DTC B2288: Steering Lock Signal Circuit Malfunction: Description
This DTC is stored when the power source control ECU cannot detect the unlock condition of the steering lock within a specified time.
HINT:
When the power source control ECU is replaced with a new one and the negative (-) battery terminal is connected, the power source mode becomes IG-ON mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2288 | After turning the engine switch from off to on (IG), the steering wheel does not unlock for a certain period of time (ECU unlocks steering wheel only when it receives an unlock signal from LIN communication and cable). |
