DTC Table
S6RW0C7224006
CAUTION
!
Be sure to perform “Air Conditioning System Check” before starting diagnosis.
NOTE
• History DTC is such DTC which HVAC control module saves in its memory when it detects current
DTC for 60 seconds or more continuously.
• DTC B1504, B1541, B1546, B1570 and B1571 are displayed as a current DTC only when a current
malfunction is detected.
• When HVAC control module detects DTC B1513 and B1514, both current and history DTCs are
displayed at the same time.
