Relay Test

  1. Vehicle OFF, disconnect the KR119 charge port door relay.
  2. Test for 60-200 Ω between terminals 85 and 86.
    • If less than 60 Ω or greater than 200 Ω 

      Replace the KR119 charge port door relay.

    • If between 60-200 Ω 
  3. Test for infinite resistance between the terminals listed below:
    • 30 and 86
    • 30 and 87
    • 30 and 85
    • 85 and 87
    • If less than infinite resistance 

      Replace the KR119 charge port door relay.

    • If infinite resistance 
  4. Install a 3 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground.
  5. Test for less than 2 Ω between terminals 30 and 87.
    • If 2 Ω or greater 

      Replace the KR119 charge port door relay.

    • If less than 2 Ω 
  6. All OK
