Airbagsensor ausbauen

kressi · 19. Mai 2015

Hallo,

jetzt kommt die letzte Baustelle an meinem neuen alten RAM

Die Airbagleuchte leuchtet und der Vorbesitzer hat den Fehler bereits auslesen lassen. Ist der Airbagsensor der wohl irgendwo unter der vorderen Stoßstange verbaut sein muss. Den Sensor hat er mir auch mitgegeben. Gestern beim Ölwechsel habe ich schon nach dem Sensor gesucht, aber nichts gefunden.

Hat einer von Euch einen Tipp wo der unter der Stoßstange steckt? Kommt man da hin ohne die komplette Stoßstange auszubauen und muss danach der Fehlerspeicher gelöscht werden?

Sonnige Grüße aus Lauf!
Steffen

Keine Ahnung welches BJ. Du fährst, und somit auch nicht wo Dein G-sensor verbaut ist. Fehlerspeicher brauch aber nicht gelöscht werden, da das Airbagmodul jedes mal beim Start nen Selbsttest durchführt... und wenn kein Fehler dann funktioniert es auch.

Sorry, Baujahr ist 2010.

Die erste große Fahrt hat mein RAM mit Wohnwagen nach Kroatien hinter sich. Fährt wie eine eins wenn jetzt noch das Airbag-Lichtel weg wäre...

Hat jemand noch einen Tipp wo der Sensor beim RAM 2010 in der Stoßstange steckt?

Viele Grüße
Steffen

Vorneweg die Warmhinweise:

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

WARNING: To avoid serious or fatal injury, never strike or drop the front impact sensor, as it can damage the impact sensor or affect its calibration. The front impact sensor enables the system to deploy the front Supplemental Restraint System (SRS) components. If an impact sensor is accidentally dropped during service, the sensor must be scrapped and replaced with a new unit. Failure to observe this warning could result in accidental, incomplete, or improper front SRS component deployment.

Ausbau:

1. Disconnect and isolate the battery negative cable. Wait two minutes for the system capacitor to discharge before further service.
2. Disconnect the Front End Module (FEM) (1) wire harness connector (4) from the right or left front impact sensor (5) connector receptacle.
3. Remove the screw (2) that secures the front impact sensor to the back of the right or left end of the lower radiator crossmember (3).
4. Remove the right or left front impact sensor from the engine compartment.

Beim Einbau den letzten Satz beachten:

1. Position the right or left front impact sensor (5) onto the back of the right or left end of the lower radiator crossmember (3). Be certain that the anti-rotation pin on the back of the sensor is engaged in the clearance hole of the crossmember.
2. Install and tighten the screw (2) that secures the sensor to the back of the crossmember. Tighten the screw to 10 N·m (90 in. lbs.).
3. Reconnect the Front End Module (FEM) (1) wire harness connector (4) to the sensor connector receptacle.
4. Do not reconnect the battery negative cable at this time. The Supplemental Restraint System (SRS) verification test procedure should be performed following service of any SRS component. (Refer to 10 - Restraints - Standard Procedure) .

Und hier noch die Standard Procedure:

SUPPLEMENTAL RESTRAINTS VERIFICATION TEST

NOTE: The following procedure should be performed using a diagnostic scan tool to verify proper Supplemental Restraint System (SRS) operation following the service or replacement of any SRS component. Refer to the appropriate diagnostic procedures.

WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.

1. During the following test, the battery negative cable remains disconnected and isolated, as it was during the Supplemental Restraint System (SRS) component removal and installation procedures.
2. Be certain that the diagnostic scan tool contains the latest version of the proper diagnostic software. Connect the scan tool to the 16-way Data Link Connector (DLC) (2). The DLC is located on the driver side lower edge of the instrument panel, near the steering column opening cover (1) and outboard of the steering column.
3. Turn the ignition switch to the ON position and exit the vehicle with the scan tool.
4. Check to be certain that nobody is in the vehicle, then reconnect the battery negative cable.
5. Using the scan tool, read and record the active (current) Diagnostic Trouble Code (DTC) data.
6. Next, use the scan tool to read and record any stored (historical) DTC data.
7. If any DTC is found in Step #5 or Step #6 , refer to the appropriate diagnostic information.
8. Use the scan tool to erase the stored DTC data. If any problems remain, the stored DTC data will not erase. Refer to the appropriate diagnostic information to diagnose any stored DTC that will not erase. If the stored DTC information is successfully erased, go to Step #9 .
9. Turn the ignition switch to the OFF position for about 15 seconds, and then back to the ON position. Observe the airbag indicator in the instrument cluster. It should light from four to six seconds, and then go out. This indicates that the SRS is functioning normally and that the repairs are complete. If the airbag indicator fails to light, or lights and stays ON, there is still an active SRS fault or malfunction. Refer to the appropriate diagnostic information to diagnose the problem.
