54 -CHASSIS ELECTRICAL > 54A-CHASSIS ELECTRICAL > HEADLAMP > DIAGNOSIS CODE PROCEDURES > CODE No. B1E15 HEADLAMP (RH)(LOW BEAM) FET FAIL
Code No.B1E15 Low Beam Lamp(RH) deactivated (FET failure)
 
 
cautionBefore replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
DIAGNOSTIC FUNCTION
Diagnosis code No. B1E15 will be set when the headlamp (Low-beam) (RH) control circuit in the ETACS-ECU fails.
 
 
JUDGEMENT CRITERIA
Diagnosis code No. B1E15 will be set when the ETACS-ECU detects a short to earth in its headlamp (Low-beam) (RH) control circuit.
 
 
PROBABLE CAUSES
  • Headlamp (Low-beam) (RH) control circuit fails
  • Malfunction of the ETACS-ECU
 
 
DIAGNOSIS PROCEDURE
M.U.T.-IIISE diagnosis code
Check if the diagnosis code No. B1E11 is set to the ETACS-ECU.
Is the diagnosis code set?
Carry out the troubleshooting for diagnosis code No. B1E11. On completion, replace the ETACS-ECU when it has not been replaced as the troubleshooting process for diagnosis code No. B1E11. This is because diagnosis code No. B1E15 cannot be erased.
Replace the ETACS-ECU.
