AFGS (ACTIVE PEDESTRIAN PROTECTION) PROCEDURE AFTER ACCIDENT

The AFGS system consists of the following components:

• Satellites (control unit + sensor)
  • Sensors, inside, bumper trim, left/middle/right
  • ACSM control unit (Crash Safety Module)
• Cables and connectors
• Engine compartment lid hinges
  • Actuator
  • Engine compartment lid hinge
• Engine compartment lid catch
  • Catch, engine compartment lid
  • Catch, upper section (striker)

In case of a frontal or side collision in the area of the engine compartment lid and/or the A-pillars, check the following components:

Satellites (control unit + sensor)

• Procedure
  • Read fault memory
  • Disconnect battery and observe waiting period
  • Rectify faults
  • Reconnect battery and observe waiting period
  • Delete fault memory
  • Turn off ignition and wait at least 2 minutes (no consumers may be switched on during this period such as e.g. interior lights, radio, etc.)
  • Switch on ignition.
  • Clear fault memory and if necessary rectify faults

Cables and connectors

• Procedure
  • Check cables and connectors for damage, replace if necessary.

Procedure if AFGS was activated

Engine compartment lid hinges

• Replace both engine compartment lid catches
• Check the top sections of the catch and replace if necessary

Procedure if AFGS was not activated

Engine compartment lid hinges

• Check BOTH HINGES OF THE ENGINE COMPARTMENT LID and replace if necessary
• Only if the hinges are faulty, replace the ACTUATOR

Engine compartment lid catch

• Check BOTH ENGINE COMPARTMENT LID CATCHES and replace if necessary.
• Check the top section of the catch and replace if necessary.

Blind Rivets

1.0 Recommended tools and equipment

• Blind riveting tongs
• Rivet head extension

Setting blind rivets

• Refer to repair instruction for rivet size.
• Position bore holes for blind rivets as specified in repair instruction. If necessary, carry over the positions of the rivets to the new component.
• Drill holes (0.2 mm bigger than the outside diameter of the rivet. Example 4.2 mm dia. for 4 mm rivet and 6.7 mm dia. for 6.5 mm rivet).
• Deburr holes.
• APPLY ADHESIVE.
• Insert blind rivet. If necessary, remove adhesive that has emerged.

  Position blind rivet tool vertically. Use rivet head extension if accessibility is poor.

• Rivet blind rivet with blind rivet tool. In the meantime clean rivet head if fouled with adhesive.

  Risk of damage to rivet head by penetrating adhesive.

• Seal blind rivets with SEALANT D1 (risk of corrosion).
• Seal cavities after painting vehicle with CAVITY SEALANT (risk of corrosion).
