Connect Test Box For Wiring Test

Recommended special tools and equipment e.g.:







- VAG1598/31 test box

Requirement

- Ignition switched off.

Procedure
- Remove wiper arms and wind cowl.
- Then disengage connector from control module and disconnect.







- Connect VAG1598/31 test box at control module wiring harness. Engine Control Module (ECM) is not connected.

When harness connectors are disconnected from the Engine Control Module (ECM) or the battery is disconnected, all adaptation values in the control module are erased. DTC memory content will remain intact however. If the engine is started after this, a rough, uneven idle can result. In this case, the readiness code must be generated again.
