DTC Set Conditions

• This DTC is set under one of the following cases while the SRS-ECU is monitoring the passenger seat belt warning light drive circuit:
  • When a short circuit occurs in the passenger seat belt warning light drive circuit.
  • When a malfunction is detected in the output transistor inside the SRS-ECU.

However, if the vehicle condition returns to normal, DTC B1486 will be automatically erased, and the passenger seat belt warning light will go out.
