4.4 • Measure the resistance at the contacts K10 and K5 in the socket
of the cable harness of the seat suspension (STVB C)::
K10 (ground) Ω K5 (voltage 12 V at the
electromagnet for 3/2)
= 28 Ω ±

End of inspection.
>> 28 MΩ(R → ∞)(interruption) or
<< 28 Ω (R → 0) (short-circuit)
Proceed with inspection step no. 4.6.
4.5 • Disconnect the electrical connection (F) between the cable
harness for seat suspension and the cable harness for the
energy bundle.
• Measure the resistance at the contacts K2 and K1 of the socket
of the cable harness for the energy bundle (STVB F):
K2 (ground) Ω K1 (voltage 12 V at the
electromagnet for 2/2)
= 8.6 Ω (±

± 10%)
Replace the cable harness of the seat
suspension (see Chapter 3.16).
>> 8.6 Ω (R → ∞) (interruption) or
<< 8.6 Ω (R → 0) (short-circuit)
Proceed with inspection step no. 4.7.
4.6 • Disconnect the electrical connection (F) between the cable
harness for seat suspension and the cable harness for the
energy bundle.
• Measure the resistance at the contacts K4 and K3 of the socket
of the cable harness for the energy bundle (STVB F):
K4 (ground) Ω K3 (voltage 12 V at the
electromagnet for 3/2)
= 28 Ω ±
