Strategy-Based Diagnostics

The strategy-based diagnostic is a uniform approach to repair all Electrical/Electronic (E/E) systems. The diagnostic flow can always be used to resolve an E/E system problem and is a starting point when repairs are necessary. The following steps will instruct the technician on how to proceed with a diagnosis:

• Verify the customer complaint. To verify the customer complaint, the technician should know the normal operation of the system.
• Perform preliminary checks as follows:
  • Conduct a thorough visual inspection.
  • Review the service history.
  • Detect unusual sounds or odors.
  • Gather Diagnostic Trouble Code (DTC) information to achieve an effective repair.
• Check bulletins and other service information. This includes videos, newsletters, etc.
• Refer to system check(s).
• Refer to service diagnostics.
