  1. Test for one of the following resistance specifications between terminals 85 and 86 of the KR75 powertrain relay:
    • 70-110 Ω
    • 200-250 Ω
    • If not within the specified range, replace the KR75 powertrain relay.
  2. Test for infinite resistance between the following terminals of the KR75 powertrain relay:
    • 30 and 86
    • 30 and 87
    • 30 and 85
    • 85 and 87
    • If not the specified value, replace the KR75 powertrain relay.
  3. Install a 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 Ω between terminals 30 and 87.
    • If greater than the specified range, replace the KR75 powertrain relay.
