DESCRIPTION
This DTC is stored when the steering lock position signal sent by the steering lock ECU (steering lock actuator or upr bracket assembly) via direct line and the steering lock position signal sent via LIN 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.

---|---|---|---|
B2285 |
The steering lock position signal sent by the steering lock ECU (steering lock actuator or upr bracket assembly) via direct line and the steering lock position signal sent via LIN communication (1-trip detection logic*) do not match. |
|
Disconnect the cable from the negative (-) battery terminal, wait 30 seconds and then reconnect the cable to the negative (-) battery terminal. Wait 40 seconds or more with the engine switch off (with the steering wheel locked), then turn the engine switch on (ACC) (with the steering unlocked) and wait 40 seconds or more. |
