Antitheft and Alarm Systems: Service Precautions

Safety Precautions

If the use of test equipment is required during test drive, note the following


WARNING!
- To reduce the risk of accident when using test equipment, proceed as follows:
- Use only the VAS5051 or VAG1551 to read out measuring value blocks. Tester must always be secured to rear seat and operated from there by a 2nd person.


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, if necessary, erased.
- Always switch ignition off before disconnecting or connecting battery. Failure to do so may damage a control module.
