Safety Precautions
If special testing equipment is required during test drive, note the following
WARNING!
- To reduce the risk of accident during road test proceed as follows:
- Only use VAS5051 or VAG1551 to read measuring value blocks. Tester must be secured to the rear seat and operated there by a second technician.
To reduce the risk of personal injury and/or damage of electric and electronic components, always observe the following
- Always switch ignition off before connecting or disconnecting test/measurement tools.
- It is possible that the control module will recognize a malfunction and store a DTC during some tests. After completing all tests and repairs, DTC memory should therefore be checked and erased if necessary.
- Always switch ignition off before disconnecting or connecting battery. Failure to do so may damage a control module.
