Terminal connection diagram

Test steps

1. Open S2 plug connection (cable 2).
   Measure resistance between:
   contact 5 and corresponding contact at engine control unit (DKR),
   contact 41 and corresponding contact at engine control unit (DKV/PWM).
   R _Target = 0 Ω.
2. Check resistance of contacts 5 and 41 (cable 2) to vehicle ground.
   R_Target = ∞ Ω.
