Component Testing

  1. Measure for 70-110 ohms between terminals 85 and 86 of the powertrain relay.
    • If the resistance is not within the specified range, replace the powertrain relay.
  2. Measure for infinite resistance between the following terminals of the powertrain relay:
    • 30 and 86
    • 30 and 87
    • 30 and 85
    • 85 and 87
      • If continuity is detected, replace the powertrain relay.
  3. Connect a 15A fused jumper wire from the positive terminal of the battery to relay terminal 85. Connect a jumper wire from the negative terminal of the battery to relay terminal 86. Measure for less than 2 ohms between terminals 30 and 87 of the relay.
    • If the resistance measures greater than 2 ohms, replace the powertrain relay.
