Technician Safety Information

Safety Precautions
If special testing equipment is required during test drive, note the following:


WARNING!
- In order to avoid risk of accident during road test do the following:
- When reading measuring value blocks, use only the VAS 5051 or the V.A.G 1551 scan tools. Be sure scan tool is fastened securely to rear seat and operated from the rear seat 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.
