- Measure direct current with multimeter between sockets [F.4] 100 and [M.54] 54 of the 126-pole socket box tester.

- Switch on ignition.

Specified value

- Amperage[0.6...1.2] A

Question

- Is the measurement value OK?

YES

The measurement value is OK.End of test

NO

The measurement value is not OK.Possible cause and remedy

- N10/1f57 (Fuse 57)

- N10/1kR (Circuit 87 relay, engine)

- Check lines from component N3/10 (ME-SFI [ME] control unit) to component Y110 (Three-disk thermostat valve).

- Y110 (Three-disk thermostat valve)

End of test

0160

M16/6 (Throttle valve actuator) : Actual value potentiometer 1 or 2 has failed. (P2135)

Possible cause:

- M16/6 (Throttle valve actuator)

Affected functions:

- Engine diagnosis

- Engine output

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

Test 1: Check component M16/6 (Throttle valve actuator).

1. Check component M16/6 (Throttle valve actuator).

Test 1.1: Check component M16/6 (Throttle valve actuator) using actual value.

Test 1.2: Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).

1.1. Check component M16/6 (Throttle valve actuator) using actual value.

Warning!Communication with ECU required.

1.2. Test voltage supply of the potentiometers of component M16/6 (Throttle valve actuator).

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).

- Measure direct voltage with multimeter between sockets (M.39) 39 and (M.43) 43 of the 35-pole socket box tester.

- Switch on ignition.

Specified value

- Voltage[4.75...5.25] V

Question

- Is the measurement value OK?
