Danger! | Injury hazard when testing or repairing airbags or emergency tensioning retractors | Store airbags with exit surfaces upward, do not expose to temperature above 100 °C. Interrupt power supply when working on airbags. | |
| The battery charge preservation unit must not be connected | ||
| Only remove control module coupling with ignition key removed | ||
| Driver side and passenger side airbags with emergency tensioning retractor, location of components | ||
| Notes on disposal of airbag and emergency tensioning retractor units | ||
| Overview of seats, bunks, restraint systems electrical wiring diagrams | ||
Connection and use of test equipment | |||
Connect Hand-Held Tester, read out fault memory | |||
| All connectors or plug-in connectors (red) of the squibs are designed with short-circuit bridges. When disconnected, the ignition circuit or squib is short-circuited. All work on the airbag and ETR restraint system can therefore be carried out with the ignition key removed. | ||
| Before starting welding work, remove ignition key and disconnect/insulate battery ground cable. Before welding work in the passenger compartment/cargo area, it is absolutely essential to disconnect the coupling from the airbag emergency tensioning retractor control module (A10). | ||
| Cables, connectors and connections are also taken into account when testing with the HHT and in the event of a fault display may have to be checked again separately in accordance with the relevant electric wiring diagram for open-circuit, good contact and correct connection. | ||
| The fault memory can only be read out and erased with the Hand-Held Tester. | ||
