- Measure direct current with multimeter between sockets [F.4] 100 and [M.1] 1 of the 126-pole socket box tester.

- Switch on ignition.

Testing of maximum power consumption may be conducted for no longer than 5 s.Specified value

- Amperage[1.0...1.8] 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

- N10/1f43 (Fuse 43)

- Line from component Y49/5 (Right camshaft intake solenoid) to component N3/10 (ME-SFI [ME] control unit)

- Y49/5 (Right camshaft intake solenoid)

End of test

0281

Component Y49/4 (Left camshaft intake solenoid) has a short circuit to positive. (P2093)

Possible cause:

- Y49/4 (Left camshaft intake solenoid)

Affected functions:

- Engine diagnosis

- Engine output

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

Test 1: Check component Y49/4 (Left camshaft intake solenoid).

1. Check component Y49/4 (Left camshaft intake solenoid).

Test 1.1: Test actuation of component Y49/4 (Left camshaft intake solenoid).

Test 1.2: Test current consumption of component Y49/4 (Left camshaft intake solenoid).

1.1. Test actuation of component Y49/4 (Left camshaft intake solenoid).

Test prerequisite

- Engine at idle

- Vehicle stationary

- Coolant temperature > 80锟斤拷 C

- Time since engine start> 60 s

Status of relevant actual value:

- Temperature of coolant:Warning! Communication with ECU required.

Note

- After the actuation it may be necessary to erase the fault memory!

Proceed to 'Actuation' with F2

1.2. Test current consumption of component Y49/4 (Left camshaft intake solenoid).
