Safety Precautions

If special testing equipment is required during road test, note the following:


WARNING!
- Adhere to the following to avoid risk of accident during measurements while driving and road tests:
- Only use VAS5051 or VAG1551 to read out measuring value blocks. The tester must be secured for the rear seat and operated from 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.
