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.
 
 
 
 
DIAGNOSTIC FUNCTION
If a trouble occurs in headlamp assembly (headlamp levelling unit), code No. B2513 is set.
 
 
JUDGEMENT CRITERIA
The ETACS-ECU detects the short-circuit of the signal line to the headlamp assembly (headlamp levelling unit) for 1 second or longer continuously.
 
 
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.
Is the check result normal?
Go to Step 2
Repair the connector(s) or wiring harness.
 
STEP 2. Check whether the diagnosis code is set again.
Is diagnosis code No. B2513 set?
Go to Step 3
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to cope with Intermittent Malfunction ).
 
STEP 3. Check of short to power supply, short to earth circuit in MSR line between headlamp assembly (RH) connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 4
Repair the connector(s) or wiring harness.
 
STEP 4. Check whether the diagnosis code is set again.
Is diagnosis code No. B2513 set?
Go to Step 5
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to cope with Intermittent Malfunction ).
 
STEP 5. M.U.T.-IIISE 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 nameNormal condition
206Levelling actuator output voltageIndicates the voltage value of system voltage within the range of 20 to 80%.
OK: Normal condition is displayed.
Is the check result normal?
Go to Step 6
Go to Step 8
 
STEP 6. Check the headlamp assembly (LH).
Check the headlamp assembly (LH) for internal failure.
(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.-IIISE. Refer to .
Is the check result normal?
Go to Step 7
Replace the headlamp assembly (LH).
 
STEP 7. Check the headlamp assembly (RH).
Check the headlamp assembly (RH) for internal failure.
(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.-IIISE. Refer to .
Is the check result normal?
Go to Step 8
Replace the headlamp assembly (RH).
 
STEP 8. Check whether the diagnosis code is set again.
Is diagnosis code No. B2514 set?
Replace the ETACS-ECU.
The diagnosis is complete.
