DESCRIPTION These DTCs are
stored when the engine speed signal sent by the ECM via direct line and
the engine speed signal sent via CAN communication do not match. |

DTC Detection Condition | Trouble Area |
Note | | B2286 |
Runnable Signal Malfunction |
The
engine speed signal sent by the ECM via direct line and the engine
speed signal sent via CAN communication do not match. (1-trip detection
logic*) |
- SFI system
- Certification ECU (smart key ECU assembly)
- Wire harness or connector
|
- Disconnect the cable from the negative (-) battery terminal, wait 30
seconds and reconnect the cable to the negative (-) battery terminal.
Wait 20 seconds or more with the engine switch off, then start the
engine and maintain an engine speed of 1000 rpm or more for 20 seconds
or more.

Crankshaft Position Sensor Circuit Malfunction (NE Signal) |
The
engine speed signal sent by the ECM via direct line and the engine
speed signal sent via CAN communication do not match. (1-trip detection
logic*) |
- SFI system
- Certification ECU (smart key ECU assembly)
- Wire harness or connector
|
- Allow the engine to idle for 10 seconds or more.
|
- *: Only detected while a malfunction is present and the engine switch is on (IG).
Vehicle Condition and Fail-safe Function when Malfunction Detected |
Vehicle Condition when Malfunction Detected |
Fail-safe Function when Malfunction Detected |
- When a malfunction occurs and the vehicle speed signal sent via either
direct line or CAN communication indicates no vehicle speed, there is no
effect on vehicle behavior. (A malfunction is detected after the engine
switch is turned on (IG).)
- When a malfunction occurs and the vehicle speed signal sent via either
direct line or CAN communication indicates that the vehicle is moving,
the engine cannot be started. However, the engine can be started after
the engine switch has been turned 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, Gasoline Model) 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, Gasoline Model)
after confirming that the communication systems are functioning
properly.

- Inspect the fuses of circuits related to this system before performing the following procedure.
- Before replacing the certification ECU (smart key ECU assembly), refer to Registration.

- After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".
HINT: When the
cable is disconnected and reconnected to the negative (-) battery
terminal, the power source mode returns to the state it was in before
the cable was disconnected. PROCEDURE
