| Notes on performing airbag system diagnosis |
| Special tools and workshop equipment required |
| t
| Vehicle system tester -V.A.G 1552- |
| t
| Diagnostic cable -V.A.G 1551/3, 3A, 3B oder 3C- |
| t
| Multimeter, e.g. -V.A.G 1526 A- |
| t
| Test box -VAS 5056- with adapter cable -VAS 5056/1- and -VAS 5056/2- |
WARNING | Check correct fitting and tightness of the wiring and plug connections with the ignition off (also possibly disconnect the plug connections). |
| Before disconnecting the airbag plug connections the mechanic must „electrically discharge himself“. |
| Do not perform any continuity tests or other measurements on the ignition circuits with the airbags and belt tensioners connected! |
| For rectifying faults or determining the cause of the fault, always end self-diagnosis and then re-start it again before separating and re-connecting the individual airbag components! |
| Only the front passenger airbags can be locked → Chapter. Locking of the other airbag unit must only be undertaken in exceptional circumstances and then only by written permission of the PST department (Czech Republic) or the importer. |
| When checking the electrical wiring loom for airbag system for short-circuit or open circuit the airbag plug connections must be disconnected, switch off the ignition and disconnect the battery to check the airbag control unit! |
| When removing and installing the airbag units observe the safety instructions for work on airbag units → Chapter. |
| When removing and installing belt tensioners observe the safety instructions for work on belt tensioners → Chapter. |
|
Note | t
| When disconnecting the battery all values programmed (adaptation values) in vehicle control units are erased. When re-connecting the battery these values must again be programmed! |
