Required Special Tools:
-
MB991348: Test Harness
-
MD998464: Test Harness
Measurement Method
<Measure at the right bank (number 1, 3, 5 cylinders)>
1. Disconnect the injector intermediate connector, and connect the test harness special tool (MD998464) in between.
2. Connect the oscilloscope probe to each injector intermediate connector terminal to analyze each cylinder:
-
Terminal 2 (black clip of special tool) for the number 1 cylinder
-
Terminal 3 (blue clip) for the number 3 cylinder
-
Terminal 4 (white clip) for the number 5 cylinder
<Measure at the right bank (number 2, 4, 6 cylinders)>
1. Disconnect the injector connector, and connect the test harness special tool (MB991348) in between. (All terminals should be connected.)
2. Connect the oscilloscope probe to injector connector terminal 2.
Alternate method (Test harness not available)
1. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 1. (When checking the number 1 cylinder.)
2. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 9. (When checking the number 2 cylinder.)
3. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 24. (When checking the number 3 cylinder.)
4. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 2. (When checking the number 4 cylinder.)
5. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 10. (When checking the number 5 cylinder.)
6. Connect the oscilloscope probe to ECM <M/T> or PCM <A/T> terminal 25. (When checking the number 6 cylinder.)
