The following table illustrates the ECM connector locations:

- Use the J 35616 Connector Test Adapter Kit for any test that requires probing the ECM harness connector or a component harness connector.
- Performing the fuel injector coil test may help isolate an intermittent condition. Refer to Fuel Injector Coil Test .
- If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the circuit status for the component with a scan tool. The circuit status parameter changes from OK or Indeterminate to Fault if there is a condition with the circuit or a connection. The ODM information is in the output driver module (ODM) data list.
- If the condition is intermittent, refer to Intermittent Conditions .
