SFI System: Precaution

CAUTION: When using the intelligent tester or Techstream, observe the following items for safety reasons:
  • Read its instruction books before using the tester.
  • Prevent the tester cable from being caught on the pedals, shift lever and steering wheel when driving with the tester connected to the vehicle.
  • When driving the vehicle for testing purposes using the tester, 2 persons are required. One person drives the vehicle, and the other operates the tester.
NOTE:
  • After the ignition switch is turned OFF, the navigation system requires approximately 90 seconds to record various types of memory and settings. As a result, after turning the ignition switch OFF, wait 90 seconds or more before disconnecting the cable from the negative (-) battery terminal.
  • Perform RESET MEMORY (AT initialization) for 2WD when replacing the automatic transmission assembly, engine assembly or ECM (see INITIALIZATION ).
  • Perform RESET MEMORY (AT initialization) for 4WD when replacing the automatic transmission assembly, engine assembly or ECM (see INITIALIZATION ).
  • Perform REGISTRATION (VIN registration) when replacing the ECM (see REGISTRATION  ).

HINT:

RESET MEMORY cannot be completed by only removing the battery.
