Test sequence
- 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
0278
Component Y49/5 (Right camshaft intake solenoid) has a short circuit to ground. (P2088)
Possible cause:
- Y49/5 (Right camshaft intake solenoid)
Affected functions:
- Engine diagnosis
- Engine output
-------------------------------------------------
Test 1: Check component Y49/5 (Right camshaft intake solenoid).
1. Check component Y49/5 (Right camshaft intake solenoid).
Test 1.1: Test actuation of component Y49/5 (Right camshaft intake solenoid).
Test 1.2: Test current consumption of component Y49/5 (Right camshaft intake solenoid).
1.1. Test actuation of component Y49/5 (Right 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 Y49/5 (Right camshaft intake solenoid).
