EPS VERIFICATION TEST

For a complete wiring diagram, refer to SYSTEM WIRING DIAGRAMS .

EPS VERIFICATION TEST

  1. Turn the ignition off to the lock position.
  2. Remove all test equipment.
  3. Connect all previously disconnected components and connectors.
  4. Verify all accessories are turned off, the battery is fully charged and the charging system has a status of "recharging".
  5. Verify that the ignition is on. With the scan tool, record and erase all DTCs from all modules. Start the engine and allow it to run for two minutes and fully operate the system that was indicating the failure. NOTE: Turn the steering wheel from lock to lock, holding at each lock position for One second.
  6. Turn the ignition off and wait five seconds. Turn the ignition on and using the scan tool, read Diagnostic Trouble Codes (DTCs) from all modules.
  7. If there are no DTCs present after turning ignition on, road test the vehicle for at least five minutes.
  8. Again, with the scan tool read DTCs. If any DTCs are present, refer to «DTC INDEX»(/dodge/dart/pf-2012-2016/remont/dtc-index/#dtc-index) for the Diagnostic procedure and troubleshoot the new or recurring symptom.
  9. If there are no DTCs present and the customer's concern can no longer be duplicated, the repair is complete. Are any DTCs present or is the original concern still present? Yes Perform the appropriate diagnostic procedure. Refer to «DIAGNOSIS AND TESTING»(ref-646218-S20460472002014072800000) . No Repair is complete.
