-------------------------------------------------
Test 1: Check power supply of component N3/10 (ME-SFI [ME] control unit).
Test 2: Arrangement of fuses
Test 3: Check component Y10/1 (Power steering pump pressure regulator valve).
1. Check power supply of component N3/10 (ME-SFI [ME] control unit).
Test 1.1: Test voltage supply of circuit 15.
Test 1.2: Test voltage supply of circuit 87. ( Check using actual value )
Test 1.3: Test voltage supply of circuit 30.
Test 1.4: Test voltage supply of circuit 87.
Test 1.5: Test current consumption of component N10/1kR (Circuit 87 relay, engine).
1.1. Test voltage supply of circuit 15.
Connect socket box to component N3/10 (ME-SFI [ME] control unit).
