On-Vehicle Inspection [01/2019 - 09/2022]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECT CIRCUIT OPENING RELAY ASSEMBLY (C/OPN) 
    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      3 - 5 Auxiliary battery voltage is not applied between terminals 1 and 2 10 kΩ or higher
      Auxiliary battery voltage is applied between terminals 1 and 2 Below 1 Ω

      If the result is not as specified, replace the circuit opening relay assembly (C/OPN).
