There is an internal fault in component B16/15 (Temperature sensor upstream of SCR catalytic converter).


Possible cause:

- B16/15 (Temperature sensor upstream of SCR catalytic converter)
Affected functions:

- Power generation

-------------------------------------------------

Test 1: Check actual value Exhaust temperature sensor. Plausibility

1. Check actual value Exhaust temperature sensor. Plausibility
Test prerequisite

- Ignition ON
- The engine must be stopped for longer than 6 h.
Status of the relevant actual values:
- B19/11 (Temperature sensor upstream of turbocharger):Warning! Communication with ECU required.

- B19 (TWC temperature sensor):Warning! Communication with ECU required.

- B19/9 (Temperature sensor upstream of diesel particulate filter):Warning! Communication with ECU required.

- B16/15 (Temperature sensor upstream of SCR catalytic converter):Warning! Communication with ECU required.
Specified value

- With the ignition switched on, the values of the temperature sensors may not vary by more than 50° C.
- The actual values must be plausible.
Question

- Are the actual values o.k.?


YES
The actual values are plausible.Further procedure

- In the event of stored faults with a high fault frequency count or in the event of customer complaints, check lines and connectors for loose contact and corrosion..
End of test

NO
The actual values are not plausible.Possible cause and remedy

- Check electrical lines or components whose values are implausible, and repair or replace if necessary.
- Replace component if its value is implausible.
