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 Y49/7 (Right camshaft exhaust solenoid) to component N3/10 (ME-SFI [ME] control unit)

- Y49/7 (Right camshaft exhaust solenoid)

End of test

0067

Component Y49/7 (Right camshaft exhaust solenoid) has an open circuit in the wiring. (P0013)

Possible cause:

- Y49/7 (Right camshaft exhaust solenoid)

- Voltage supply via component Z7/38 (Circuit 87 M1i connector sleeve)

Affected functions:

- Engine diagnosis

- Engine output

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

Test 1: Power supply

Test 2: Check component Y49/7 (Right camshaft exhaust solenoid).

1. Power supply

Voltage supply via component Z7/38 (Circuit 87 M1i connector sleeve)

Possible cause and remedy

- Check voltage supply according to wiring diagram.

2. Check component Y49/7 (Right camshaft exhaust solenoid).

Test 2.1: Test actuation of component Y49/7 (Right camshaft exhaust solenoid).

Test 2.2: Test current consumption of component Y49/7 (Right camshaft exhaust solenoid).

2.1. Test actuation of component Y49/7 (Right camshaft exhaust 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

2.2. Test current consumption of component Y49/7 (Right camshaft exhaust solenoid).
