SFI System: Precaution
WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
When using the Techstream, observe the following items for safety reasons:
- Read its instruction books before using the Techstream.
- Prevent the Techstream cable from being caught on the pedals, shift lever and steering wheel when driving with the Techstream connected to the vehicle.
- When driving the vehicle for testing purposes using the Techstream, 2 persons are required. One person drives the vehicle, and the other operates the Techstream.
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.
