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

- 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.
