	Notes on safety-relevant components		AH00.00-Z-0019-01A
		For the repair, use only the "MCP" contact family approved for this connection.
		If twisted lines are twisted for repair, then twist them again up to the contact.
		Only perform repair on contacts with single-wire sealing (ELA).
		Repair max. 10 contacts.
		This repair is prohibited for a seal concept with mat seal.

		Perform this test very carefully. Otherwise, if signals are mixed up, there is a risk of death for the vehicle occupants.
		Then perform a function test on the basis of the wheel speed for each repair.
		To do so, turn each wheel and ensure that it matches the wheel turned.
