Circuit/System Testing

  1. Ignition ON, engine OFF.
  2. Disconnect the KS harness connector.
  3. Measure for 2-5 volts between each of the following circuits and ground on the ECM side of the harness connector:
    • The KS signal circuit, terminal 1
    • The KS signal circuit, terminal 2
    • If less than the specified range, test the circuits for a short to ground or an open/high resistance. If the circuits test normal, replace the ECM.
    • If greater than the specified range, test the circuits for a short to voltage. If the circuits test normal, replace the ECM.
  4. If the circuits test normal, replace the KS.
