YES



The measurement values are OK.End of test



NO



The measurement values are not OK.Possible cause and remedy



- B2/5b1 (Intake air temperature sensor)



End of test



2. Check component B14 (Ambient temperature display temperature sensor).



Test 2.1: Check component B14 (Ambient temperature display temperature sensor).



2.1. Check component B14 (Ambient temperature display temperature sensor).



Test prerequisites



- The power supply of component N10/1 (Driver-side SAM control unit with fuse and relay module) is OK.



- Fault code 9063 is current, and (or) at least one of the relevant actual values is not OK.



Test sequence



- Detach coupling at component B14 (Ambient temperature display temperature sensor).



- Connect resistance simulator to the connector of component B14 (Ambient temperature display temperature sensor).



- Connect resistance substitution unit between sockets (B14)1 and (B14) 2



- Adjust resistance values one after another and compare them with the actual value.



Status of relevant actual value:



- B14 (Ambient temperature display temperature sensor):Warning! Communication with ECU required.



Specified value



- Resistor9.6 kohms:Temperature: [0锟斤拷 C]



- Resistor5.9 kohms:Temperature: [10锟斤拷 C]



- Resistor3.7 kohms:Temperature: [20锟斤拷 C]



- Resistor2.4 kohms:Temperature: [30锟斤拷 C]



- Resistor1.6 kohms:Temperature: [40锟斤拷 C]



Question:Is the actual value o.k.?
