Connect pressure line -1- of
tester to adapter -VAS 6394/3-. |
|
|
|
| – |
Connect vehicle and fuel pressure sender - G247-
electrically using test instrument adapter/DSO (3-pin) -VAS

| – |
Compare pressure displayed on tester -VAS 6394/1- with
actual value displayed on vehicle diagnostic tester. |
| – |
Watch the fuel pressure on the vehicle diagnostic tester. |
| A maximum pressure deviation of 5 bar is permissible. |
| – |
If the deviation is greater than 5 bar, renew fuel pressure
sender - G247-. |
| – |
Repeat test with new fuel pressure sender - G247- and
compare both measured values. |
| – |
If measured values are now the same, install new fuel
pressure sender - G247-. |
| – |
If measured values are not the same again, check electrical
