Terminal connection diagram

Test steps

1. Open plug connections S2 and S3.
   Measure resistance between:
   contact 17 and contact A (CAN-H),
   contact 37 and contact B (CAN-L)
   contact 36 and contact C (CAN-M)
   .
   R_Target = 0 Ω.
2. S2: Check resistance of contacts 17, 36 and 37 (cable 2) to vehicle ground.
   R_Target = ∞ Ω.
