Procedure

-- Connect both the Test Adapter for ECU (1.0m) VA 6606/7-1 and Test Adapter for ECU (1.7m) VAS6606/7-2 completely to the three isolator boxes VAS6606.

-- Use the following sheets:

Label for Module 1, Cod. A+B VAS6606/1-1 for the Test Adapter - Isolator Box 1 - Breakout Box with Detachable Terminals (198 pins) VAS6606/1
Template VAS6606/2-1 for the Test Adapter - Isolator Box 1 - Breakout Box with Detachable Terminals (198 pins) VAS6606/1-2
Template VAS6606/3-1 for the Test Adapter - Isolator Box 1 - Breakout Box with Detachable Terminals (198 pins) VAS6606/1-3

NOTE:

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

-- Connect the ground wire to a breakout box and to a ground point on the vehicle.

-- Remove the Engine Control Module (ECM), refer to Engine Control Module -J623-, REMOVING AND INSTALLING .

-- Connect the ECM to the Test Adapter for ECU (1.0m) VAS6606/7-1.

-- Connect the wiring harness from the vehicle to the Test Adapter for ECU (1.7m) VAS6606/7-2.

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.

NOTE:

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 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. Use a Vehicle Diagnostic Tester.

NOTE:

When ending "Guided Fault Finding ", the Vehicle Diagnostic 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.
