Current Draw, Checking

- Remove seat bench => Body Interior 72 Rear seats; removing and installing seat bench.

- Remove cover - 1 - with Fuel Pump (FP) Control Module (J538) - 2 - from fuel delivery unit.





- Place the test instrument adapter/DSO (5-pin) (VAS 5565) on the connector and on the fuel delivery unit.





- Connect the current clamp - A - to the red wire -with the word "current clamp"- on the test instrument adapter/DSO (5-pin) (VAS 5565).

- Start the engine and run at idle speed.

- Measure current draw of fuel pump. Specified value: max. 9 amps.

• If malfunction in fuel system is sporadic, test can also be performed during a road test, but a second person is required.
