- Exhaust system
-------------------------------------------------
Test 1: Check power supply of component N3/10 (ME-SFI [ME] control unit).
Test 2: Arrangement of fuses
Test 3: Power supply
Test 4: Check component G3/6 (Right O2 sensor, after TWC [KAT]).
1. Check power supply of component N3/10 (ME-SFI [ME] control unit).
Test 1.1: Test voltage supply of circuit 87. ( Check using actual value )
Test 1.2: Test voltage supply of circuit 30.
Test 1.3: Test voltage supply of circuit 87.
Test 1.4: Test current consumption of component N10/1kR (Circuit 87 relay, engine).
Test 1.5: Test voltage supply of circuit 15.
1.1. Test voltage supply of circuit 87. ( Check using actual value )
Test prerequisite
- The voltage test at component G1 (Battery) is o.k.
- Ignition ON
Status of relevant actual value:
- Battery voltage:Warning! Communication with ECU required.
Specified value
- Battery voltage[11.0 ... 15.0] V
Question:Is the actual value o.k.?
YES
The actual value is okay.End of test
NO
The actual value is not o.k.Possible cause and remedy
- Test voltage supply of circuit 30.
- Test voltage supply of circuit 87.
1.2. Test voltage supply of circuit 30.
Connect socket box to component N3/10 (ME-SFI [ME] control unit).
