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


When the headlamp automatic levelling system initialization * is not implemented, the code No. B2510 is stored. When the headlamp automatic levelling system initialization is completed, the code No. B2510 is cleared automatically.
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


Initialization of the headlamp automatic levelling system is not completed.

PROBABLE CAUSES



DIAGNOSIS PROCEDURE


STEP 1. M.U.T.-III CAN bus diagnostics


Use the M.U.T.-III to diagnose the CAN bus lines.

Q. Is the check result normal?

Go to Step 2.

Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ).

STEP 2. M.U.T.-III diagnosis code


Check if the height sensor related diagnosis code (B2514, B2515 or B2516) or the ETACS-ECU related diagnosis code (B2215 or U0331) is set.

Q. Is the diagnosis code set?

Perform the troubleshooting of the diagnosis code that has been set previously.

Go to Step 3.

STEP 3. Check whether the diagnosis code is reset.


Initialise the headlamp automatic levelling system and check the diagnosis code of the ETACS-ECU.
(1)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(2)Initialise the headlamp automatic levelling system. Refer to .
(3)Check if diagnosis code is set.

Q. Is the diagnosis code set?

Replace the ETACS-ECU.

The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to Cope with Intermittent Malfunction ).
