ECM Actuator Circuits (Sidekick)

  1. If an ECM actuator circuit is shorted to ground, ECM could be damaged. Ensure ignition is off. Disconnect ECM connector(s). Check resistance between indicated ECM connector terminals. See the ECM ACTUATOR CIRCUIT RESISTANCE (SIDEKICK)  table.
  2. If resistance is not within specification, check resistance of wiring or components. See appropriate WIRING DIAGRAMS article.
