Harness Or Connector INTERMITTENTS

Many intermittent open or shorted circuits come and go with harness/connector movement caused by vibration, engine torque, bumps/rough pavement, etc. Check for this type of condition by performing the applicable procedure from the following list:

• Move related connectors and wiring while monitoring the appropriate scan tool data.
• Move related connectors and wiring with the component commanded ON and OFF, with the scan tool. Observe the component operation.
• With the engine running, move related connectors and wiring while monitoring engine operation.

If harness or connector movement affects the data displayed, component/system operation, or engine operation, check and repair the harness/connections as necessary. See ELECTRICAL CONNECTIONS OR WIRING  .
