Inspection and Verification

NOTE: Upon installation of a new HEC, the module must be reconfigured. For additional information, refer to Module Communications Network (Information Bus).

1. Verify the customer concern by operating the instrument cluster to duplicate the condition. Observe the indicators, warning displays, and gauges to determine if they are operating correctly with the ignition switch:
^ in RUN with the engine off.
^ in START before the ignition switch is released.
^ in RUN with the engine running.







VISUAL INSPECTION CHART
