Code No. B2513 Levelling actuator output voltage


caution
  • 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



JUDGEMENT CRITERIA



PROBABLE CAUSES



  • Malfunction of headlamp assembly (headlamp levelling unit)
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors

DIAGNOSIS PROCEDURE


STEP 1. Check of short to power supply, short to earth circuit in MSL line between headlamp assembly (LH) connector and ETACS-ECU connector.


Q. Is the check result normal?





STEP 2. Check whether the diagnosis code is reset.


Q. Is diagnosis code No. B2513 set?





STEP 3. Check of short to power supply, short to earth circuit in MSR line between headlamp assembly (RH) connector and ETACS-ECU connector.


Q. Is the check result normal?





STEP 4. Check whether the diagnosis code is reset.


Q. Is diagnosis code No. B2513 set?





STEP 5. M.U.T.-III data list


(1)Disconnect the headlamp assembly (LH) and headlamp assembly (RH) connector.
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
Item No.
 Item name
 Normal condition
Item 418
 A/L actuator output voltage
 Indicates the voltage value of system voltage within the range of 20 to 80%.
OK: Normal condition is displayed.

Q. Is the check result normal?





STEP 6. Check the headlamp assembly (LH).



(1)Disconnect the headlamp assembly (RH) connector.
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3)Perform the drive test using the M.U.T.-III. Refer to .

Q. Is the check result normal?





STEP 7. Check the headlamp assembly (RH).



(1)Disconnect the headlamp assembly (LH) connector.
(2)Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3)Perform the drive test using the M.U.T.-III. Refer to .

Q. Is the check result normal?





STEP 8. Check whether the diagnosis code is reset.


Q. Is diagnosis code No. B2514 set?
