7.1 • Disconnect the electrical connection (F)
between the belt buckle cable and the cable of
the belt buckle contact.
• Measure the resistance at the pins P1 and P2
in the plug of the belt buckle cable.
P1 Ω P2
= 0.2 Ω (± 10%)
>> 0.2 Ω (→ ∞) (interruption)
<< 0.2 Ω (→ 0) (short-circuit)
End of inspection.
Replace the belt buckle and
the belt buckle cable
(Chapter 3.28).
