  1. Disconnect the ECM connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard resistance:
    Tester Connection
    Specified Condition
    A24-27 (TC) - E10-13 (TC)
    Below 1 Ω
    E10-13 (TC) - Body ground
    10 kΩ or higher
  1. Connect the connector.
