Test 1: Check component B40 (Oil sensor (oil level, temperature and quality)).

1. Check component B40 (Oil sensor (oil level, temperature and quality)).

Test 1.1: Check component B40 (Oil sensor (oil level, temperature and quality)) using actual value.

Test 1.2: Check power supply of component B40 (Oil sensor (oil level, temperature and quality)).

1.1. Check component B40 (Oil sensor (oil level, temperature and quality)) using actual value.
Warning!Communication with ECU required.


1.2. Check power supply of component B40 (Oil sensor (oil level, temperature and quality)).
Check power supply of component B40 (Oil sensor (oil level, temperature and quality)).
Test prerequisite

- At least one of the relevant actual values is not okay.
- The power supply of component N3/10 (ME-SFI [ME] control unit) is OK.
Test sequence

- Switch off ignition.
- Connect socket box (126-pin) to component N3/10 (ME-SFI [ME] control unit).
- Connect socket box (35-pin) to component N3/10 (ME-SFI [ME] control unit).
- Measure direct voltage with multimeter between socket (5.5) 5 of the 35-pole socket box tester and socket (3.7) 40 of the 126-pole socket box tester.
- Switch on ignition.
Specified value

- Voltage[4.7...5.3] V
Question
