Code No. B2510 Height Sensor Not Initialized

caution

If there is any problem in the CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis, always diagnose the CAN bus lines.
Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
When the ETACS-ECU of vehicles without KOS is replaced, the encrypted code of the ignition key needs to be registered to the ETACS-ECU. (If the encrypted code is not registered, the engine cannot be started. Register the encrypted code as described in Immobilizer System - How to Register Key ID .)

DIAGNOSTIC FUNCTION

note

^*: When the height sensor related diagnosis code (B2514, B2515 or B2516) or ETACS-ECU related diagnosis code (B2215 or U0331) is set, initialization of the headlamp automatic levelling system is impossible, therefore perform the troubleshooting for the diagnosis code that has been set previously.

JUDGEMENT CRITERIA
