Display Group 003

1) Evaluate engine load tolerance range only at idle during "Basic Setting" function 04.

Note on display field 1: Idle speed on vehicles without A/C and rear windshield heater switched on: 750-850 RPM.

Notes on display field 3:
- For the testing at wide open throttle, stop engine, and switch ignition on.
- Since in vehicles with manual transmission and automatic transmission different throttle bodies are installed, the start of opening of the throttle body can be measured with ignition on and thus incorrect installation can be checked.

- Manual transmission: 45-53%
- Automatic transmission: 27-35%





Note on display field 4: If no vehicle speed is shown on VAG 1557 scan tool, first make sure the vehicle speed display is OK. If vehicle speed display is faulty, check vehicle speed sensor wiring diagrams.
