Code No. B2515 Front height sensor signal
 
 
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 front height sensor, code No. B2515 is set.
 
 
JUDGEMENT CRITERIA
The ETACS-ECU detects the error of the signal voltage from the front height sensor (less than 0.7 V, or 4.2 V or more) or 1 second or longer continuously.
 
 
PROBABLE CAUSES
  • Malfunction of the front height sensor
  • Malfunction of the front height sensor installation
  • Malfunction of the ETACS-ECU
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Check if diagnosis code No. B2514 is set.
Is diagnosis code No. B2514 set?
Perform the troubleshooting of diagnosis code No. B2514.
Go to Step 2.
 
STEP 2. Front height sensor installation status check
Check that the front height sensor is installed properly.
Is the check result normal?
Go to Step 3.
Install the front height sensor properly.
 
STEP 3. Voltage measurement at front height sensor connector (SBF terminal).
(1) Disconnect the connector, and measure at the wiring harness-side connector.
(2) Turn the ignition switch to the ON position.
(3) Measure the resistance between the front height sensor connector (SBF terminal) and body earth.
OK: 5 V
Is the check result normal?
Go to Step 5.
Go to Step 4.
 
STEP 4. Check of open circuit in SBF line between front height sensor connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 5.
Repair the connector(s) or wiring harness.
 
STEP 5. Resistance measurement at front height sensor connector (SGF terminal).
(1) Disconnect the connector, and measure at the wiring harness side.
(2) Measure the resistance between the front height sensor connector (SGF terminal) and body earth.
OK: Continuity exists (2 Ω or less)
Is the check result normal?
Go to Step 7.
Go to Step 6.
 
STEP 6. Check of open circuit in SGF line between front height sensor connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 7.
Repair the connector(s) or wiring harness.
 
STEP 7. Check of short to power supply, short to earth, and open circuit in SHF line between front height sensor connector and ETACS-ECU connector.
Is the check result normal?
Go to Step 8.
Repair the connector(s) or wiring harness.
 
STEP 8. Front height sensor check
Check that the front height sensor is normal (Refer to ).
Is the check result normal?
Go to Step 9.
Replace the front height sensor.
 
STEP 9. M.U.T.-IIISE data list
Check the signal voltage of the front height sensor.
 
Item No.Item nameNormal condition
201Front height sensor signal voltage0.7 V - 4.1 V
OK: Normal condition is displayed.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/inspection Service Points - How to cope with Intermittent Malfunctions ).
Replace the ETACS-ECU.
