Cable and Components, Checking with Breakout Box w/Detachable Terminals (196 Pins) (VAS 6606)

Special tools, testers and auxiliary items required

• Break Out Box, 198-Pin (VAS 6606/1-1)

• Break Out Box, 198-Pin (VAS 6606/1-2)

• Break Out Box, 198-Pin (VAS 6606/1-3)

• Foil (VAS 6606/1-1)

• Foil (VAS 6606/2-1)

• Foil (VAS 6606/3-1)

• Cable Set (VAS 6606/7-1) and (VAS 6606/7-2)

• Always make sure the cables are connected correctly.

• Never use any damaged or worn tools or accessories.

• See operating instructions.

- Connect both cable sets (VAS 6606/7-1) and (VAS 6606/7-2) completely to the 3 breakout boxes (VAS 6606).

- Use the following sheets:

• (VAS 6606/1-1) for the Break out box, 198-pin (VAS 6606/1-1)

• (VAS 6606/2-1) for the Break out box, 198-pin (VAS 6606/1-2)

• (VAS 6606/3-1) for the Break out box, 198-pin (VAS 6606/1-3)

• Make sure all connection bridges are connected completely on all breakout boxes.

- Connect the Ground (GND) wire to a breakout box and to a ground point on the vehicle.

- Remove the engine control module. Refer to => [ Engine Control Module (J623) ] Engine Control Module.

- Connect the Engine Control Module (ECM) to the cable set (VAS 6606/7-1).

- Connect the wiring harness from the vehicle to the cable set (VAS 6606/7-2).

The connection on the ECM consists of a large and small connector.

The large connector has 105 pins and is assigned from "A 1 through A 105" on the breakout box sheet.

The smaller connector has 91 pins and is assigned from "B 1 through B 91" on the breakout box sheet.

The connection will get interrupted when the connection bridge is disconnected.

• The "In contact" - 1 - (red socket) goes to the engine control module.

• The "Out contact" - 2 - (blue socket) goes to the wiring harness.






- Perform test as described in relevant repair sequences.

Installing the ECM

Install in reverse order of removal.

- Check the Diagnostic Trouble Code (DTC) memory and erase if necessary. Use a vehicle diagnostic tester.

• When ending Guided Fault Finding, the tester attempts to erase the DTC memory of all control modules. If this is not successful, the remaining DTCs stored in memory must be corrected until all DTCs can be erased.
