Wiring and Component Testing With Breakout Box W/Detachable Terminals (196 Pins) (VAS 6606) From MY 11

Wiring and Component Testing with Breakout Box w/Detachable Terminals (196 pins) (VAS 6606) from MY 11

Special tools, testers and auxiliary items required

• Breakout Box (VAS 6606/1)

• Breakout Box (VAS 6606/2)

• Breakout Box (VAS 6606/3)

• Sheet for Breakout Box (VAS 6606/1-1)

• Sheet for Breakout Box (VAS 6606/2-1)

• Sheet for Breakout Box (VAS 6606/3-1)

• Cable Set (VAS 6606/7)

• Always make sure the cables are connected correctly.

• Never use any damaged or worn tools or accessories.

• Always read the operating instructions that come with the (VAS 6606).

- Connect the (VAS 6606/7) to the (VAS 6606).

- Use the following sheets:

• (VAS 6606/1-1) for VAS 6606/1

• (VAS 6606/2-1) for VAS 6606/2

• (VAS 6606/3-1) for VAS 6606/3

• 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) ] Service and Repair.

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

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

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 ECM.

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






- Perform test as described in relevant repair sequences.

Installing ECM

Install in reverse order of removal.

The procedures to follow after connecting the new ECM are described in Guided Fault Finding and Guided Functions.

• When ending Guided Fault Finding, the tester attempts to erase the Diagnostic Trouble Code (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.
