Operation - Section 3 10/00 OM3023 Page 3-28 Operating Instructions TROUBLESHOOTING Warning Pattern 1 When a problem occurs in the system If the central warning lamp and the ARSC caution lamp flash and the buzzer sounds, it means that a serious problem has occurred in the ARSC system. This system is equipped with a self-diagnostic func- tion. If any problem occurs, a failure code is dis- played by the controller LED below the passenger seat. Operation of the ARSC system is stopped and the retarder is released. Operate the brake pedal or retarder lever as necessary to ensure safety. No.
