.
3.1.2. Y110 (Three-disk thermostat valve) : Coolant temperature is too high.
Warning!Communication with ECU required.
3.2. Test current consumption of component Y110 (Three-disk thermostat valve).
