*1: If the ambient temperature is approx. -52.9°C (-63.22°F) or lower, DTC B1412/12 may be output even though the system is normal.
*2: The A/C amplifier memorizes the DTC of the respective malfunction if it has occurred for the period of time indicated in the brackets.
*3: For models without an air conditioning system, if this DTC is output, it does not indicate a problem.
*4: for TMC Made and except TMC Made 2ZR-FE
