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.
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.

---|---|---|---|
B2286 |
The engine speed signal sent by the ECM via direct line and the engine speed signal sent via CAN communication (1- trip detection logic*) do not match. |
|
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. |
P0335 |
The engine speed signal sent by the ECM via direct line and the engine speed signal sent via CAN communication (1- trip detection logic*) do not match. |
|
Allow the engine to idle for 10 seconds or more. |
