2.8 • Measure the resistance at the contacts K10 and K7 in the socket
of the cable harness of the seat suspension (STVB C):
K10 (ground) Ω K7 (voltage 12 V at the
electromagnet for 2/2)
= 28.5 Ω (±
±±
± 1%)
End of inspection.
>> 28.5 Ω (R → ∞) (interruption) or
<< 28.5Ω (R → 0) (short-circuit)
Proceed with inspection step no. 2.10.
2.9 • Disconnect the electrical connection (B) between the sensor
module and the cable harness for seat suspension.
• Measure the resistance at the pins P3 and P1 at the plug of the
sensor module (STVB B):
P3 (ground) Ω P1 (voltage 12 V at the
electromagnet for 3/2)
= 28.5 Ω (±
±±
± 1%)
Replace the cable harness of the seat
suspension (see Chapter 3.16).
>> 28.5 Ω (R → ∞) (interruption) or
<< 28.5 Ω (R → 0) (short-circuit)
Replace the sensor module
(see Chapter 3.9).
