- When the signal sent via either direct line or CAN communication is malfunctioning and indicates that the vehicle speed is 0 km/h (0 mph), there is no effect on vehicle behavior.
- When the signal sent via either direct line or CAN communication is malfunctioning and indicates that the vehicle is moving, the engine switch cannot be turned from on (IG) to off.

CAUTION / NOTICE / HINT
NOTICE:
- When using the Techstream with the engine switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.
-
The smart key system (for Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart key system (for Start Function) after confirming that the communication systems are functioning properly.
